What activity is performed in the 'Study' phase of the Deming Cycle?

In the 'Study' phase of the Deming Cycle, the key activity is to analyze the results of the tests or changes that were implemented and compare these outcomes to the predefined goals or objectives. This phase focuses on assessing performance data to determine whether the changes made led to the desired improvements.

It is crucial to understand that this phase is not about development of new strategies or direct implementation of changes but rather reflects on how effective the initiatives were in achieving the intended results. By examining the data, teams can identify what worked, what didn’t, and why, which provides a basis for making informed decisions about future actions. This analytical approach helps to foster continuous improvement, a core principle of the Deming Cycle.

The other options involve activities that fall outside the scope of the 'Study' phase, as they either focus on developing new strategies or directly implementing procedures without the necessary evaluation of prior outcomes.
