PDCA Cycle Tool (Plan-Do-Check-Act)
Improve any process with the PDCA / Deming cycle. Four phases — Plan, Do, Check, Act — each with their own task list, checkboxes for completion, an iteration counter for repeated cycles, theme picker, auto-save and export as SVG, PNG, JSON or text.
What problem? What hypothesis? What change will we test?
What actions? Who executes? On what scale?
What worked? What didn't? What did the data show?
What do we keep, change, or roll back? Next cycle?
