{"id":"oee-quality","model_id":"Quality Rate","name":"OEE Quality Rate","summary":"Quality rate is one of three elements of Overall Equipment Effectiveness (OEE), a Total Productive Maintenance (TPM) measure of how effectively equipment is used. It expresses losses due to scrap and rework as a percentage of total parts run. OEE multiplies availability, performance, and quality rates.","study_notes":["OEE = Availability Rate × Performance Rate × Quality Rate.","Example: 0.90 × 0.95 × 0.99 = 84.6% OEE.","OEE typically focuses on six major losses: failures, adjustments, minor stoppages, reduced operating speeds, scrap, and rework.","Some companies add other measures judged important to their business."],"safety_notes":[],"sources":[{"url":"https://www.lean.org/lexicon-terms/overall-equipment-effectiveness/","title":"Overall Equipment Effectiveness - Lean Enterprise Institute","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":2,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"operational","spec":{"kind":"metric","origin":"Total Productive Maintenance (TPM)","related":["oee"]},"url":"https://machineschema.com/operational/oee-quality","license":"https://creativecommons.org/licenses/by/4.0/"}
