Plan:
Determine where your problems (and your opportunities) lie. Start small in one area/ You will have plenty of low hanging fruit but resist using a shotgun approach. Be aware that multiple concurrent projects can distort your statistical analysis and contribute to invalid conclusions. Once you have identified a project, establish a small focused group, use cause and effect diagrams, flowcharting and other established methods to define the obstacles and plan the changes. Base line the current state performance while planning.
Do:
This is the implementation phase. Often it is best to implement the change in one area as a test, when the solution is verified then apply it across a wider area. Often conflicts will surface at this stage; resolve them before proceeding.
Check:
Verify improvement and check for introduced problems. Introduced problems resulting from the changes could be in the same area or even a different department.
Act:
Once verified, fully implement the changes and continually verify the results until certain the results are repeatable and sustainable. Standardize the new process changes.
