Prepreg Out Time Risk with out-time defect severity rating of 4 score: a worked example
This worked example runs the prepreg out time risk numbers for a tougher week than the baseline: out-time defect severity rating of 4 score instead of the typical 8 score. Estimate risk priority from prepreg out-time exposure during thaw, cutting, kitting, or layup.
The inputs for this scenario
- Out-time defect severity rating: 4 score (the input this scenario stresses; the baseline uses 8)
- Out-time exposure occurrence rating: 3 score (held at the documented default)
- Out-time detection difficulty rating: 5 score (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Prepreg Out Time Risk = out-time severity score × out-time occurrence score × out-time detection difficulty score.
- Prepreg out time risk score works out to 3.9 score at these inputs, and this is the headline figure for the scenario.
- out-time severity score works out to 4 score at these inputs.
- out-time occurrence score works out to 3 score at these inputs.
- out-time detection difficulty score works out to 5 score at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where out-time defect severity rating sits at 8 score and the headline result is 5.5 score, this scenario comes in 29.09% below the baseline at 3.9 score.
- Use it during PFMEA, control-plan reviews, or any time you are deciding whether out-time tracking needs tighter controls. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.
Results at a glance
- Prepreg out time risk score: 3.9 score (headline result)
- out-time severity score: 4 score
