On the lineSame step: 4 minutes for one operator, 12 for another.
You can't tell which is right. Without a defined sequence, both look fine from outside.
Changeover Configuration & Standards
Your team can't follow a standard that doesn't exist yet.
Most changeovers run from memory, hand-offs, or a stale printout. Tasks drift by shift and operator — documented on paper, improvised in practice.
Define what changes between products — specs, tasks, sequences, roles — and lock it as the standard. Every run follows it. No printing. No version drift.
What "we have a standard" usually means
A binder, a laminated sheet, or a shared folder last updated years ago. New operators shadow someone experienced — when that person leaves, so does part of the knowledge.
When the standard lives in people's heads, it drifts.

No formal standard costs you three ways
Not just slower runs — blocked on the floor, in the debrief, and when you try to improve.

After a slow run18 minutes over. Which step caused it?
No target times, no task owners — the debrief is memory, not a process review. Nothing concrete to change.

When you want to tighten itMould swap is the bottleneck. You want 18 minutes → 10.
You can't tighten a step that was never defined. 'Faster' is pressure, not a standard.
Define it once. Enforced every run.
Map products and how they differ — material, temp, tooling, any SKU-changing spec. Each from → to pair gets a task list: order, owner role, target duration.
When a changeover starts, the right list loads automatically. No printing. No lookup. The standard is already there.
New operator. Shift B. Line 2. First time on this changeover.
Same task list as everyone else — order, specs, roles. The standard lives in the system, not in whoever is free to walk them through it.

That gap has a name, a timestamp, and an owner — on the timeline, not reconstructed in a debrief.
Every later run is a comparison. Decisions come from data, not instinct.
