Acceptance Testing Written into a Statement of Work
Acceptance testing in a statement of work requires explicit pass-fail criteria, calibrated test fixtures, statistical sampling rules, and milestone payment locks.
Non-Recurring Engineering Milestones
Meaning
Contractual payment stages tied to the completion of specific research, development, or prototyping phases govern the compensation of engineering teams. Passing non-recurring engineering milestones triggers the release of development funds and signals that the project is ready for the next phase. These events verify that the engineering partner has satisfied the technical criteria agreed upon at the start of the project.
Contractual Delivery
Phase payments depend on the submission of verified designs, working prototypes, or test reports to the customer. When these deliverables are delayed, the program’s timeline slips and payment schedules are put on hold. This structured approach manages development risk.
Risk Allocation
Splitting the development process into several steps protects the buyer from paying the full amount before the work is done. It also provides the developer with consistent cash flow to fund the project’s progress. This balance of payments supports collaborative development efforts.
Hardware Progression
Progressing from early boards to the final version requires completing several intermediate verification stages. Each step requires testing and validation of the hardware to prove it meets the functional specifications before starting the next phase. This sequence ensures that any design flaws are found and corrected before the expensive tooling and production stages begin.
