    • Method, apparatus and product for analyzing a quality control regimen comprising one or more quality control tests, to determine if the tests are in statistical control, and therefore could be removed from the regimen or sampled at a different rate. On sample data relating to each of the tests, there is determined Cpi, a measure of the spread of the data, which is simply the ratio of the magnitude of the actual range of the data, to the magnitude of calculated statistical range of the data. There is also determined CPKi, which is a measure of how close the spread of the data is to the upper or lower limit of the data. For convenience, the magnitude of Cpi is represented as a vertical bar graph, with the value of CPKi shown as a position of the bar graph within normalized limits. Using Cpi and CPKi decisions regarding removal of each the test can be made. One or more tests are then selected for removal or to have a different sampling rate, and “What If” scenarios then performed to see how the testing regimen would have performed without the test(s) or at the different sampling rate.
    • 用于分析包括一个或多个质量控制测试的质量控制方案的方法,装置和产品,以确定测试是否处于统计学控制中,因此可以从该方案中移除或以不同的速率进行采样。 关于与每个测试有关的样本数据,确定Cpi,数据的扩展的度量,其仅仅是数据的实际范围的大小的比率与数据的计算的统计范围的大小 。 还有确定CPKi,它是数据传播距离数据上限或下限的度量。 为了方便起见,Cpi的大小表示为垂直条形图,其中CPKi的值显示为条形图在标准化范围内的位置。 可以使用Cpi和CPKi关于每个测试的移除的决定。 然后选择一个或多个测试用于去除或具有不同的采样率,然后执行“如果”(If If)“情况,以了解测试方案如何在没有测试或不同采样率的情况下进行。
