What phase in DMAIC is focused on implementing and verifying changes?

The phase in DMAIC that focuses on implementing and verifying changes is the Improve phase. This phase is critical because it is where the team takes the solutions that have been developed and tested, and puts them into action to address the problems identified in the previous phases.

During the Improve phase, the team explores different solutions and selects the most effective one(s) based on their analysis. This phase involves pilot testing the solutions, measuring their effectiveness, and making adjustments as necessary to ensure that the solutions can be integrated into the existing processes. The goal is to implement changes that lead to real and sustainable improvements in the process or outcome.

Furthermore, the Improve phase emphasizes validating that the changes made lead to the desired improvements. This involves not just implementing the changes but also monitoring the results to ensure that they perform as expected and checking that the issues initially identified have been adequately addressed. This validation aspect is crucial for sustaining the success of the initiative long-term.
