PDCA was created by W Edwards Deming in the 1950’s as an easy to follow Problem Solving Cycle.

Deming was tasked with helping Japan rebuild its economy in the 1950’s.

His purpose was to use PDCA with a Continuous Improvement process to help rebuild Japanese industries so that they could compete in the world market in the future.

Brainstorm potential causes of problem using simple Brainstorming or a Cause & Effect Diagram.

Identify & agree potential Root Causes prioritising using Paired Comparisons or by Consensus Rankings and asking the 5 WHY’s

Set up methods to capture ‘REAL’ data.

Implement ‘QUICK FIXES’ to protect the customer

Make Process Flow Diagram

Analyse ‘REAL DATA’ & show graphically.

Benchmarking - Compare Best Practices

Brainstorm where else may they have this problem, find out what they do to resolve it.
