Learning of the Day: Measurement of Results Variation

Remember that variation in results are natural & an inevitable part of life. You will find:

Common: Variation that exists because how management designed the process

Special: Abnormalities out of the process. Sporadic, non predictive and usually easy to discover:

How to control them:

• Reduce special causes -> Process Improvement

– “Cease dependence on inspection to achieve quality. Eliminate the need for inspection on a mass basis by building quality into the product in the first” Deming´s 3rdpoint

– Reduce Common causes

– “Improve constantly and forever the system of production and service, to improve quality and productivity, and thus constantly decrease costs” Deming´s 5thpoint

And avoid tampering (trating common variation as a special one) like demming explains in the Funnel Experiment:
