Service Metrics
Clearly defined KPIs (uptime %, MTTR, response windows) with formulas and measurement windows so both parties read the same metric.
A focused addendum reduces ambiguity about measurable service commitments, limits dispute risk, and aligns expectations across legal, technical, and vendor teams under enforceable terms.
Different teams and stakeholders play distinct roles when preparing and executing a Business SLA Addendum.
Assign clear ownership for drafting, review, and final signature to reduce cycles and prevent approval bottlenecks.
The General Counsel or another authorized corporate officer typically signs on behalf of the customer to bind corporate commitments; include title, signing authority, and corporate resolution reference when required.
A vendor's VP or director-level representative with delegated contracting authority signs for the provider; ensure the signer has express authority documented in internal delegation records.
Clearly defined KPIs (uptime %, MTTR, response windows) with formulas and measurement windows so both parties read the same metric.
Source of truth (vendor monitoring, third-party reports) plus reporting cadence and data retention to support audits and credits.
Financial credits, termination rights, or corrective action plans tied to metric breaches and described with calculation examples.
Force majeure, scheduled maintenance, customer-caused outages, and other carve-outs that suspend SLA obligations when applicable.
Contact hierarchy, response SLAs for escalations, and mandatory review timelines for repeated failures.
Change control, amendment process, dispute resolution, and review intervals to keep the addendum current and enforceable.
