Define the signal that starts the workflow
Lean routines fail when observations become loose notes. Start by naming the source routine and the minimum context needed to route follow-up.
- Source routine such as 5S, Gemba, Kaizen, LPA, Andon, TPM, A3, or 8D.
- Area, process, line, workstation, equipment, product, or shift context.
- Observation, failed item, abnormal condition, improvement idea, or issue description.
- Evidence, severity, immediate containment, and required response time.
