How to use it

Work from the top. Safety and people come first because they set the trust you need for everything else. Tick items as you complete them and mark the ones you cannot answer so you can ask for help. Keep a notes file next to the list with what you heard and from whom, since patterns across conversations matter more than any single comment.

How the list is organized

The groups follow the order in which most new leaders build their picture: first, what could hurt people or stop the plant; second, who does the work; third, who depends on the plant; fourth, what the numbers say; fifth, how data reaches decision makers; and finally what you will change first. Critical items are the ones that, if skipped, usually cause surprises later.

Listen first on every shift, including nights and weekends.
Cross-check reported KPIs with the floor.
Do not announce a large change before day 60.

Reading your progress

By day 30 you should have toured every area, met every direct report and know the top customer and safety issues. By day 60 you should be able to explain the plant's performance and its causes. By day 90 you should have a short plan with owners that the team recognizes as its own. If something is still unclear by day 90, name it openly.

Common mistakes

New managers often start fixing too quickly, rely only on reports in the office, or ignore the night shift. Another mistake is trusting dashboards without asking how the numbers are produced. Ask who enters the data, when and why, before deciding what the data says.

Frequently Asked Questions

Should I make changes in the first 90 days?

Fix safety hazards and clear customer failures at once. Hold off on structural changes until you understand the causes. Quick, visible wins that the team asked for build credibility for larger changes later.

How do I handle a plant with weak data?

Say so openly, pick a few measures you can trust, such as safety, delivery and scrap, and verify them on the floor. Improve the data in parallel, since decisions made on unreliable numbers can do harm.

How often should I be on the floor?

Daily in the first month, on every shift at least once. After that, keep a regular routine. Time on the floor teaches you how work really flows and signals what you care about.

Can I use this for a new operations director role?

Yes, with adjustments. The groups are the same, but you would add reviews of each site and of the shared services that support them, and spread the schedule over more time.

If reports take days to assemble, Netray can help build a read-only view over your ERP so a new leader can see delivery, scrap and inventory trends from the first week.
