Value stream mapping on the wastewater SCADA modernization ART shows coding, build, and unit test, but skips the multi-week safety-approval and change-advisory queues that dominate calendar time. What is missing from the map?
Select an answer to reveal the explanation.
Short Explanation
Mapping only the wrench-turning and skipping the permit desk is how a two-day code change becomes a six-week calendar adventure. The development value stream includes those approval and compliance queues. If it eats the calendar, it belongs on the wall.
Full Explanation
Include the full development value stream on the wastewater SCADA modernization ART map, including approval and compliance queues that create wait. Maps that show only coding, build, and unit test hide the multi-week safety-approval and CAB delays that dominate calendar time. A separate incidents-only map kept apart from development flow misses release path delays. Story-point burn-ups do not replace drawing queues. An organization chart of the safety board is not a timed queue. Exam caveat: sensitive compliance details can be summarized, but duration and entry criteria of approval waits must still appear. Operational check: add safety-approval and CAB steps with measured wait, identify whether they are the constraint, and target policy or cadence experiments so plant modernization reaches production without pretending wrench time was the delay. In municipal and civic service contexts, record the rationale in the ART working agreements or improvement backlog so future PIs preserve the control, and re-validate after the next Inspect and Adapt against resident-facing outcomes rather than activity theater. Confirm owners, success measures, and a re-check date so the practice remains inspectable.
