    Study Notes

    Introduction to System Analysis and Design

    • Systems are designed to address problems, employing a methodical approach to problem-solving.
    • System Analysis and Design (SAD) primarily focuses on activities related to software development.

    Objectives of System Analysis and Design

    • Define what constitutes a system.
    • Describe the various phases of the System Development Life Cycle (SDLC).
    • Identify components involved in system analysis.
    • Illustrate the components of system design.

    Defining a System

    • A system is a collection of interrelated components working together to achieve objectives.
    • Major components include:
      • Input
      • Processing
      • Output
    • Control, as an additional element, provides feedback to ensure the desired outcomes.

    System Life Cycle

    • The System Life Cycle is a structured approach for system development and maintenance.
    • Key processes include:
      • Establishing a system project plan.
      • Preparing a System Proposal outlining problem definition, objectives, constraints, and expected benefits.
    • The System Analyst prepares the proposal, which must be approved by management to proceed.

    Phases of the System Development Life Cycle

    • Feasibility Study: Evaluates the system's viability based on:
      • Technical feasibility
      • Operational feasibility
      • Economic feasibility
      • Schedule feasibility
    • Detailed System Study: Involves thorough examination of existing operations, using tools like interviews, observations, and questionnaires.
    • Outputs include data flow diagrams, data dictionaries, and specifications regarding system functionality.

    System Analysis

    • Aims to collect data and improve system functionality by analyzing business processes and workflows.
    • Key questions addressed include:
      • What is done?
      • How is it done?
      • Who performs the tasks?
      • When and why are tasks performed?
      • How can the process be improved?
    • The outcome is a logical design that fulfills current user needs and scalability for future growth.

    System Design

    • Translates the logical system design into a physical system design.
    • Involves two main stages:
      • Preliminary or General Design: Specifies system features, costs, and benefits.
      • Structured or Detailed Design: In-depth preparation of components including input, output, databases, and processing specifications.

    Changeover Strategies

    • Direct Changeover: Risky complete replacement of the old system, requiring thorough testing and training.
    • Parallel Run: Both old and new systems operate concurrently, allowing for comparison but incurring higher costs.
    • Pilot Run: The new system operates with historical data; less expensive and risky, building user confidence through comparisons.

    Documentation

    • Essential for system continuity, consisting of:
      • User Documentation: Guides users on system operation and utilization.
      • System Documentation: Technical details addressing the system's backend processes and architecture.
