2. Analysis: This phase involves analyzing the requirements gathered in the planning phase to create a detailed system design specification.
3. Design: During this phase, the system architecture and database design are created based on the specifications outlined in the analysis phase.
4. Implementation: In this phase, actual coding and programming take place to build the software product according to the design specifications.
5. Testing: The software product is thoroughly tested for bugs, errors, and performance issues to ensure that it meets quality standards.
6. Deployment: Once testing is complete, the software product is deployed to production environments for end-users to access and utilize.
7. Maintenance: After deployment, ongoing maintenance and support activities are carried out to address any issues that arise and make necessary updates or enhancements.

The SDLC provides a systematic approach to software development that helps ensure projects are completed on time, within budget, and with high quality. By following a structured process like SDLC, software engineers can effectively manage risks, improve collaboration among team members, and deliver successful software solutions that meet client expectations.

In conclusion, understanding and implementing the Software Development Life Cycle (SDLC) is crucial for achieving success in software engineering projects. By following this structured framework from start to finish, software engineers can streamline their development processes, increase efficiency, and deliver high-quality software products that meet user needs and business requirements.
