The purpose of this article is to explain what “control charts” are, The repetitive nature of several accounting processes and procedures lend themselves very well to this type of statistical analysis. What are Here are a couple of examples.

Analysis of the Control Chart Once a control chart is made, it is even more important to understand how to interpret them and realize when there is a problem. All processes have some kind of variation and this process variation can be partitioned into two main components. First there is natural process variation, frequently called How to Create a Control Chart. Control charts are an efficient way of analyzing performance data to evaluate a process. Control charts have many uses; they can be used in manufacturing to test if machinery are producing products within Of course, points beyond the control limits always apply.
