Plan-Do-Check-Act (PDCA)

What it does

Running iterative improvement cycles for any goal — personal habits, workflows, or recurring challenges — with measurable outcomes and structured learning.

Procedure

When this skill is activated, Chalie follows these steps:

1. Use the memory tool to recall prior PDCA cycles or background context for this improvement goal.
2. Use document to define the problem or improvement goal, describe the current baseline state, and form a hypothesis (“if we change X, Y will improve”).
3. Use document to set specific, measurable success criteria and design the experiment — what changes, how long to run it, and what data to collect.
4. Use document to record what was actually implemented and note any deviations from the original plan.
5. Use the schedule tool to create a reminder to check results at the agreed review date.
6. Use document to compare actual results against the success criteria, analyse whether the hypothesis held, and record key learnings.
7. Use memory to store the outcome: if successful, standardise the change; if unsuccessful, revise the hypothesis and plan the next cycle; if partial, standardise what worked and plan a follow-up cycle.
8. Use the document tool to save the completed PDCA cycle record, including baseline, results, and decision for the next step.
