Standardized work

The posted sequence is load 5, rough cut 16, finish cut 11, deburr 6, in-cell check 4, and mark the rev 4. The rule is: do not run if the traveler rev differs from Rev C. The 12-minute walk for a blank rev is not on the sheet. The sheet says what was expected. It does not say what cell 2 did today.

What it makes visible

The posted sequence, the Rev C rule, and the walk that is not on the sheet.

When it is useful

When the observed day does not match the posted method.

Who uses it

Devon Cho runs it. Mara Ellison holds the release rule in front of it.

What it takes

The six elements and times, drawing Rev C, and the rule not to run a mismatched traveler.

What it leaves

A posted method of 46 minutes, a stop rule when the traveler is not Rev C, and a 12-minute walk the sheet does not list.

The underlying record

The six elements posted for Devon Cho, the rule that the traveler match Rev C, and the walk that sheet does not contain are what the balance chart, the control plan, and the cell walks are about.

What this sheet still leaves out

It has no evidence of what happened today.
