Answer #1

Answer: (1) Control charts

Explanation: There are two types of variations that takes place in a system. These are common cause variation and special cause variation. As the name suggests, common cause variations are those that are due to common or routine causes, where as, the presence of a special cause variation can be attributed to a specific cause that occurs out of the routine business functionality. To monitor both the common cause and special cause variation, control charts are used. A Control chart is the most commonly used and successful statistical process control tool that is used to study the changes taking place in a process over time.
