Polaroid Case I. We Need Greenlight ' But for Which Reason? Quality control of film cartridges on R2 was a routine process, but the QC department found that there are some discrepancies between the defect rate of QC auditors and the Operators. Defects were being passed through the entire manufacturing process unnoticed. While pre-existing measurements at quality control showed low overall defect rates, there were complications in the process and interference from operators that affected QC numbers. Project Greenlight was initially necessary to allow for accurate measurement of processes and quality control during the process as opposed to the end of the process. Once implemented, Greenlight would serve to measure and…show more content…
From this analysis we conclude that the process involved in finger height is problematic and should be optimized before moving forward on analysis of other parts of the overall process. The regular violation of control limits may point to a significant contribution to overall quality control rejections. III. Quality Check “Type of Defects” (exhibit 4) and “Reported Defect Rates” (exhibit 5) suggests that the output quality of R2 has declined. The reported defective rate from the operators had decreased from under 1% to 0.5% and the defective rate from the central process auditors had increased from over 1% to levels averaging 10% (stated in case). The exhibits also show that although the types of defects noticed by the operator and auditor are same, but the number of times the defect observed by auditor is significantly higher. Factors contributing to decrease in quality of product are numerous. R2 does not inspect for the types of defects that consumers notice. Rather, it inspects for more technical, hidden defects. Operators do not follow the guidelines for interpreting control charts as most of the defects are sighted by Quality Control at the end of the process. Some problems that operators did not regard as important are not reported and result in rejection by quality control at the end of the process. Operators tweak the machines when products do not meet the process
