CONTROL CHART WITH SINGLE DISPLAY

摘要

A statistical process control chart (308) includes a single display for the data (402) and for an analysis of the data, e.g., in the form of one or more graphical charts(404 and 406) . The chart can be implemented in a spreadsheet having multiple pages, including a page for entry of the data and a page implementing the single display. Space is also provided for entry of root causes and corrective action (407). The analysis performed on the data can include a Pareto analysis or a graph of an error rate in parts per million (404).
