SDLC Presentation in briefly and understanding
- 1. Understanding the SDLC (Software Development Life Cycle) An Overview of Key Models and Their Importance
- 2. Introduction to SDLC • The Software Development Life Cycle (SDLC) is a systematic process for building software that ensures the quality and correctness of the software built. It includes a detailed plan describing how to develop, maintain, replace and alter or enhance specific software. The SDLC process aims to produce high-quality software that meets or exceeds customer expectations, reaches completion within times and cost estimates.
- 3. Waterfall Model • The Waterfall Model is a linear sequential flow. In this model, the outcome of one phase acts as the input for the next phase. Phases: Requirements, Design, Implementation, Verification, Maintenance. • Advantages: Simple and easy to understand and use. • Disadvantages: Not suitable for complex projects or projects with changing requirements.
- 4. Spiral Model • The Spiral Model combines the idea of iterative development with the systematic aspects of the Waterfall Model. This model focuses on risk assessment and mitigation. Phases: Planning, Risk Analysis, Engineering, Evaluation. • Advantages: Good for large, complex, and high-risk projects. • Disadvantages: Can be costly and time- consuming.
- 5. RAD (Rapid Application Development) Model • The RAD Model emphasizes quick development and iteration. It uses component-based construction. • Phases: Requirements Planning, User Design, Construction, Cutover. • Advantages: Fast delivery of products. • Disadvantages: Not suitable for smaller projects.
- 6. Iterative Model • The Iterative Model involves development and refinement through repeated cycles. Each iteration includes planning, design, coding, and testing. • Advantages: Issues are discovered and addressed during iterations. • Disadvantages: Requires more resources.
- 7. Agile Model • The Agile Model is an incremental and iterative approach. It focuses on customer satisfaction through continuous delivery of functional software. • Phases: Planning, Design, Development, Testing, Review. • Advantages: Flexible and customer-focused. • Disadvantages: Can be difficult to predict, lacks documentation.
- 8. Conclusion • SDLC models provide a structured approach to software development. Choosing the right model depends on project requirements, complexity, and risk. Understanding different SDLC models helps in selecting the best approach for a successful project.
