The
PDSA improvement cycle was created by
Walter Shewhart where Dr. Deming learned about it. An improvement process is now part of many management improvement methods (
A3 for lean manufacturing, DMAIC for
six sigma
and many other modifications). They are fairly similar in many ways.
The PDSA cycle (Plan, Do, Study, Act) has a few key pieces that are
either absent in most others processes of greatly de-emphasized which is
why I prefer it (A3 is my second favorite).
The PDSA cycle is a learning cycle based on experiments. When using the
PDSA cycle prediction of the results are important.
This is important for several reasons but most notably due to an
understanding of the theory of knowledge.
