Measuring the effectiveness of the test solution and determining if it can be improved occurs in which PDCA phase?

The correct answer is the Check phase. This phase is fundamentally centered on evaluating the results obtained from the implemented test solution. In the Check phase, data and outcomes are analyzed to assess the effectiveness of the solution against the objectives set during the planning phase. It involves comparing the actual results to the expected results and determining if the changes made have led to the desired improvements in processes or outcomes.

During this phase, teams gather evidence about what worked well and what didn’t, providing clarity on whether the implemented solutions are achieving the intended goals. This evaluation lays the groundwork for making informed decisions about potential adjustments needed for future improvements, aligning with the continuous improvement ethos of the PDCA (Plan-Do-Check-Act) cycle. The importance of this phase cannot be overstated, as understanding the performance of a solution is essential for making data-driven decisions moving forward.
