Catapult Exercise COPQ/CODND: Create histograms for the two sets of data created from shooting the catapult. Determine the center of the process and then establish upper and lower specification limits from the center using a distance specified by the instructor (e.g., 3 in. from mean projection distance). A part can be reworked if it is outside the specification but close to the limit (e.g., 1 in.), as specified by instructor. Compute the COPQ/CODND for each set of data given the following unit costs: inspection costs of $10, defect costs of $20, rework costs of $100, and scrap costs of $200. Estimate annual savings from process change, considering 10,000 catapult projections are made annually.
