Sample letter sending billing statement for Quality Assurance

kyway kyway means quality assurance and the first question I will ask is what is quality assurance what is quality assurance quality assurance quality assurance is trying to make sure that a product meets the user's need quality assurance is trying to make sure that a product is useful to the user a a H an ATM that is a machine where you get money from that does not function cannot meet the need of the user a cup that I mean you need to use to drink that has a hole under it it is not useful to the user because if you put water in it the water will flow out a cloth that is tor I mean if you go to Walmart for example you buy buy a cloth and you see the cloth is T definitely you just drop it you don't want to buy it you don't want to pay money for it why because it does not meet your need your need is to put on a nice cloth if you go to the meat section you want to buy meat and you see a meat that is rotten you will drop it because you don't want that so what does quality assurance have to do with this and who does quality assurance I remember there was a time I always tell this story that I uh when I was living in Europe I used to do some part-time business I go to China I bring in some containers into Europe uh of some you know Electronics goods and all those kind of stuff when I get to China in the factory where they produce this uh these Goods the the the factory workers once they produce for example let's take an example of microwave they producing microwave once they produce every 50 microwave they take the fifth microwave to the side they push it to the side they don't pack it they don't pack it why are they pushing it to the side they are pushing it to the side for those quality assurance people to test it to make sure that that microwave is functioning they are not testing every microwave because they produce hundreds of thousands of microwave every day and it is not possible for them to test every microwave so they test every fifth microwave how do they test it they plug it to the wall they try to put some food in it they warm it they they turn on the timer they I mean they do several kinds of things on the microwave to make sure that it is functioning once it is functioning they put it in package and they shift it forward so why are they trying to do this why I mean I I I mean you can look at them I mean I understood the reason why they trying to do this but not everybody will understand the reason for example if this company produces without controlling what they're doing and every day they produce a 100,000 pieces of microwave and they ship it out to customers and customers test these products and the products are not good what will happen customers will return the products to the factory and the factory will have to pay for returning the products back to them isn't it so now tell me who has lost the factory the manufacturers have lost the money they are supposed to collect from the customers they have lost the money they spent on the on the workers they have lost the money they spend on shipment in and out because they have to pay for the shipment if the products are not good so that is why companies do quality assurance companies do quality assurance so that the product that they send out will meet the end users's need what is the need of a microwave a microwave is to war food so if you buy microwave from Walmart for example you put food in it and you warm it and it doesn't warm then definitely you just put it back in the pack take it back to Walmart and get back your money and what will happen now Walmart will have lost money that you you gave to them you take the money back and Walmart will have lost money because they PID the cashier to pay you to I mean to to to uh take the money from you they are also going to pay the customer service people to take the good back from you and upon nothing they have not gained anything so this is why companies believe it is better for them to spend a dollar and save thems $100 then not to spend the $1 and still lose $100 or more than $100 so from what I've said now which company does s quality which which company I'll say anybody that produces any product does complete uh quality assurance anybody that produces a product as long as you produce a product you must do quality assurance because if your product does not meet the user's need please note that thing that I've been saying user's need what is the user's need I go to Walmart I always use the example of a Walmart because everybody knows Walmart if I go to Walmart I need a pen to write and I buy a pen from Walmart I write with the pen and the pen is writing then I will take the pen back that means that pen did not meet my need and when a product does not meet your need you will not pay for it and when you don't pay for a product companies don't get money and that means company has spent money in producing the product at the same time they have not gotten any money back into the company so from my explanation now we realize that every every company does quality assurance be it be it any kind of product that they can produce shoes bags food every every product they must do quality assurance so that they are sure that their product is of good quality that their product can meet the user's need and their product is reliable if you buy a product and it is reliable you always go back to buy that kind of a product again oh I can say ah I bought I bought one water boiler you know the water bers make is so so so so if I want to buy a microwave for example I'm going to buy a microwave that has the same name because the other one that you bought met your need and it will always you know give the company more money because customers will always come back you know what we call repeat business because they have bought something from you before that they not like so I always say one to that I mean even people who sell Gary rice beans and everything they do some some kind of quality assurance you want to make sure that your Gary doesn't look Dairy if your Gary look Dairy who wants to buy it too much bugs and insect in your Gary who wants to buy it I mean there was one African store that I went to here in Houston I mean I wanted to buy Gary I took the Gary so many uh bugs and insects in the Gary I just dropped it nobody wants to buy your product if your product is not good that is why companies try to make sure that their product is good good and buyers will buy it and you can only achieve this through quality assurance okay so I've talked so much about quality assurance but now what do we do we don't test Gary we don't test all those things what we test is software so what is software quality assurance our profession is software quality assurance it is not it is not bicycle quality assurance it is not Gary quality assurance it has to do with software but the procedure I mean the concept is still the same the concept is still the same in software we are trying to make sure that the product or the software is well tested and that product meet the need of the users okay let's look at it every company every company in in this present World uses a computer and once you use a computer you must need some software to run your computer so assuming that now you are you are a you in the mortgage business you in the morgage business let's just take that small example you in the morgage business and you register loan for for customers and you make money through registration of loans and your application that you're using to register loan does not function well it does not function properly that means you will not be able to register loans for customers that means you will not be able to make money that means that person will be out of business if your application does not function properly so you must make sure that your application functions properly so that that application will do what it's supposed to do and it will bring money into your company okay let's talk about the medium stroke big companies in America I mean America is the most developed country in the world and I mean we have the kind of companies that we call medium companies here in America in some countries they are the largest companies and from The Medium companies here in America to the big companies everybody uses software everybody uses application everybody uses computer and once they have this software this software must be tested to make sure that the software meet the need of the user so if you come to this C course you finish this course and you go into the career of a software tester for example you will be your duty will be testing software and why do we need to test software I mean I've mentioned some of the reason why we need to test software so that that software will bring in money into the company most software the thing what the the function of most software is bringing money into the company because that is the medium or that is the media through which money comes into to the company through these applications I'm going to show I mean I me open up some applications and we're going to see what really I mean we can start wondering what is an application what is a software what is a software so we are going to talk about that let's go to okay uh somebody was asking me that what are the various job titles in the profession and I said we're going to talk about it today what are the various job titles of the profession let's go to the next page okay you can see see these are the various job titles of this profession uh normally we're used to I mean a doctor is a doctor a lawyer is a lawyer accountant is an accountant but if you come to this profession there are several titles there are several titles and you know it starts from test analyst qway test engineer systems Q engineer solutions for test specialist QA specialist QA analyst one two three I mean one Q analyst 1 123 is used mostly in United Kingdom you know because I have some students from there that's why I always write it like this but in USA most of the time is SK analyst so the next page I still have some software engineer or sorry test engineer software test analyst testers and kway testers these are all the titles I mean let's count them this these are four here and these are uh 8 9 10 so there are about 10 titles that I mean you can call yourself there are 10 titles that you can call yourself but then it would not be possible to call yourself 10 titles what the best thing to do is to pick one of these titles and stick to that title if you decide to call yourself kway specialist you continue to be a k specialist my own title is kiway analyst and whichever position that I'm working I always call myself K analyst I don't change it so and what is the reason why I always like to tell my students this the reason is that when you start looking for job you know if you are looking for accountant job just put in accountant in the job uh job application uh uh that uh what how do I want to say I mean like monster or Career Builder you know just put in accountant and then you'll find a lot of jobs in accountant accountancy field but in this profession you have to search for job on all these titles hello some people are speaking and I mean it's disturbing the class thank you so you can put your phone on mute if you know you want to talk so that it doesn't disturb us so you can you can you have to search for any of this title and every of this title before you can be sure that you have searched for all the titles and all the jobs out there and they all mean the same if you decide to call yourself QA tester you can also do this job of software test analyst you can do the job of test engineer you can do the job of uh of for example Q test engineer test analyst I mean you can do anyone they all the same they mean all the same they mean all the same there's no difference I mean some tiny differences but doesn't matter I mean it doesn't really matter what those differences are they are all used you can just choose anyone and then you can just start using it I mean once you finish your course and you want to start looking for job so those are the job titles I mean sorry the titles and the job designations so then we have technical writer you can also do the job of a technical writer a technical writer is somebody that writes a manual by the time you come come to this class and pass through the class you will understand how to write a manual ual a technical manual you understand how to write it you understand how to write a manual for software for for a software you understand how to write a manual for software then my next question will be where can you work where can you work I mean the good thing about this profession is that you can work everywhere a doctor can only work in the hospital a nurse can work only on the hospital I've never seen a nurse working in the bank I've never seen a nurse working uh maybe in the manufacturing industry but as QA you can work everywhere you can work in the hospital you can work because everywhere uses application everywhere uses software so you can work even with the government you can work government uses software everybody uses software and as long as there's a software the software must be what must be tested so that is why if you go go into the job market you just type in any of this just type in test for example you see hundreds of thousands of jobs because you can work everywhere you can work in the bank you can I mean name it in the mortgage in the I mean anywhere everywhere you can work in the oil industry every company you can work so it makes the job to be out there it makes the job to be there it is not I mean like you can only work in some sections so that I mean it makes the job to be quickly saturated no and some people are ask me too don't you think everybody is going into it that it will come to a time that there will be no jobs I say no because you are just knowing about it today doesn't mean that it is existing today you are just knowing about it but this has been existing for more than 30 40 50 years as long as computer has been in existence the only thing now is that people are just starting to know about it that it come to you I mean that you are just knowing about it some people knew about it 2 years ago they already in need some people knew about it 4 years ago they already in need and some people don't even have not even heard about it they are going to hear about it next month and they will say ah but I'm just hearing about it so that is just about that it can never be saturated because it is a very very very very very large market and you can work everywhere even there are some countries that they G CR card just because you are a software tester you know that shows how SC software testers still are even though I mean you know you would think they are too many but they are not they're in scarcity they in scarcity so to work you can work everywhere check up uh countries like UK check up countries like uh like uh France check up countries like Republic of Ireland go to their website and check and just click on green card you know work permit and see this kind of uh uh check the kind of uh uh professions that they give green card to from people from anywhere in the world if you're nurse if you're doctor if you're software engineer if you software tester they give you green card so it shows that I mean these jobs I I mean there are not enough people in this profession and they're looking for people so do we have any question at this point up to what I've discussed do we have any question at this point have any question okay so um uh I'm on the next page now and this page says Parts I always like to tell my students uh you know there is there is another live apart from kiway and there are some other things that you can do once you come into kiway you have finished kiway you have started working there are some other directions that you can go we have a school here in a a h a training center here in Houston where you know you can do a lot of all these courses maybe thereafter once you are already in kiway and you want to expand your knowledge you you want to extend your knowledge and you want to I mean move up quickly in your career I mean you can I have you know I've divided them into several parts technical ones and very less technical ones like I mean from kiway you can do business analysis and then you can do SAP uh you know with kiway the best one that goes with kiway is the sap H FICO financials and controlling so you can also do that one then you can do project management and then you know once you have all this knowledge then I mean you will be indispensable in the market you know I mean these are just ways to uh move up and quickly become a manager or quickly become a lead or whatever so then we have another one which is this is a little bit technical but not too much technical you know from kyway you can go to database you can go to I mean these are just I just designed this I mean it's not really for this class today but it's always for my students to advise them once they finish Q on which level they can go I mean depending on their knowledge and their capability and their background and their interest so there are some other ones uh I mean we have a lot of other courses I will show you maybe at the end of uh this presentation those courses that we have in the training center here in Houston okay so what will you learn in this class in this course what will you learn in this course and what is the aim of this class the aim of this class is to give you 3 to 5 years of experience that is the aim of my class the aim of my class is I mean I just say three you know for those people who don't really get it much but the normal one is 5 years so by the time you go through my class your knowledge will be that of a 5e person who has been in qway your knowledge will be like that of somebody that has been in kiway for over 5 years just a minute guys hello hello hello who speaking we can't hear just a minute please just a minute hello so as I was saying I said my class will give you uh 5 years of experience at I mean that means when you finish my class and you sit together with somebody that has 5 years of experience in kiway you and that person will be on the same level so that is the aim of this class and we do a lot of assignments a lot lot lot of assignments practical things practical skills practice and practice and practice you know know until you know we get everything that I'm really teaching in the class and you know once you are able to follow this definitely you achieve that 5 years you know in skill so that when you go out there you are not going out there as entry level if you if you look into the job market you find that the job market says we're looking for somebody with 3 years experience we're looking for somebody with 5 years experience but when you finish this class you will see that I mean my students call me and say oh man I see some job descriptions I mean everything that is in the job description I understand everything because we do everything in the class and we have the Practical knowledge of those things not just learning cramming no we learn and understand we learn and understand and this is one general question that student always ask me are you going to provide materials H my answer to that question is always this there in my class I would say there is no material hello hello yes some people are speaking and you know it's disturbing what I'm saying I I don't think they can really understand what I'm saying they're speaking you know just put your phone on mute I mean if you want to speak so that it doesn't disturb you know the flow of of the class so I always say I don't I I mean in my class there's no material if you're coming to class get yourself a big note like they call it Nigeria or maybe a college block like they call it here get yourself a pen write down everything that I say write down every example that I give this will always make you to understand what we are talking about and if there's anything that you don't understand call me I will re explain and re explain and re explain until you understand it sometimes we might need to redo some lectures if I find out that you you don't understand it and there always exercises exercises and you know practice practice so that through these exercises I will really understand oh these guys I mean these people understand what we are doing and then we can quickly move ahead so it is not that does not mean that I don't give materials but what I do is that I give the materials towards the end of the class when you can read it and understand it not at the beginning that you get confused and believe you me believe you me if you don't even if I send out materials and you don't even read this materials you are good to go once you able to write down most everything that we do in the class you write it down and you understand it it's like I mean I is like you you want to drive a car can you drive a car theoretically I mean with with mouth no when you drive a car with mouth it is different when you now go on the seat and then handle a car what we do in this class we go on the seat and handle a car and once you go on the seat and handle a car nobody can I mean you don't need to study to answer any question on how you drove the car the only thing you need to do is just to continue explaining oh when I did this then I did this when I did this then I did this because we have done practical things on driving a car and exactly some something like that is what we do in this class we make sure that we learn everything that we do practically so when I explain something I show you the Practical when I explain something I show you the Practical and then I give assignments on how to practice it and there is no way through this methodology that you know people will not understand but if it happens that you don't understand I always there I explain and explain until you understand so then what are the prospects of this career both in USA and worldwide I think I've talked about this when I was talking about uh you know where can you work the prospect of this job are everywhere if you call London today you want to work one year in L I mean I have guys that they just go all over the world working one year they're in Dubai another year they're in Japan another year they're in Canada another year they're in Argentina another year they're back to UK I mean you can walk everywhere even you'll be surprised that the language of software testing I mean I lived in Germany for a long time and in Germany they spoke I mean they speak German I mean they still speak German so but you'll be you'll be surprised that the language of software testing in Germany is English people do software testing in Germany in English they do software testing in Switzerland in English Switzerland they speak German and French but the language of computer in the world is English so you can work anywhere you want to work I mean somebody would then ask but I don't have residence to work in UK there is something they call job uh job residence you know just like working per me if you want to work in UK you apply to those companies you do interview they apply for one year feza for you you can work in UK for one year with with that company and then after one year if you want to leave you can live so I mean I'm just saying this to tell us that uh even I have some people in uh I know of one person in a houon here that has gone to Nigeria to work for one year with Chevron as a QA analy you know that that person lives there in Houston but she went to Nigeria for one year to work with Chron and then came back to to us so you I mean you have the flexibility I mean can you imagine you know companies in Nigeria now I mean some people say but do we have kway in Nigeria but they companies in Nigeria use uh they use software I'm talking of the big companies now I'm talking of the bank the financial institutions the the big in uh uh you know manufacturing industry like CB and all those kind of Coca-Cola they use all these things and they have all these things in their company so and they pay their professionals very very very very well very well so then what are the prerequisites of this course what are the prerequisites I would say you're are going to learn almost everything I would say I mean I don't think there's anybody in this age that has not never operated a computer before or has never seen a computer I mean as long as you know how to put on a computer you know how to go into y you know how to write mail and send mail you are good to go for this class that is the only knowledge that we need for this class and then you need a computer if you don't have a computer then you can't come to class that your your computer will be your means of coming to class so you need a computer then you need a phone to call in those are the two things that you need other things will be from my own Blackboard I teach I write on the Blackboard and then you know that's how it goes then what is the difference between my class and other QA classes I always say this because I don't want people to waste their money I have a lot of people in my present I mean I have several classes running I have some people in my class now that they have gone somewhere before to learn this thing and they came back to my class to learn it and you know they went somewhere they didn't understand it until they came to my class and the difference between my class and other classes is that I am in this business so that you can succeed I am not in this business so that I can just make money I'm in this business so that you can succeed so that you can get a good job in this profession so that you know it doesn't even end even after the class you can still call me oh F I don't understand this I don't understand that I mean how should I do this how should I do that I mean I'm always there it doesn't mean that once class ends you cannot call me you can always call me that is no problem about that and then the real difference between my class and other classes is that my class will give you that experience that you need to get into the job market it it will give you the experience as I've said of a 5ye person that has been in keyway or software testing so let's go to the next page okay so then now we I've talked so much about keway yeah I mean we have to test application we have to test application we have to test why I mean I'm sure that still it might not be clear to some people but why do we need to test the application although I've mentioned that I mean we need to test the application so that the application can me the user name but I want to just give some little explanations on if you don't test the the application what can happen what can happen if you don't test the application what can happen if you don't test the application well what can happen I'm sure we have all uh an application that is not well tested can cause debt I mean somebody can say bet why are we using application to drive RIS are we using application to drive a car no but I'm saying that an application that is not well tested can cause death how can this cause death I'll give two examples and then I'm sure that you'll be able to give I mean relate to some other examples of your own my first example will be this we have all been to the hospital or to the clinic whether in anywhere before and you know we have a lot of these machines that they use in the hospital these machines are all electronic machines isn't it I mean we have all seen it and they they run on software there are some software in these machines that run and I want to give an example here here for example somebody goes to the clinic or goes to the hospital and that person is sick and that person say yeah I always have pain in my head that I always have pain on the right side of my head and the doctor says okay go for sray go and do some xray I mean I've looked I couldn't see anything but go and do some xray and we'll check your head and see what is wrong with the head and that person goes into into the X-ray room and goes into this x-ray machine I mean those sray machines are very large and they being run with software and this person goes into the software and goes into the machine and the machine takes the X-ray takes all the reading and brings out a result hello hello hello oh okay I'm still here I don't know yes we are trying to ask some question yeah we are trying I was I was trying to contribute but I couldn't you were just talking I couldn't hear you you know but I can I can hear you I mean that's what that's what I always say that if you want any if you want to ask any question just whether I'm talking or not just ask your question okay yeah because sometimes I always ask is there any question everybody says there's no question so I continue talking but if you want to ask a question just say I first us and then I will stop and then you ask your question okay go ahead please no problem I know I was just trying to contribute to what you're saying that why do we need to test application okay you can make your contribution that's welcome yeah there's a lot of there's a lot of reason why we need to test the application because you can put the company can be at risk it's better to find the effect why the application is being built rather than why the the application is in production because it's going to cost the company a lot of money if the application goes wrong if anything happen that is that is perfectly correct that is perfectly correct and that is one of the major reason why we have to test softw you know I've also mentioned that you know every company is there to make money there is no company that I mean even caras Red Cross they are all charity organizations but still make money isn't it if they don't make money they can't run yeah every company needs money to run so and money must come in and if the channel of money coming in is closed that means money doesn't come in for example uh Walmart has a website where you can go to and buy your product and I'm sure that Walmart website brings in everyday Millions for into WM account millions and assuming that wart wmart website goes down for two days that means one month will lose for that two days if if it brings in let's say 10 million for them in one day that means for that for those two days WM will lose $20 million I mean we talking about big money here and so it pays wart to give you that peut that satisfy us I mean $45 per hour $50 per hour $40 per hour oh we are all jumping up that's great but it pays one man to pay us that money than to lose 20 million yes and that is why software testers are always in demand and you are there 24 hours monitoring the application I mean I'm not saying you be working 24 hours but you always have a job it is not that there's a lawsuit against what it called now United Insurance Company yes for claim I mean for the application I think something that has to do with claim yes so I mean so if your application is not functioning well there will be lawsuit against you and it can make your company to fold up and if any application is not functioning well it comes back to you as a software tester if there's no Law and Order in a country or in a in a city it comes back to the police of the of the St isn't it so and the police of software testing or of or sorry of companies when it comes to application is the software tester or the Q analyst you are the police you are the person that will say the application is functioning well and everybody will say oh it is functioning well you are the person that will say it is not functioning well and they will believe that it's not functioning well so go ahead sir yeah you said in your earlier statement that what's it called that you're not going to give us a reading material yes sir this with this with the quality assurance what I made to understand that you need a constant practice there be anything like um like a software application where someone can constantly practice and two do you give anything like a technical support maybe for some one of your student who at the end of the day that is going on what's it called maybe on a job it can always get back for something like your feedback okay thank you so much for that question H I've I think I've answered a little bit of that question but I will go over it again what I said uh if you understand me very well what I said is that it is not that I don't give I don't give materials but materials are not important materials are not important you don't need the material to learn how to drive a car you need to really go on the seat and drive the car materials is only Theory and my class is not about Theory it's about practical for example you want to prove that you have 5 years experience will it be in theory or in Practical practical in Practical so my class is all about practical it is not about Theory I don't have time to give you a document of 20 pages on the definition that I can give you one sentence two sentences and show you the practic Practical of it and you have the perfect understanding of it some people here in Houston they went to the university here to learn quality assurance it cost them $2,600 and they came back to my class at the end of the day because they had a lot of materials a lot of materials believe you me these materials will not help you I I mean I said it before I have also these materials but I'm going to give you this materials at the end of the course so that when you are reading it it makes a lot of sense to you that is what I'm saying I'm not saying I'm not going to give you material but you know some it is easy to just look this is what I had and this is what works but when you come to my class you have another opinion I've been a teacher from Nigeria even when I finished my secondary school in those days I was a teacher in secondary school you know in those days if you if you have good grades in secondary school you can teach in secondary school before I went to the university I was a teacher I went to the university I didn't do education I didn't do teaching I was still a teacher when I finished my University I was working my normal job I was still teaching because I love teaching and I really understand what people need to learn I understand what you need to learn so that comes back to my my question which is u i mean you say it's going to be practical so you're going to be doing like you know online like you know like what you're doing right now so you're going to be using the the software you using to you know to teach people on you know how to use the software so what are you what what do you have do you have the rational tools or the me which is now HP okay H to answer that question I would say you know normally if you're just Ian there a lot of things out there you know you have Ral yeah yeah I mean the question that you have asked is a very very perfect question that everybody ask me and you know one thing I always say people concentrate more on on automation those tools those tools are nothing I know I know I'm I'm not talking about automation whether manual or automation now but you know whether you're doing manual or you're doing to use a tool no no no no no no no no if you're if you're doing manual you don't use any tool you use a tool no please you don't use any tool what do you use to what do you use to L your defect that is yeah I mean people don't use spreadsheet to do that they use tools okay they use tool to Lo their defect okay if you ask me a question please give me a chance so that I can answer the question okay okay your question is everybody uses tools so are you talking about automation tools or just tools I'm just talking about the tools I mean I'm not talking about automation tools okay so if you if you if you if you use if you use uh ex if you use Excel you are also using a tool a lot of companies you won't believe it that even up to today a lot of companies still use assess I know to log I mean that is a tool yeah I know but that is not it's not an automation tool so that is what I'm trying to explain those are tools they are not automation tools automation tools I mean my class will provide you with merury tools test director win Runner load I mean all those things but I always tell my students don't worry yourself about those tools those tools I mean the way I qualify them is this if you want to go to university or sorry if you want to go to Secondary School you must first of all go to Primary School yeah if you want to write if you want to H read and write you must first of all learn how to read and write automation is about reading and writing automation is not about learning how to read and write you have to know man manual is about reading learning how to read and write I concentrate more on manual so that when it comes to automation what you have learned in manual is just flows and you can automate I mean I taught my students we spent just one hour on learning test director and everybody understood it because they understood exactly what manual testing is all about so that is I you know if you go to some classes some classes will start with you with automation they will run qtp they will run all those rubbish no I spend a lot of time making Mak sure that you can read you can write okay so once you're able to do that believe you me automation is nothing it's just the I mean it's just like using a tool to do what you know how to do manually now in a faster way so that is uh does that answer your question yes okay so I mean it's not that I mean I one more question I'm sorry go ahead you can ask 10 questions 20 question that's why we're here today hello okay so is this going to be like are is this class going to be like are you going to have to like you know how to write a query you know using SQ and all those stuff we are going to learn all those things in this class but we're going to learn those things on our own I have a way of teaching people this that you are going to learn all those things on your own we are going to learn uh four development languages HTML XML JavaScript vbscript and SQL SQL basic and advanced okay so we're going to learn all those things in this class anything that you will need in testing will be given to you anything that you need when you go out there everything that you need will be given to you the things that you will need to get a job and the things that you will need to survive on a job uh going back to one of the questions that uh some of us asked that am I going to offer support or maybe it was you that I asked that question sometimes ago that am I going to provide support you know once uh we finish the class and you're on the job I'll will tell you one secret if you pass through my class the only time you call me would be to say fos how are you doing the only time you would need to call me will be when you say festos uh you know this is just what we doing at work not to call me and say or go into the toilet and hide and start calling me and say oh F oh they gave me this document I don't know what to do with it we will do everything in this class everything real life situations business requirement documents that are of project that are running now currently I will give it to you you are going to work on everything we're going to do everything as if we are working in that company and we're doing a project and believe you me if you go through all this what will shake you nothing yeah Mr yes ma'am you said earlier yes ma'am the assignment is it through the c or what material are we going to use uh the the the assignment will normally be write this and write that I mean you can use Word document you can use whatever just send it to me just like you send email yeah I mean that that is the those kind of assignments I mean when I give you assignments then you just write the assignment and then you send it to me I will go through your assignment and then I will give you some feedback yeah and there's one thing I I always do also in my class I always hold group discussion I divide the class into two I mean if there if there are for example six people in the class I divide them into two groups and I send out questions every week for the for each group to meet and discuss those questions those are interview questions I don't want to wait until the end of the class before we now start saying interview questions I want to make sure that you are conversant with those questions you are confident with those questions you have the answers to those questions and even if you're sleeping somebody wakes you up you'll be able to give answers to those questions so we do this on and on on and on until the end of the class although I don't start it almost immediately I wait for maybe 2 weeks week or 3 weeks when I'm sure that we have learned something tangible and then I can start you know we can start the group discussion so this is also one I mean it takes it takes time but at the end of the day we will really see what we have done with our time any other question before I go ahead okay I want to quickly as he me yes go ahead please pleas oh I'm sorry I didn't know I was muted okay two questions so what you're saying is that I okay today I went to the store and I went to I was trying to get quality assurance books but I was I was looking for quality assurance for dummies but I got quality control so it's what's the difference and also are you saying that I'm excited about the class it's really because of your teaching ability but are you saying that I don't need to go to do another degree or go for a community college or something like that that this is just going to be sufficient for me uh thank you man for that question some people went to the Community College here in Houston they are still in my class so you know I mean we are all from Nigeria we see how we I mean we learned those things in Nigeria people were learning automobile engineering they were drawing automobile engineering or sheet of paper how can you know how to repair a car when it is only draw and label and you have never seen that thing before I mean that is that is the kind of system that we're used to reading and reading and reading and not really practical iing what we have read and that is why sometimes we find out that somebody that just went to a technical college for example in US is better than an engineer in Nigeria because that person has seen it all he has seen all the instruments has seen everything and that is the approach that I'm using for this class we're going to deal you don't need any textbook you don't need any textbook and you don't need Ed textbook you can read whatever online you can I mean even reading online sometimes because I see some things online that they are confusing they not right and I always tell my student you know because anybody can write anything online and you can read it I always tell my students this is not correct and that is not the way it is because I know how it is and I know what it is so you know I don't want to discourage us that don't you know don't read materials or don't do this or don't do that but you know as the class goes on you yourself will now adjust yourself and look do I really need any material with all this no you don't if any material is really really necessary I will send it out to you read this in addition to what I've given to you read this in addition to what I've given to you read this in addition to what I've given given to you and that will just be sufficient for the class that will be sufficient for getting a job and that will be sufficient for you know staying on the job and really understanding what you doing on the job okay finally what's the what's the difference between quality control and quality assurance okay I me okay quality control is part of quality assurance quality assurance is like you know when you are talking about education education starts from kindergarten and ends at maybe University but when I say I want to go and study education at the University educ that education is part of the whole education isn't it so that is how it is quality control is a measure is one of those measures used to achieve a good quality assurance is one testing is also one of them testing is one of the is one of the measures to achieve a good quality assurance quality control is also one of the measures to achieve quality assurance okay so we are going to talk about quality control quality assurance testing in the class do we still have any other question okay so I was talking about uh I was talking about please if you have any question anytime just talk and then I will stop and then you can ask your question so I was I was talking about uh going Somebody went to the hospital and went through a machine that has a software there and I was trying to say that assuming that this machine is not functioning well and this machine shows in the sray result that somebody this guy has a stone in the head assuming that the the S3 machine is not functioning well and the S3 machine shows that this guy has a stone in the head I'm 100% sure that this guy will go through an operation because they I mean the the doctor will concentrate more on the xray result than on the head the doctor will say but I mean the the xray shows that there's a stone here on the right side of the head and we have to remove that stone until they will open the head before they will see that there's no stone there and then that person might lose his life I mean during that operation and what will be the cost of this the cost of this will be a software in a in a in a uh clinical instrument that is not functioning well so this is when a software in an instrument is not functioning well this is just one of the things that can come out of it another example is this that can make somebody to lose life have you ever wondered that I mean when you are driving your car who passes the lights who makes the lights green red or yellow or whatever who makes it is a software that is running some somewhere in a location assuming that the software malfunctions and passes left and right at the same time they will collide accident will happen and they might die from that accident most of the time we drive cars once it is green I just move on I don't care because I believe in the in the in the traffic light that it would not make a mistake but it can happen that the traffic light can make a mistake and left and right can be passed at the same time and they will collide with each other so these are just some of the things that can happen when an application in is not functioning as it is supposed to function and if you look at my screen here I have some examples I mean just some few examples out of the millions and millions of examples that are out there the first one I have here is telephone outage in California in 1991 was caused by a software defect there was something that happened to to some years ago that and application credited almost one uh 1 million people H sorry 800 and something uh people with a billion each almost a billion the application credited those 800 and something people with almost a billion each you know just for nothing and this was traced back to an error in the application so uh the next one that I have here is no charge for distance call I will just quickly give an example of Nigeria in this one that was a time and I'm sure maybe some of us experienced it that you know my brother called me from Nigeria normally when he calls me he calls me only just for one minute oh my brother call me back call me back you know this day he called me and he was talking on the phone talking talking talking and I said what what is the problem what is happening where are you calling from he said I'm talking on my cell phone I mean you are going to incur so much Bill he said brother don't worry just I I mean just let us keep on talking what happened he said MTN is not charging for international calls so the everybody started calling everybody and said oh if you have anybody all over the world anywhere outside Nigeria please start calling that person and this went on for almost 4 weeks before MTM realized that they have lost trillion of money and this was due to their to their to their software billing application that was not functioning and was not recording out calls that were going outside the country I mean if you call within Nigeria it charges you but if you call any International 00 it doesn't charge you so I mean from this we can see what can happen when an application is not functioning well it can cause death it can cause a company to close down it can cause a company to I mean it can cause a lot lot lot of damage so likewise this other ones here that was also a company in us that for 4 weeks it did not charge his 400,000 customers for any long distance call that they made the application of the of the telecommunication company did not charge 400,000 customer this is here in US and this is the most advanced country in the world and most of these examples that I have here are things that are happening in in us so if software have been tested properly every time well in us and all these things are still happening can you imagine what happens in maybe like third world countries where I mean you know it will not be tested as much as I mean people are really doing it here for example so and then the next Point says exorbitant electric bills in Illinois I mean this also happened some years ago that some people just got time seven of their electric bills if you get $100 every month he just gave $700 and people started complaining and they found out that it was the application that was just multiplying everybody's bill by seven you know so and then one of my students gave this mistake made by DHL due to software error this this example is from one of my students uh he said he he sent he sent uh some package to Nigeria and he paid I me through DHL and he paid cash and then after 3 months he got a letter from DHL that he should pay $75 for the package that he sent to Nigeria then he said but when I sent this package I paid for it and I although I got a receipt but it's 3 months ago and I can't I mean I can't find the receipt again since the person from Nigeria called me that he got the package I threw the receipt away they said but our record shows that you have not paid $75 and you have to pay and my student had to pay again because there's no way you can prove that you have paid because the application shows that you have not paid and why is this because there is an error in the application that erased what my student paid and what will be the effect of this for DHL definitely my student will never go to DHL again definitely anybody that he meets he will tell them please don't go to DHL I mean they are Rogues if you send anything through them they want you to come and pay again you know and likewise one of my students also from Germany said one day he received a letter from DHL saying that he has to pay about 50 and he said I didn't even send anything so how come that you mean you are sending me a bill and then he went to DHL and asked them can you provide me with the details of the of the package that I sent and they look for the package and look for the package the details and they didn't find it and then they said Okay that was a mistake from our application so I mean we can see you know when an application is not functioning well what can happen a lot lot lot of things can happen and why do I always explain this to my students or to people when they come to ker day I like to explain this so that you know what you are dealing with you know the importance of your job you know the importance of your duty and you know the importance of your of your profession a doctor knows the importance of his or profession a doctor that has not eaten for one day he sits down to eat and there's an emergency that rings and says somebody is dying he will leave his food he will jump up and go go and attend to this to the patient because he understands the importance of his job so but if you don't understand the importance of your job if you don't know how Grievous what can happen you will do a wish-wash job you will not do a good job because then you think you know I mean let me just leave it like that I mean whatever happens but if you know that if you if you don't do a good job somebody might lose his life if you don't do a good job a company might lose even million they might lose even 20 million through your mistake or negligence then you always make sure that you always do a good job you always make sure that you always do a good job so what is your duty your duty will be to test applications and what is an application for example I just let let me just make an example of uh uh yaho to show you what an application is okay now you okay this is uh this is y web page and this is called an application applic this is a web-based application why do we call it a webbased application I'm still going to mention this in the class we call it a web based application because you have to be on the internet you have to open your internet browser before you can access this application so that is why we call it a web based application a window based application is like your Microsoft uh word your Microsoft Excel your Microsoft Access because you don't need to go on internet because before you can use Microsoft Word this is called a Windows based application a window based application but this one that you have on my screen now is called a web based application okay so what will be your duty your duty will be for example if you are testing a web- based application to test this website that is I mean this page for example that it is functioning as it is supposed to function and how is it supposed to function it is supposed to function in the way that if you click on something that thing is supposed to open up if you click on it and it doesn't open up that means that link is is not functioning hello hello yeah Mr yes ma'am applic what that because I don't see that on your screen okay I said what I have now on my screen is called a web based application but I mean don't worry about this because we are going to talk about this in detail in the class I'm just trying to give you know just some few examples there and I just want to show you for example what you will be doing just for example you know and so I I click on this link and then the link open up and it shows that that link is functioning so I'm going to uh go back now go back to the web page of yah uh this is yaah web page so you can see there a lot of things you can do on this screen you can click on this you can click on any of this link so this how to test this application is to make sure that all these links are functioning I mean it is more than that but that is just the basic of it to make sure that if you click on this page picture the picture opens up if you go on mail your mail opens up to sign in for mail opens up if it doesn't open up then that means you can't really use this app I mean that link is not functioning so there's one thing that I always show my students you know even if they come for the first time there's always one thing that I always show them and I always say there's somebody that builds a house there's somebody that makes sure that the house is is is uh okay to live in you as a software tester or QA analyst your duty is to make sure that the house is conducive to live in there is somebody that is called a builder that builds the house and you are going to check everything that the Builder has built to make sure that what he has buil is what is right and conducive to living so where am I going this for example is the application that you'll be testing but somebody has to write this application and the person who's going to write this application is called a developer and what how will a developer write this application is it going to be painting it just putting the picture here like this no a developer will write codes and once he write code the code will come out in this way all these things that you're seeing on on my screen will be coded and it will come out in this way and you know I always like to show my students for the first time when they come the code behind every application in Nigeria we always say behind every successful man there's always a woman so we want to see the woman now behind this application so you go on view you go on source and then you can see the code that the developer wrote for this page of yaho so let's I click on allow and then you can see the code so this is the code that the developer will write what you are seeing now on my screen I'm going to move it up and down this this is the code that the developer will write and once the developer writes this code it comes out in this way they don't look they don't look like each other I mean they look very very different from each other but we remember something in Nigeria that they call metamorphosis the changing in state of something to another state a a I think I remember in my biology class that uh a magot changes to fly isn't it yes if I'm correct and a caterpillar changes to Butterfly so we might wonder how can this code change to that picture I mean a caterpillar changes to Butterfly a caterpillar is not very ugly just like a magot but changes to a very beautiful thing like a butterfly so exactly that if you think that way then you always believe that everything is possible so when the developer write this code then the code changes to this application so once uh you know and then you can see the line of code that developer has written so long so much you know I mean and this is just a page of the application this is just a page of the application and you can see I mean I'm not even up to the one quarter of that page and you can see how large and enormous this codes are I mean the lines of code I mean I'm sure it will run to thousands of lines thousands of lines you know that a developer will write just for one code H just for one page of you know this kind of application like ya uh application so but your own Duty will be testing this beautiful application and not testing that code sometimes you could always test code I'm going to teach us in this class how to test code you know we're going that's unit testing right yes sir we are going to do some some not really the deep deep unit testing we're going to do the very very important things that was a project that I did on XML XML you know XML is a programming language and there was a testing that I did on only XML and I'm going to show that uh that project in the class we're going to run over it and see how I did it and you know that is just practically also like uh you know unit texting or we call it white box texting because you are testing just the codes and not the application although later you know you have to test the code and then test the application do we have any question at this point no okay so let me go back to okay so I've talked about your duty your duty will be testing the application to make sure that the application is functioning as it is supposed to function make sure that the application is functioning as it's supposed to function how is Y Mail supposed to function yah mail is supposed to function in such a way that when somebody puts in his valid username and valid password it should open up open if for example I put my valid username I put my valid password for example and it doesn't open up that means something is wrong with yaho for example okay and I click sign in if it doesn't open that means something is happening you know to that application but I mean I just somehow I put a wrong password so that it will not open the requir if the requirement Sayer that means you have to use yes I mean it depends on what the requirement says you know that you should use I mean that will be when you are really testing okay yeah I mean that is when you're testing if you're not really testing you're just trying to see what you know for example any application that logs in that logs you in as long as you have a valid that is the key valid username valid password the application must log you in must log in yeah I'm not saying I'm not saying as long as you have a username and password you can have a username and password and it's no more valid but as long as you have a valid username valid password the application must log you in most of the time when I get to work I mean in my career it has happened several times that the application would not log me in although my username and password is valid but it will not log me in that means there's a problem with that application and the IT people will have to come and set the you know the username and password again and then try to set you know everything again and then I will be able to access the application but assuming if I get to work in the morning 9:00 and I can't go into my computer and the IT people are very busy they can't come and set it until 12:00 that means I will have to just sit down and drink coffee till 12 because I can't ask access my [Music] computer so uh it is really really and so what I've just done here is just one of those things that you'll be doing when you are testing an application it is a very simple thing it is a very very simple thing the only thing is that in the class we now go deeper and learn the methodologies of testing the methodologies of testing that you will be well well grounded in it well grounded in it so then uh I have all these things here just to I mean I've talked about this but I always have it just to give some more insight about you know people that don't really have any knowledge about it or whatever I mean so I mean what is a software a software is an application that runs in a hardware my computer that I'm knocking now that you can hear this is my laptop the plastic the everything that is what is called the hardware but the software that is running in it like yah mail like your Microsoft Office like you know Excel assets and all those kind of stuff and all those other application that you use those ones are called your software and most of the time sometimes we also test Hardware but most of the time we test soft software most of the time I would say maybe 99% of the time we test software not Hardware but sometimes I mean in my carrier too I've tested Hardware so I mean once you know how to test methology methodology of testing is always the same it's always the same and so what is an application application is the same
