Masterclass Capability Matrix (Static Reference)
| Scenario | Cp | Cpk | Std Dev (σ) | Interpretation | Conclusion |
|---|---|---|---|---|---|
| Process centered, capable | 1.33 | 1.33 | 0.50 | Process spread fits well within specifications, mean exactly centered | Process is capable and well-centered; variation controlled |
| Process centered, borderline | 1.00 | 1.00 | 0.67 | Spread just fits specifications, mean centered | Process just meets specs, minimal margin for error |
| Process spread too large | 0.75 | 0.75 | 0.89 | Spread exceeds specs, mean centered | Process not capable; variation reduction needed |
| Process off-center, capable | 1.33 | 1.00 | 0.50 | Good spread, but mean shifted closer to one spec limit | Potential capable, but centering needs improvement |
| Process off-center, borderline | 1.00 | 0.67 | 0.67 | Spread fits specs but mean significantly off-center | Process borderline due to poor centering |
| Process off-center, not capable | 0.75 | 0.40 | 0.89 | Spread too large and mean off-center | Process not capable; both variation and centering need improvement |
| High capability, well-centered | 2.00 | 1.98 | 0.33 | Very tight spread, mean almost perfect center | High capability process, very stable and consistent |
| High capability, poorly centered | 2.00 | 1.00 | 0.33 | Tight spread, but mean strongly shifted | Process spread is good, but poor centering reduces actual capability |
| Low Cp, any Cpk | 0.50 | 0.45 | 1.33 | Wide spread, likely poor centering | Process variability too high; fundamentally not capable |
