SDLC and different models of SDLC - MCQs 1. True or false. Both are used for the measure of a potential capability of a process in short term. If, however, a system is stable, capability analysis shows not only the ability of the system in the past, but also, if the system remains stable, predicts the future performance of the system. Here we will discuss on Calculation of Cp and Cpk with Example. Companies that adopt just-in-time purchasing systems often experience . As you know that Process Capability (Cp) is a statistical measurement of a process’s ability to produce parts within specified limits on a consistent basis and it gives us the idea about the width of the Bell curve. d) Sample mean b) s = R/2d2 Process Capability Analysis for Normal Distributions CP and PPM interpretation Process Spread LSL USL TARGET Specifications Case 4: CP < 1 A not capable process This process will also produce more than 2700 non-conforming PPM.
