I would rather call it right yield reported.
You must treat yield as a measure of quality. Now it can be calculated in two ways as you have demostrated.
1. count defective ( traditional approach)
2. count defects ( Six Sigma Way)
further it should be understood that counting defects is more accurate measure of gauging quality/ improvement or…[Read more]
The savings can be classified in two broad catgories
1.tangible 2. non tangible
all projects may not necessarily yield direct tangible gains nor it is a condition in project closure.You can quantify the gains in terms of Reduction in D.P.U.,Reduction in RPN number,improvement in capability index. Most appropriate in your case would be reduction…[Read more]
