Which phase is focused on sustaining and enhancing an application?

• A. Initiate Phase
• B. Build Phase
• C. Release Phase
• D. Optimize Phase

Answer: (D)

Maintaining and improving an application after it’s released is all about continuous optimization and long-term care. After deployment, the focus shifts to monitoring usage, gathering feedback, fixing issues, boosting performance, applying updates, and adding enhancements to keep delivering value over time. This ongoing effort—addressing incidents, tuning for efficiency, and evolving features to meet changing needs—defines the phase dedicated to sustaining and enhancing the app. The other phases lay the groundwork: Initiate sets goals and scope, Build creates the functionality, and Release makes the app available. But sustaining and enhancing through ongoing improvements is what the optimization phase is all about.
