A Statistical Process Control (SPC) chart helps to see what is different to the norm. It charts changes over time and shows data plotted in time order.

NHS England guidance
Statistical process control (SPC) is a method of quality control which uses statistical methods to monitor and control a process.
SPC can help you understand the scale of a problem, gather information and identify possible causes when used together with other tools, such as process mapping and spaghetti diagrams. You will then be able to measure the impact of any change.
