💡 Why This Tool Matters
Most improvement fails because teams skip straight from idea to full implementation. PDCA forces a discipline: predict what will happen, test small, measure objectively, then decide. The magic is in the Check phase — did reality match your prediction? If not, you learned something. That learning is more valuable than the fix itself.
⚡ Facilitator Pro Tip
The most common PDCA mistake: skipping Check. Teams implement, declare victory, and move on. Without objective before/after data, you don't know if the change worked — you just think it did. Force the comparison: what was the metric before? What is it now?
H Header
P
PLAN — What will you try?
Hypothesize before you act. What do you expect to happen?
D
DO — Run the experiment
Test small first. One shift, one area, one line. Document everything.
C
CHECK — What happened?
Data, not feelings. Compare before vs. after. Did reality match your prediction?
A
ACT — What's next?
Three choices: standardize, adjust, or abandon. Then start the next cycle.
