PROCESS CAPABILITY
Master Cpk Analysis & Interpretation
📋 Your Challenge
- Analyze process data and specification limits
- Calculate or interpret Cpk values
- Determine if the process is capable
- Recommend the right corrective action
- Visualize where the process distribution falls
Cpk = min[(X̄ - LSL) / 3σ, (USL - X̄) / 3σ]
Cpk ≥ 1.33 → Capable (good)
Cpk = 1.00 → Marginal (3σ quality)
Cpk < 1.00 → Not Capable (problem!)
Scoring: +10 per correct | +3 streak bonus | +5 speed bonus (under 15s)
