What does the 'test changes' step in the PDSA cycle involve?

The step of 'test changes' in the PDSA (Plan-Do-Study-Act) cycle primarily involves observing the results after planning and implementing a small-scale test of change. This phase is critical as it allows teams to determine whether the changes made during the 'Do' phase are effective and lead to the desired improvement. By closely monitoring outcomes and collecting data after the test, teams can assess whether the changes are yielding positive results and what modifications might be needed.

This observational element is essential because it provides evidence that informs subsequent actions. The insights gained during this step will shape the understanding of the initiative's impact and guide future iterations of the PDSA cycle. This step is also vital for building a theoretical understanding of the change processes within the specific context of the implementation, making it foundational for quality improvement efforts.
