Statistical Process Control (SPC)

Statistical process control (SPC) is a method for achieving quality control in processes. It is a set of methods using statistical tools such as mean, variance and others, to detect whether the process observed is under control.

BSI publishes a number of standards outlining the cusum (or cumulative sum) method and standard attribute charting for the monitoring, control and improvement of business processes.

These standards are written with non-experts in mind and aim to make clear how the cusum method and attribute charting can be used widely throughout business, industry, commerce and the public sector.
