Repair records become more valuable when they include comparison data.
Before Repair
Record:
- original symptom;
- fault conditions;
- test results;
- operating state.
After Repair
Record:
- repaired component;
- verification results;
- remaining symptoms.
Why Comparison Matters
Without before-and-after information, it is difficult to determine whether the repair changed the actual problem.
Conclusion
Diagnostic records should show the repair process, not only the final replacement part.
