Measuring for improvement requires selecting and tracking a family of measures, consisting of outcome, process, and balancing measures. Lesson 2: how to use data for improvement. The purpose of measuring for improvement is to: keep track of what you"re learning during plan-do-study-act (pdsa) testing, answer the second question in the model for improvement, how will we know that a change is an improvement? . Because improvement happens over time, static displays of data are not helpful; you need a dynamic way to display the data, such as a run chart. A run chart is a graph that helps teams effectively interpret and communicate variation in data by showing change over time. Classifying and separating data according to specific variables, a practice called stratification, is another helpful way to understand the story the data is telling.
