Scope of Work
Define prototype objectives, specific features to be built, deliverable formats, and measurable acceptance criteria to avoid scope creep and enable objective validation.
A clear prototyping agreement reduces scope disputes, speeds decision-making, and defines acceptance criteria so teams can iterate confidently while preserving legal rights.
Typical participants include internal project sponsors, external contractors or agencies, product managers, and legal counsel who review terms before execution.
The agreement serves operational, legal, and financial functions and should be shared with stakeholders responsible for delivery and acceptance.
Head of Product or Program Manager authorized to approve scope and sign on behalf of the client. This individual accepts deliverables, approves change orders, and is the point of contact for acceptance testing and payment approvals.
Authorized officer or project lead for the contractor who commits to resource allocation, delivery timelines, warranties, and intellectual property assignments. This signer accepts liability limits and agrees to the contract's dispute resolution process.
Define prototype objectives, specific features to be built, deliverable formats, and measurable acceptance criteria to avoid scope creep and enable objective validation.

Specify fees, payment schedule, invoicing details, and late-payment remedies. Include change-order pricing methodology for out-of-scope requests.
State ownership of prototype outputs, licensing rights for code and designs, and obligations for pre-existing IP retained by each party.
Provide objective tests, time windows for client review, defect remediation process, and final acceptance sign-off procedures.
Set termination rights, notice periods, refund or wind-down obligations, and caps/exclusions for liability, including warranty disclaimers where appropriate.
