Seven very different plants, one connected loop. Each story walks the LeanOS cycle step by step — audit, AI-flagged defects, fix-plans, A3 root cause, verified kaizen savings, standards, recognition — and ends with the numbers that matter on the floor: safety, quality, delivery, cost, morale.
Paper checklists and rising rejections — now operators audit on their phones, AI flags the defect, and A3s make every fix stick.
Two days of audit prep and quality data everywhere — now one hash-chained, photo-backed log turns the ISO audit into a walk-through.
Kaizen ideas died on sticky notes — now every improvement is tracked to verified dollars, with a leaderboard driving the whole floor.
Hygiene audits on paper and a foreign-matter complaint that kept coming back — now HACCP walks run on phones and the A3 found the sieve nobody checked.
A deviation backlog and data-integrity findings — now line clearances are dual-signed on phones and right-first-time hit 99%.
Scrap firefighting and ideas that died in translation — now the black-specks A3 found the regrind problem and the ledger shows $210k a year.
Clipboard sanitation logs and a recurring Listeria swab near packing — now hygiene rounds run on phones, and the A3 found the drain nobody had opened in years.
