Steve's paper for the Department of Energy is a great example of how to do an improvement project. Although he did not use the PDCA terminology it has all of the elements of it. A few key items should be noted:
- The project had a stated purpose.
- Steve noted the importance of the analysis process beginning with data retrieval. They devised a data gathering system early in the process and used it throughout the improvement effort.
- Using an easy to understand control chart and a couple of Pareto charts, statistical analysis was used to identify where the problems might be and set a base line to measure against to show when they had been resolved.
- The project did not involve quick fixes and took patience. Note that the data was for 1994-2001. The initial improvement took place in the first 2 years as demonstrated by the control chart but they continued to collect data to make sure it stayed fixed and to identify new opportunities.
If Covers are out there trying to find out how to apply statistical principles and quality concepts, I think Steve has provided a good model.
