Three-day stop, six-week coupling

A planner in a freight workshop once showed us a stop that began on a Friday night because a customer gate would be shut. The coupling they needed had a promise date in the following month. Everyone in the room already knew. Nobody had drawn the two facts on one sheet.

Promises from stores are not inventory

A date in an email from a supplier is a hope. We still draw it, in a different band from a part that is physically in the cage. Mixing those two colours is how a sequence becomes fiction.

Jobs that share a crane

The failure history may say three housings want attention. The yard may have one crane and one rigger. Parallelism on a slide is not parallelism in the rain. We ask who holds the permit before we stack bars.

Deferral is a name, not a shame

Work that misses the window should be named on the same sheet, with the reason (lead time, access, hours). A separate “later list” in someone’s notebook is how it returns as an unplanned stop.

If your stores list and your outage date already disagree, that disagreement is the start of shutdown-window planning, not a reason to wait until the gate opens.
