What is the phase in the Software Development Life Cycle (SDLC) focused on bug fixing and enhancements?

The phase in the Software Development Life Cycle (SDLC) that is focused on bug fixing and enhancements is the maintenance phase. During this stage, developers address any issues that arise after the software has been deployed, ensuring that it continues to operate effectively and meets user needs. Maintenance includes activities such as correcting defects, making improvements to functionality, and updating the system to accommodate changes in user requirements or to integrate new technology. This phase is essential for the long-term success and usability of the software, as it helps to extend its lifecycle and adapt it to the evolving environment in which it operates.

In contrast, other phases like design and development are primarily focused on the initial creation and structural planning of the software, while requirements analysis deals with gathering and defining what the software needs to achieve before any coding begins.
