In the 1950s, management consultant Dr William Edwards Deming developed a method ofidentifying why some products or processes don't work to achieve the quality objectives. Hisapproach of Plan-Do-Check-Act (PDCA) model has since become a popular strategy tool, usedby many different types of organizations. It allows them to formulate theories about what needsto change, and then test them in a "continuous excellence loop." Explain the PDCA concept incontinuous improvement in designing quality management programme towards continuousbusiness process improvements.
Why is it that testing can only determine whether or not mistakes have been made, but not whether or not mistakes have not been made?

Calculate the capability coefficients Cp, Cpk and state whether or not the machine is capable of producing compliant parts, i.e. whether or not the data dispersion is well centred. If applicable, calculate the adjustment coefficient Cr.b. If scrap is obtained, state whether it is recoverable or non-recoverable and calculate the percentage of scrap.c. Plot the limits of the tolerance field and the distribution of the measured data (using mean and standard deviation).
