01
Problem
Manufacturing test software used for product acceptance required evidence that test sequences, data recording, and release-controlled files behaved as intended.
02
Constraints
- Software controlled product acceptance decisions.
- Version and configuration traceability had to be maintained.
- Access control and record retention affected data integrity.
- Regression risk existed when test sequences changed.
03
Engineering Decisions
- Mapped software behavior to test requirements and acceptance criteria.
- Used known-good and known-bad conditions to challenge test logic.
- Controlled release files through version management.
- Verified record creation, storage, and retrieval.
04
Validation
- Executed functional verification of test sequence behavior.
- Confirmed data logging and access controls.
- Reviewed release version and configuration records.
05
Risk & Mitigation
- Uncontrolled software changes could invalidate acceptance results; mitigated through version control.
- Incorrect pass/fail logic could release defective product; mitigated with challenge conditions.
- Incomplete records could weaken investigations; mitigated with data-retention verification.
06
Outcome
The manufacturing test software release was supported by traceable validation evidence and controlled configuration management.
