The Plan-Do-Study-Act (PDSA) cycle is a systematic method used for continuous improvement in various fields, including healthcare and business. It consists of four steps: first, you plan a change or test aimed at improvement; second, you implement the change (do); third, you study the results to see if the change was effective; and finally, you act on what you learned, either by adopting the change or refining it further. This iterative process encourages learning and adaptation, allowing teams to make informed decisions based on data. By repeating the cycle, organizations can gradually enhance their processes and outcomes, fostering a culture of ongoing improvement and innovation.
