Define routing for manufacturing

We need routings ready for next week's job schedule. Send the new routing draft to Lin in process engineering and then to Javier on the shop floor for practical sign-off, due by Wednesday noon; verify cycle times, tooling requirements, and work center capacity before routing is issued.

Before I hand this routing to production, make it easy to approve: show total takt time up front, list critical operations and required fixtures, call out any operations that need overtime or external services, and flag steps where the standard time differs from historical averages.

The updated routing I received increases cycle time by 30% without adding operations. I own routings and capacity plans; Lin authored the routing and shop floor supervisors will be blamed if schedules slip. I'm not sure whether times are inflated to pad capacity or if setup steps were merged. What's the best way to validate the extra time quickly and who should I pull in to avoid a schedule hit?

Over the past quarters routings are repeatedly changed late, causing downtime and overtime. I coordinate routings, process engineering drives changes, and supervisors push back at the last minute. Which recurring habit causes the most rework — ignoring operator feedback, skipping pilot runs, or approving without capacity checks — and what single change will cut these emergencies most effectively?
