1. System Development Life Cycle

2. INTRODUCTION TO SDLC The Systems Development Life Cycle (SDLC) is a structured process used in software development. It consists of various phases to create a high-quality system that meets customer expectations. The SDLC is a detailed and organized process that guides developers in creating software solutions that meet both technical requirements and user expectations. Through its various phases—Planning, Feasibility Study, System Design, Development, Testing, Implementation, and Maintenance—the SDLC ensures that every aspect of the software project is addressed systematically.

3. 1. Planning Phase The planning phase involves setting the project goals, determining project scope, and developing a project plan. This phase sets the direction for the entire project.

4. 2. Feasibility Study In this phase, a feasibility study is conducted to evaluate whether the project is viable. Technical, operational, and economic aspects are considered.

5. 3. Systems Design During the design phase, the system architecture is created. This involves developing both high-level and detailed designs for the software.

6. 4. Development Phase The development phase is where the actual coding takes place. Developers write the code as per the design specifications using the selected programming languages.

7. 5. Integration & Testing In this phase, the system is integrated and tested. It ensures that the system works as expected and any bugs are identified and fixed.

8. 6. Implementation Phase The system is installed, configured, and deployed during the implementation phase. Users are trained on how to operate the system.

9. 7. Maintenance & Support Once the system is live, ongoing maintenance is required. This involves fixing issues, making updates, and providing support to users.

10. 8. Evaluation The evaluation phase ensures the system is operating as expected. Performance is measured against original goals, and feedback is gathered for future improvements.

11. Conclusion The SDLC provides a disciplined approach to software development, ensuring that all phases are completed systematically to deliver a successful product.
