Another example from production is the process of analysis of line occurring on the shop floor. This process should include systematic periodical analysis of rejections by reason, and present the results in a suitable information report that pinpoints the major reasons, and trends in these reasons, for management to take corrective actions to control rejections and keep them within acceptable limits. Such a process of analysis and summarisation of line rejection events is clearly superior to a process which merely inquires into each individual rejection as it occurs.
