SDLC Models | Kerala PSC | Computer Programmer | Database Administrator | System Analyst

🎯 Software Engineering | 03 SDLC Models Explained | Kerala PSC Exams (Computer Programmer, DBA, System Analyst, System Manager) In this video, we dive into Software Development Life Cycle (SDLC) Models—a fundamental concept in software engineering. SDLC provides a structured roadmap for developing high-quality software, from planning and requirement analysis to testing, deployment, and maintenance. ✅ Why SDLC Models Matter We explain why life cycle models are essential for: • Ensuring process clarity and control • Managing risks and meeting deadlines • Facilitating team coordination and stakeholder communication • Tracking progress and maintaining quality 🔍 SDLC Models Covered: Waterfall Model – A linear and phase-dependent approach best suited for well-defined projects. V-Model – Emphasizes verification and validation alongside development. Incremental Model – Delivers software in parts, ideal for evolving requirements. Iterative Model – Focuses on refining software through repeated cycles. Spiral Model – Combines iterative development with robust risk analysis. Agile Model – Prioritizes flexibility, collaboration, and customer feedback. Scrum Model – A framework within Agile for rapid and collaborative delivery. Prototype Model – Helps refine vague requirements through mock-up systems. RAD Model (Rapid Application Development) – Speeds up development using prototypes and user involvement. Big Bang Model – An informal approach best for small or experimental projects. 📊 We also compare these models on: • Flexibility • Risk Management • User Involvement • Testing Strategy • Time-to-Market • Project Suitability 📚 Ideal for Kerala PSC Aspirants preparing for roles like: Computer Programmer Database Administrator System Analyst Computer Programmer-cum-Operator System Manager By the end of this session, you’ll clearly understand which SDLC model fits what type of project—and how they are likely to be asked in Kerala PSC technical exams.
