A practical digital ebook for production supervisors who need to cut repeat breakdown minutes by 50% and make the 90% OEE gap actionable without blaming operators or accepting maintenance guesswork. You will learn how to build one trusted downtime baseline, rank recurring losses by verified production minutes, and separate a true repair from a temporary reset. The ebook shows how to turn failure codes, timestamps, shift handoffs, and corrective action checks into a repeatable operating routine. Across seven focused chapters, you will move from disputed downtime claims to evidence-based priorities, stronger repairs, and daily control that helps keep improvements in place. You will also learn how to use the Repeat Breakdown Traffic Light to distinguish verified causes, temporary containment, and unresolved patterns. Read it digitally at your own pace and apply the methods directly during daily reviews, maintenance discussions, and shift handoffs.
