Systems Development Foundations: Models, Methodologies & SDLCUnit 1 of Systems Analysis and Design introduces core concepts like systems development life cycle (SDLC), process models (waterfall, iterative, agile), and key methodologies (structured, object-oriented, service-oriented). It explains how to classify systems, analyze feasibility, and understand stakeholder roles—essen10 min readUnit 2 · 5 hrs
Systems Planning: Feasibility, Scope, Alternatives & Project ManagementUnit 2 of Systems Analysis and Design covers the critical planning phase where IT projects are evaluated for feasibility, scope is defined, alternative solutions are compared, and project management frameworks (like Agile and Waterfall) are selected to ensure successful system development.9 min readUnit 3 · 13 hrs
Analysis Techniques, Models & Tools in Systems DevelopmentUnit 3 of Systems Analysis and Design explores how to systematically gather, analyze, and document user requirements, process flows, and system constraints using structured techniques like DFDs, UML, and interviews—critical for designing IT solutions that meet real-world needs.14 min readUnit 4 · 7 hrs
Design Principles, Techniques & ToolsUnit 4 of Systems Analysis and Design covers system design fundamentals, including design principles (modularity, coupling, cohesion), design techniques (DFD, ERD, UML), user interface design, and prototyping tools, with real-world applications in Nepalese software and business systems.5 min readUnit 5 · 4 hrs
Implementation & Maintenance: Coding, Testing, Deployment & UpkeepUnit 5 of Systems Analysis and Design covers the final stages of SDLC—coding, testing, deployment, and post-implementation maintenance—with real-world examples from Nepalese apps (eSewa, Daraz) and global tech (Google, WhatsApp), plus exam-focused comparisons of testing types and maintenance strategies.9 min read
