Turn raw production data into the quality KPIs that matter — First Pass Yield and Rolled Throughput Yield, DPMO and Six Sigma level, scrap and rework rates, supplier PPM, on-time delivery, returns/complaints and Cost of Poor Quality. Each metric is scored good / watch / poor against a target, with an optional multi-period trend. Aligned to Six Sigma DPMO–sigma conversion and ISO 9001 clause 9.1. Word, CSV & print.
ℹ️ Sigma level is derived from DPMO using the standard Six Sigma conversion Z = NORMSINV(1 − DPMO/1,000,000) + 1.5 (the 1.5σ long-term shift); 6σ ≈ 3.4 DPMO, 3σ ≈ 66,807 DPMO. KPI thresholds (good / watch / poor) are common industry defaults — set your own targets from your quality objectives. Monitoring, measurement, analysis and evaluation of quality performance is required by ISO 9001:2015 clause 9.1. This is a calculation aid, not a substitute for a validated quality management system.
