The main point
A useful trial tests the hardest normal condition and records measurable results. A short demonstration with ideal samples cannot prove sustained production capability.

1. Prepare representative materials
Use normal production product and packaging. This should be recorded in the customer requirement so it can be tested rather than assumed.
- Use normal production product and packaging
- Include dimensional and batch variation
- Send enough material for setup, running and repeated checks
2. Agree the test
Define target output and duration. This should be recorded in the customer requirement so it can be tested rather than assumed.
- Define target output and duration
- List measurements and pass criteria
- Identify the hardest product and format
3. Record the run
Capture settings, speed and utilities. This should be recorded in the customer requirement so it can be tested rather than assumed.
- Capture settings, speed and utilities
- Record every reject and intervention
- Take samples from the start, middle and end
4. Close the evidence gap
List unresolved risks. This should be recorded in the customer requirement so it can be tested rather than assumed.
- List unresolved risks
- Repeat any changed condition
- Confirm what will be retested at FAT or SAT
Customer comparison table
| Weak trial | Stronger trial |
|---|---|
| One easy pack | Minimum, maximum and hardest pack |
| Visual judgement | Measured weight, torque, position, seal or scan |
| Short burst at peak speed | Representative sustained run |
| No fault record | Timed record of stops, interventions and rejects |
