The NHS Institute for Innovation and Improvement developed this guide as a reminder to commissioners how to create and analyse time-series data as part of their improvement work. It provides guidance to ask the right questions and to better assess whether a change has led to an improvement.


This guide is intended to support teams using run and control charts in service improvement projects. It contains sections on: the importance of time based measurements; run charts; control charts; and process changes.
