Plan-Do-Check-Act Cycle of Decision-Making
There are a number of tools and techniques used to make sound business decisions that will help to resolve a particular problem or area that needs improvement. There is not one correct tool or technique to be used for each problem faced and not all are appropriate for all problems. He or she should examine the available tools and techniques and apply one or more than one that will help to resolve the problem faced. One of those tools and techniques is the "Plan-Do-Check-Act" or PDCA cycle. The PDCA cycle is made up of four stages, Plan, Do, Check, and Act that are progressed in order and are dependent on each stages success.

In the case of solving a performance issue with a particular application in a Citrix environment, the plan was to apply a patch that the manufacturer had provided to resolve the performance issue. The patch was applied and did in fact; resolve the performance issue of the application in a Terminal server environment.
Since the third stage was deemed successful, the Check stage, the last stage would apply the plan to the remaining Citrix servers. This would involve applying the vendors supplied patch file to all other Citrix servers running the application identified in the Plan stage. Once the patch is applied to the other Citrix servers, the cycle is complete and the problem can be considered resolved. If the third stage, the Check stage, had failed the cycle is repeated until all stages can complete. Or, if the initial plan was to apply a serious of patches, one could apply each patch, one at a time, until the issue was resolved.
Another good example of when one would use the PDCA cycle is to determine when a security patch or patches issued by a manufacturer broke another vendor 's application. The plan would involve uninstalling each patch, one-at-a-time, to determine which patch caused the other application to break. Once the patch was identified on one system the patch on the other systems could be removed, during the Act stage, to resolve the performance issue.
