Dashboard
Core production inputs
Shared model: Demand + time + count + defects + costs -> takt, OEE, sigma, COPQ
Dashboard notes
Takt compares customer demand to available time, while OEE shows how much of that time actually converted into good production.
Sigma and DPMO translate defect performance into a quality capability view. COPQ converts that same quality picture into business impact.
The most useful signal is often the linkage between metrics: poor OEE can drive takt gaps, while poor sigma can drive COPQ even when flow looks acceptable.
