What main activity occurs during the Optimize Phase?

The Optimize Phase focuses on sustaining and enhancing the application, which involves several key activities aimed at improving its performance and ensuring that it continues to meet user needs effectively. During this phase, teams assess feedback from users, analyze performance metrics, and identify potential areas for improvement. The goal is to refine and optimize the application to enhance user experience and operational efficiency. This phase ensures that the application remains relevant and functional as business needs evolve.

While other options may represent relevant activities in the context of application development and implementation, they do not capture the primary focus of the Optimize Phase as accurately. Implementing new features is generally associated with earlier phases of development. Creating a plan for future sprints is part of the planning and development process, while conducting training sessions, although essential, primarily occurs before users start interacting with the application on a regular basis.
