    Study Notes

    Chapter 2: System Development Life Cycle Models

    • System Analysis and Design Fundamentals (CSC 1403) is the course related to this chapter
    • Learning objectives for this topic include
      • Identifying traditional SDLC models
      • Explaining differences between system life cycle models in system development
      • Listing all SDLC stages

    2.1 Traditional Life Cycle Models

    • Traditional Life Cycle Models are structured approaches used in software development and system engineering
    • They are methodical, orderly, and linear, often with clearly defined stages.

    2.1.1 Examples of Traditional Life Cycle Models

    • Waterfall Model: A linear approach; each phase (Requirements, Design, Implementation, Testing, Deployment, and Maintenance) must be completed before moving to the next
    • V-Model: Extends the Waterfall model, emphasizing testing and verification at each development stage. The verification and validation phases occur in reverse order of the development phases

    2.1.2 Further Models

    • Incremental Model: Divides a project into smaller segments, developing and delivering portions incrementally.
    • Iterative Model: Focuses on refining and revisiting processes through repeated cycles to improve the system
    • Prototype Model: Involves creating an initial prototype to gather user feedback and refine requirements.

    2.1.3 Waterfall Model Diagram

    • The diagram shows a sequence of stages:
      • Requirement Analysis
      • System Design
      • Implementation
      • Testing
      • Deployment
      • Maintenance

    2.1.4 V-Model Diagram

    • The diagram is shaped like a 'V'
      • Verification Phases: correspond to the stages in reverse order of the development stages
      • Validation Phases: corresponds to the stages of the development in a more direct order
      • Top of the V –Requirement gathering
      • Bottom of the V –Coding

    2.1.5 Incremental and Iterative Model Diagrams

    • Shows a cyclical process, indicating refinement and repetition through multiple iterations
    • The diagrams emphasize repeated cycles of planning, building, and testing, contributing to improvement and refinement in the developed system.

    2.1.5 Prototype Model Diagram

    • Shows a linear path from initial requirement gathering to quick design to building and refining prototypes, and finally to user evaluations

    2.2 Modern Life Cycle Models

    • Modern Life Cycle Models aim for flexibility, adaptability, iterative progress, and accommodating dynamic business requirements, and evolving technologies.
    • They focus on:
      • Continuous improvement
      • Collaboration
      • Faster delivery

    2.2.1 Examples of Modern Life Cycle Models

    • Rapid Application Development (RAD): A modern software development methodology emphasizing speed, flexibility, and iterative development.
      • Minimizes planning and maximizes user involvement
      • Effective in projects with rapidly changing requirements or in short timeframes
    • Agile Model: A flexible, iterative approach promoting collaboration and feedback for small, quick releases.
    • Scrum: A subset of Agile, focusing on short development cycles (sprints) using roles like Scrum Master and Product Owner.
    • Kanban: A lean methodology utilizing visual workflows and limiting work in progress to enhance efficiency.
    • DevOps: Combining development and operations to boost collaboration, automate processes and enable continuous delivery and integration
    • Spiral Model: Combining iterative development with risk-driven approach, repeatedly going through planning, design, building, and testing phases

    2.3 Overview SDLC Stages

    • Traditional methodology for developing, maintaining, and replacing information systems
    • Consists of five phases:
      • Planning and Selection
      • Analysis
      • Design
      • Implementation
      • Maintenance

    2.3.1 Planning Phase

    • Identifying, analyzing, prioritizing, and arranging organization's overall information system needs

    2.3.2 Analysis Phase

    • Studying current procedures and information systems
      • Determining requirements
      • Generating alternative designs
      • Comparing alternatives
      • Recommending the best alternative

    2.3.3 Design Phase

    • Describing recommended solutions, converting into logical and then physical system specifications
      • Logical design details all functional system features independently of platform
      • Physical design translates logical specifications into technology details for programming and system construction

    2.3.4 Implementation Phase

    • Coding, testing, installing, and supporting the information system

    2.3.5 Maintenance Phase

    • The final phase of SDLC
    • Repairing and improving the information system to reflect evolving business conditions.
      • Making user-requested changes

    2.3.6 SDLC Products / Deliverables table

    • Detailed explanation of products, outputs, or deliverables for each phase (Planning, Analysis, Design, Implementation, Maintenance) of the SDLC.
