Construction: Pre Control charts are constructed keeping specifications on the Y-axis and the number of events/days on X-axis, with a central zone of 2 S.D limits, a peripheral zone of 3rd S.D, and a red zone of Medical Intolerance.. We can plot daily patient lab values on the chart to observe a general variability pattern, which remains constant in the stable population served. Advantages: 1. Blessings for the service industry 2. No financial expense on commercial controls 3. Pertains to the local population 4. Any instance of increase in variability will alert us, before the control values, giving us enough time to investigate the process error and set corrective steps, before the error actually reaches the patient investigation. Disadvantages 1. Needs a statistically skilled black belt 2. Loads of work for BB 3. The convincing ability of MBB 4.No pre-existing guidelines or format Good Use: Healthcare industry, particularly hospitals l

Good evening Maynu, Lean is about limiting work process to value added activities only And Six Sigma looks at minimising variability. Combining both ensures best possible results from a work process, from both the customer end and production end. Regards, Arvind Khanijo
