What does the "check" step of the plan-do-check-act (PDCA) cycle require the team to do?

The "check" step of the plan-do-check-act (PDCA) cycle involves observing and evaluating the effects of the changes that have been implemented in the "do" stage. During this phase, teams collect and analyze data to understand how the changes have impacted the process or outcome. The objective is to assess whether the modifications are yielding the expected results and to identify any unforeseen consequences or areas for improvement.

By focusing on observation and evaluation, teams can make informed decisions based on actual performance data rather than assumptions. This step is crucial for validating the effectiveness of the changes and ensuring that subsequent actions taken in the "act" phase are based on solid evidence. It emphasizes a systematic approach to learning and continuous improvement within an organization.
