However, multivariate control charts are more difficult to interpret than classic Shewhart control charts. For example, the scale on multivariate control charts is unrelated to the scale of any of the variables. Also, out-of-control signals on multivariate control charts do not reveal which variable (or combination of variables) caused the signal. Also called: Shewhart chart, statistical process control chart. The control chart is a graph used to study how a process changes over time. Data are plotted in time order. A control chart always has a central line for the average, an upper line for the upper control limit, and a lower line for the lower control limit. Selecting the right control chart is often a challenge. The procedure below shows how to select the right chart for the right situation. The control charts included are four attributes control charts (p, np, c, and u) and three variables control charts (Xbar-R, Xbar-s, and X- mR). This chart shows the changes in the process over time. By getting an insight into the process changes, it is possible to spot problems and correct them. Project managers frequently use this chart in quality control processes. It also gives a way to control ongoing processes by searching for problems and correcting them.

### Attribute control charts are often used to analyze these types of data in the There are two ways to track this counting type data, depending on what you are
