Implementing Deming, Volume 4: What To Do Instead of Managing by Objectives


The Deming Cycle (PDCA)

Deming Cycle (PDCA)A Dynamic Model for TQM, Health Maintenance, Improving Your Office, Personal Improvement, and so much more!

The PDCA (or Deming Cycle) was originally conceived by Walter Shewhart in the 1930's, and later adopted by W. Edwards Deming.
The model provides a framework for the improvement of a process or system. It can be used to guide the entire improvement project, or to develop specific projects once target improvement areas have been identified.

The Deming Cycle is designed to be used as a dynamic model.
The completion of one turn of the cycle flows into the beginning of the next. Following in the spirit of continuous quality improvement, the process can always be reanalyzed and a new test of change can begin. This continual cycle of change is represented in the "Ramp of Improvement". Using what we learn in one PDCA trial, we can begin another, more complex trial.

The Ramp of Improvement
This is a schematic representation of the use of the PDCA cycle in the improvement process. As each full PDCA cycle comes to completion, a new and slightly more complex project can be undertaken. This rolling over feature is integral to the continual improvement process.
