This then halts the entire manufacturing line, and signals others to come. Then then swarm the problem in group, doing root cause analysis. They learn and improve the process, that is the goal. It’s also mentioned that this cord is pulled about 1000 times per shift....
For the context about what actually happened, see Case study_ extract a service from big-ball-of-mud Per client application (3 of them) Refactor to module Refactor to library Change to use our service (with fallback and throttle) We would collaborate here for step 3, maybe even be involved in the earlier steps so we get to know the code base. Our service . . Simplest service possible + client library Continue developing our service … … System is ‘done enough to use’ in [[story-extract-a-service-from-big-ball-of-mud....

We usually don’t consider the entire value stream (Model_ from idea till thank you) And we certainly don’t visualise it! In Toyota they play with buffer size (aka Kanban’s WIP limit) to create problems. Maybe if we broaden the scope beyond todo-doing-done, we can do the same....
