Worksheet 54. Rolled Throughput Yield Analysis

RTY Capability (potential)

RTY Actual

Actual-Potential Gap

Project RTY Goal

Things to consider:
• How large are the gaps among the actual RTY, the capability RTY, and the project’s
goal RTY?
• Does actual process performance indicate a need for a breakthrough project?
• Would we need a breakthrough project if we operated up to capability?
• The RTY cannot be better than the lowest yield for all product features or process
steps. Use this fact to help allocate project resources. For example, would applying
SPC to a subset of CTx’s achieve the project’s goals at lower cost?
