Frequently asked questions
What is PDCA?
A continuous-improvement cycle (Plan, Do, Check, Act) popularised by W. Edwards Deming, used in lean, kaizen and quality management.
How is PDCA different from PDSA?
PDSA (Plan-Do-Study-Act) is a closely related variant. The 'Study' step emphasises learning over checking conformance to target.
How long should a single PDCA cycle take?
Match the cycle to the risk and feedback loop of what you're changing. A small UI tweak: a sprint (1-2 weeks). A manufacturing process change: a month. An org-wide policy change: a quarter. The right rhythm is the shortest cycle that produces meaningful Check data — too fast and you measure noise.
