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.
