What is the purpose of the "Do" stage in the PDCA cycle?

The purpose of the "Do" stage in the PDCA (Plan-Do-Check-Act) cycle is to implement the change. This stage is essential as it is where the actual execution of the plan occurs. After careful planning in the "Plan" stage, this moment focuses on the real-world application of the strategies and processes that were previously developed.

During the "Do" stage, team members carry out the tasks and activities designed to bring about improvement. It involves taking the theories and ideas that were carefully crafted and turning them into practical actions. This implementation phase also allows for observations to be made regarding the processes in action, providing valuable insights that will be crucial for the subsequent "Check" stage.

By concentrating on the execution of planned changes, the "Do" stage lays the groundwork for evaluating the effectiveness of those changes and ensures that the team can gather the necessary data for assessing outcomes. This results in a smooth transition into checking how well the changes performed against expectations.
