ABSTRACT
After he hung up the phone, Carlo went to his notes from his discussions with Linda. He had learned from Linda that the Plan-Do-Check-Act cycle is intrinsic to lean thinking. Shorthand for the scientific method, and made a popular business concept by W. Edwards Deming, it breaks the usual mental paradigm of shuttling between planning and execution and forces us to learn as we make progress. Linda told him that some people think of the cycle as PDSA (Plan-Do-Study-Act) or even Allen Ward’s product development learning cycle LAMDA (Look-Ask-Model-Discuss-Act).
