01
Step Register
One row per step with the touch time inside it and the wait before it in separate columns, plus a running elapsed figure so a reader can see which single gap moved the total. Zero and blank mean different things: one is a step that runs straight into the next, the other is a wait nobody has timed.
02
Rework Loop Register
Every loop with its measured rate, the record it was counted in with the raw counts written out, the mechanism causing it, and the days it adds per occurrence. Ranking by days added rather than by rate reorders the list, which is the point of carrying both.
03
The caused-by column
Loops cause loops. A late loop is usually the visible end of a missing field four steps upstream, and the two sit in different lanes, so the register carries the chain. Fixing the last loop in a chain buys nothing, because the next job arrives with the same gap.
04
Handoff Matrix
One row per lane crossing with the queue time, the arrival quality answered only by the receiving lane, the rejection rate, and what the receiver has to chase every single time. That last cell is almost always one or two specific missing fields, and a missing field is fixable.
05
System Touchpoints
Where the same information gets entered by hand into a second, third and fifth system. Re-keying is never a step, so it never appears on any map, and it is where two records of one order quietly start to disagree.
06
The drawn map
Drawn from the Step Register rather than beside it, so the picture and the numbers cannot drift. Waits appear at their real size instead of as identical arrows, and every return path carries the share of work that takes it.
07
Mapping Standard and What a Swimlane Cannot Show
The rules on one page, plus the reference explaining why the standard picture omits both time and rework. Some notations rule sequence out on purpose: the federal function modeling standard states that its arrows do not represent flow or sequence at all.
08
Process Narrative and Handoff Notes
A filled narrative for a fictional printer with the map, the totals and the sample size, and the crossing conversations written up in the receivers' own words. Once the map holds, assigning responsibility for each step is the next piece of work.
