The four steps used in the Model for Improvement developed to enhance organization performance; a cycle of developing, testing, measuring and implementing changes that result in improvement: The steps are as follows:

• PLAN - State objective (what needs to be improved) and identify metric for measuring accomplishment of the objective; make predictions, hypotheses and develop a plan to carry out cycle
• DO - Carry out the test, collect data or other info/ input needed; document problems, unexpected observations; and begin analysis of data
• STUDY - Complete analysis of data; compare data to predictions; and summarize what was learned
• ACT - Determine what changes are to be made, identify remaining and new questions and repeat the PDSA to continue exploring and implementing changes that result in progress toward stated objectives.
