Monitor production and implement process improvements

Production reported a 10% drop in throughput last week and wants immediate corrective actions. Rebuild the daily run‑rate sheet for Line 4 from the last 30 days, calculate yield losses, and itemize stops longer than 15 minutes with associated operator and shift. Send the findings to Claire, the Plant Manager, first for her operational read, then to Diego in Continuous Improvement for root‑cause assignment, due by Monday start of shift — confirm Claire's note is attached.

Before I send this to Plant and CI, make the data point to where decisions are made. Put the top three causes of lost throughput in plain English on the first page, show the time‑of‑day heatmap so Claire can see shift effects, and flag any maintenance orders that sat open longer than 24 hours that Diego should prioritize.

The night shift has five stoppages averaging 20 minutes on Line 4 over the last week, and supervisors claim they logged properly but maintenance says no work orders existed. I'm concerned about either record‑keeping, unlogged operator fixes, or deliberate underreporting. What diagnostics should I run to determine whether this is a logging problem, a maintenance backlog, or a governance failure before I escalate to Claire and Diego?

Across months we keep fixing the same five stoppage causes and it still recurs, costing two shifts a week. We waste time firefighting and lose credibility with Production. Which habit should we change — how we escalate, how we close work orders, or who owns long‑term fixes — and what one governance change will stop the same incidents returning?
