Which System Development Life Cycle phase focuses on enhancements and fixes after initial deployment?

The Maintenance Phase is crucial in the System Development Life Cycle (SDLC) because it addresses the ongoing support and improvements required after the system has been deployed. Once the initial version of the software is in operation, this phase involves a variety of tasks such as fixing bugs, applying updates, and adding new features based on user feedback and changing requirements.

During the Maintenance Phase, the software undergoes modifications to enhance its performance, ensure compatibility with new hardware or software, and maintain overall efficiency. This phase ensures that the system continues to meet user needs and adapts to any changes in the business environment. By focusing on enhancements and fixes, this phase plays a vital role in the long-term success and usability of the software system.

In contrast, the other phases serve specific functions that occur earlier in the SDLC. For example, the Planning Phase is focused on assessing requirements and deciding on the project’s direction. The Deployment Phase involves the actual rollout of the software to users, while the Testing Phase is centered on validating that the system functions as intended before its release. The Maintenance Phase is where the ongoing care and improvement of the software take place, making it unique in its focus on post-deployment enhancements and fixes.
