PDSA Method: Plan, Do, Study, Act
What is it?
The PDSA method (Plan, Do, Study, Act) is a cyclical framework for continuous improvement of processes and products. It is a structured approach to problem-solving and quality management, emphasizing iterative testing and learning from outcomes to achieve better results. The PDSA It is designed to test changes on a small scale before full implementation.

Brief Historical Overview
The PDSA cycle has its roots in the scientific method and was popularized by Dr. W. Edwards Deming in the mid-20th century. Initially introduced as the Plan-Do-Check-Act (PDCA) cycle by Walter A. Shewhart, Deming adapted and refined it into the PDSA cycle, focusing on the importance of learning and continuous improvement.
PDSA Steps and Questions
1. Plan
In the planning phase, the objective is to identify a goal or a problem, develop hypotheses about what the issues might be, and create a plan to test these hypotheses. It involves setting objectives and determining the steps needed to achieve them.
5 Questions for the Plannning Step
- What is the problem or goal we are addressing?
- What data do we need to collect?
- What resources are required?
- What are our success criteria?
- What potential obstacles might we face?
2. Do
The do phase involves implementing the plan and testing the hypotheses. It requires executing the planned activities and collecting data to monitor the progress and gather information on the outcomes.
5 Questions for the Doing Step
- What specific actions will we take?
- Who will be responsible for each action?
- What is our timeline for implementation?
- How will we collect data during this phase?
- What issues or challenges arise during implementation?
3. Studying
In the study phase, the data collected during the do phase is analyzed to determine whether the plan is working as expected. This step involves comparing the results against the objectives and success criteria set in the plan phase.
5 Questions for the Study Step
- What data have we collected?
- How do the results compare to our expectations?
- What trends or patterns do we see in the data?
- Were there any unexpected outcomes?
- What lessons have we learned from the results?
4. Act
The act phase involves deciding on the next steps based on the findings from the study phase. This could mean implementing the change on a larger scale, making adjustments, or starting a new PDSA cycle to test another hypothesis.
5 Questions for the Acting Step
- What changes need to be made based on our findings?
- Should we adopt, adapt, or abandon the plan?
- How will we implement these changes?
- What is our plan for the next cycle?
- How will we communicate the results and changes to stakeholders?

When to Use PDSA Method? Areas of Application
The PDSA method can be used in various contexts where continuous improvement and quality management are desired. Common areas of application include healthcare, manufacturing, education, and service industries. It is particularly useful for projects requiring iterative testing and refinement, problem-solving, and process optimization.
