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]
precision & repeatability is one and the same thing. it is the ability of the gauge to give the same reading when any identical characterstic is measured by the same optr. ,number of times on the same instrument.
in GRR study repeatability actually gives precision error.
