PDCA has many names, like continuous improvement cycle, Deming Wheel, Ishikawa Circle, Shewart Cycle.
It is also known as plan, do, show, act.
Any search on process improvement, continuous imrpovement or even benchmarking will give you buckets of info on PDCA.
I could email you a 2 page PDCA overview if I knew how to get it to you.
Any suggestions Marc?
