What best describes the role of maintenance in the SDLC?

The role of maintenance in the Software Development Life Cycle (SDLC) primarily focuses on ensuring the continued functionality of the system. Once a software product has been deployed, maintenance activities are crucial in addressing and correcting issues that arise, improving system performance, and adapting to changes in user needs or technology. This can include applying updates, fixing bugs, enhancing features, and ensuring that the system operates correctly over time.

Effective maintenance is vital for the longevity of the software, allowing organizations to maximize their investment and ensure that the system remains relevant and effective in fulfilling its intended purpose. This phase of the SDLC emphasizes the importance of ongoing support and adaptation to maintain the quality and efficiency of the software product once it is live.
