Quality Management Tools & Techniques - Assignment Example Three design specifications are to be maintained in development of the process. The first two design specifications are measurement of distance between two parts of the process while the third specification is power in form of current. Measurement of the distance is in millimeters, where the first one, A, must be 11.5 +/- 1.0mm while the second one, B, must be 8.5 +/- 2.0mm. Finally, current, C must not exceed a maximum threshold of 2.5 amps. In order to appraise the processes technical capabilities, a histogram for the three variables will be plotted and resultant patterns used in selecting optimal set of conditions. Process testing is an essential step in development of manufacturing processes. Engineers and process owners cannot commission manufacturing processes before validating their level of compatibility with pre-determined standards. In this regard, one reason for carrying out process testing involves the need to detect errors. New processes may have technical errors which may lead to increased cost of operation. For example, the process in subject may need current exceeding the technical limit of 2.5 amps. However, optimal operation of the hard drive production process needs a maximum current of 2.5 amps, above that threshold compromise on the power efficiency of the entire production setup. In this case, testing facilitate early detection of errors which would hinder optimal performance later. Apart from errors, testing is also necessary as a means of appraising safety standards. Douglas (2008) mentioned that employees involved in operating the disk drive machine must be certain of the ir safety aspects. Conventionally, every industrial process must conform to some specified safety standards. Therefore, testing will facilitate quantification of the process’ integrity. Detection of any deviation from conformance limits warrants use of appropriate corrective measures. Normally, most processes fail to undergo thorough testing because of
