How to use First-Pass & Rolled Throughput Yield
- Load the worked example to see the required input format.
- Measure first-pass performance and combine stage yields across a process. Use consistent units, periods and definitions.
- Select Calculate, review the assumptions and export the result for your project evidence.
Formula and method
FPY = first-pass good units / input units; RTY = product of all stage first-pass yields.
Interpretation and assumptions
Use first-pass yields, excluding recovered rework. The product describes sequential stages with compatible flow definitions. Do not average the stage yields.
Results support professional judgement. They are not a certification of process stability, a financial commitment or a substitute for study design.
Frequently asked questions
How do I use the first-pass & rolled throughput yield?
Measure first-pass performance and combine stage yields across a process. Load the example first, then replace all inputs with consistent process data and select Calculate. FPY = first-pass good units / input units; RTY = product of all stage first-pass yields.
What assumptions matter for first-pass & rolled throughput yield?
Use first-pass yields, excluding recovered rework. The product describes sequential stages with compatible flow definitions. Do not average the stage yields.
