This editable Main Article is under development and subject to a disclaimer.

Process control charts are used in statistical process control for quality measurement such as in health care quality assurance.[1][2] A process is a "transformation of a set of inputs, which can include materials, actions, methods and operations into desired outputs in the form of products, information, services or - generally - results."[3]

Statistical analysis of the charts is not required.[4]

Examples are assessing methods to obtain blood cultures[5], the impact of screening for methicillin resistant Staphylococcus aureus[6] and comparing mortality in surgical units[7].
