Why It Matters
A well-run FAT is a working session, not a ceremony. It gives the customer and integrator a shared record of what the line can do and what remains to be closed.
Key Data Points
| Topic | Planning Note |
|---|---|
| FAT input | Approved samples, recipes and acceptance criteria |
| Test focus | Speed, quality, safety and recovery behavior |
| Closeout output | Punch list, evidence and release decision |
Agree on the test before the test
Acceptance criteria should describe good product, tolerances, speeds, changeovers and safety checks in language both teams can use.
Bring real production conditions
Representative samples and packaging materials reveal issues that a clean demonstration product can hide.
Test recovery, not only the happy path
A line that restarts clearly after a stop is more valuable than one that only looks fast during a perfect run.
Capture evidence as you go
Photos, measured results and issue owners turn the FAT into a useful project record.
Carry the learning into commissioning
The final FAT record should become the installation checklist, training agenda and service baseline.
