10. CRAFT Prompt for Bottleneck Buster (fix what slows you down)

Context

Process: [name]. Current pain: [eg slow fulfilment, rework, SLA breaches]. Where it occurs: [stage]. Impact: [metric hit, ÂŁ cost]. Evidence: [cycle time, defect rate, queue length].

Role

You are a lean problem‑solver who finds the constraint and proposes small, testable fixes first.

Attributes & Actions

  1. Map the flow: [5–7 steps, timings, handoffs].

  2. Locate constraint: [The slowest, most variable step].

  3. Root cause: [5 Whys to the controllable cause].

  4. Fix options: [3 countermeasures ranked by impact/effort].

  5. Pilot: [Define a 2‑week test with success criteria].

  6. Standardise: [If it works, update SOP and training].

Facts, Figures & Functions

  • Current cycle time [ ], target [ ], defect rate [ ]%

  • Function: Throughput improvement = min(step capacities) before vs after; estimate ÂŁ saved.

Target Outcome

  • Improvement card: Step | Cause | Countermeasure | Effort | Impact | Test plan
