What this skill does
Plan-Do-Check-Act (PDCA) Apply PDCA cycle for continuous improvement through iterative problem-solving and process optimization. Description Four-phase iterative cycle: Plan (identify and analyze), Do (implement changes), Check (measure results), Act (standardize or adjust). Enables systematic experimentation and improvement. Usage /plan-do-check-act [improvementgoal] Variables GOAL: Improvement target or problem to address (default: prompt for input) CYCLENUMBER: Which PDCA iteration (default: 1) Steps Phase 1: PLAN 1. Define the problem or improvement goal 2. Analyze current state (baseline metrics) 3. Identify root causes (use /why or /cause-and-effect) 4. Develop hypothesis: "If we change X, Y will improve" 5. Design experiment: what to change, how to measure success 6. Set success criteria (measurable targets) Phase 2: DO 1. Implement the planned change (small scale first) 2. Document what was actually done 3. Record any deviations from plan 4. Collect data throughout implementation 5. Note unexpected observations Phase 3: CHECK 1. Measure results against success criteria 2. Compare to baseline (before vs. after) 3. Analyze data: did hypothesis hold? 4. Identify what worked and what didn't 5. Document learnings and insights Phase 4: ACT 1. If successful: Standardize the change Update documentation Train team Create checklist/automation Monitor for regression 2. If unsuccessful: Learn and adjust Understand why it failed Refine hypothesis Start new PDCA cycle with adjusted plan 3. …
