The Enhance Phase is the final stage of the Plan-Do-Study-Act, a total quality management excellence improvement framework that guides professionals in recognizing areas for improvement and acting upon them systematically. This phase makes up a crucial part of any quality management or improvement initiative and follows the implementation of the recommended changes from the Do Phase.

In the Development Phase, teams of professionals will focus on developing and implementing answers to the problems that were identified during the Plan Phase. These solutions must meet specific requirements and must carry a high probability of giving the required results. These standards may include guidelines for budgets, timelines, and input information. Effective answers are proactive and directed at both the problems that are symptomatic and those that gave origin to these symptoms.

The first step in this phase is to prioritize and select solutions to tackle the problems at hand. Numerous tools can help with this, such as SWOT analysis. Once key solutions are selected, the team must assess and refine their potential effects. This entails closely examining the influence of the changes within both current operational and economic systems. Also, anticipate eventual inter-site effects and in their relations with existing rules.

Detailed plans will be made for implementing these answers into actual practice. Here too, a detailed assessment of present limitations as well as potential challenges must occur in this step to protect against unfavorable changes from occurring during the process of deployment.

Key considerations such as stakeholder obligations - how certain that stakeholders will be made aware and obtain actual involvement with the recent changes - need also to be addressed carefully. Both engagement regarding expectations placed on particular persons or components of the site environment, as well as verification of outcomes achieved, should be comprehensively integrated.

Lastly, with the assistance of information originating in the Study Phase, ongoing assessments of process changes, operational information and cost information should be checked. While they must undergo more frequent and profound oversight throughout the first few months, a deeper 'probing depth' is considered to be established soon after.
