AZ400-Q: expose blocked work
Work items spend weeks waiting for security review. Which board design best reveals the bottleneck?
- A) Add an explicit security-review state and measure time spent there. ✓
- B) Delete blocked items from the board.
- C) Increase the number of labels without a workflow.
- D) Measure only how many items were created. Answer: A. A visible state and elapsed-time measure identify where flow is constrained. Why not the others: Hiding, relabelling, or counting arrivals does not measure the wait.
