Study Notes

IT 223: System Analysis and Design Fundamentals - Summer 2018

  • Course Overview: Modern organizations rely on computerized information systems to function and remain competitive. Analyzing information systems is crucial before implementation, as mistakes in this early stage significantly impact later development and cost. Competence in systems analysis is vital for modern IT professionals, including systems analysts, business analysts, and more. This introductory course covers information systems analysis and design concepts, skills, and managerial aspects. It includes structured methodologies and object-oriented techniques.

  • Course Description: The course covers different types of organizational systems, systems development life cycles, and prototyping. Topics include project management (planning, teams, cost estimation, risk analysis), requirement elicitation (interviewing, system modeling), functional/non-functional requirements, system specifications, object libraries, design patterns. The course explores Unified Modeling Language (UML) and its comparison with structured methods like SSADM. It also covers computer-aided software engineering, testing strategies, quality assurance, and verification/validation.

  • Objectives: The course aims to equip students with the organizational perspective of information technology adoption, implementation, and management rather than a purely technical viewpoint.

  • Learning Outcomes: Upon successful completion, students will be able to define various systems analysis and design concepts and terminologies.

  • Course Delivery: Lectures, demonstrations, and case study discussions.

  • Assessment: Continuous assessment (30%) and end-of-semester examination (70%).

  • Policies/Regulations: Students should review GTUC Student Handbook for policies and regulations, including academic integrity guidelines.

  • Course Materials: Whitten and Bentley's "System Analysis and Design Methods" (7th edition).

  • Course Schedule (Partial):

    • Introduction: Defining concepts like systems, components, system analysis/design, types of information systems, and the systems development process. A class test is scheduled.
    • Systems Analysis: Defining systems analysis, approaches to systems analysis, and introduction to CASE tools. Topics also include fact-finding techniques for requirements discovery and problem analysis, leading to assignment 1.
    • Modeling System Requirements: Discusses modeling system requirements, using use-case modeling and process models, culminating in assignment 2.
    • Data Modeling and Analysis: Covers data modeling, data flow diagrams, entity-relationship diagrams, and database design, as seen in assignment 3. There's a mid-semester exam scheduled.
    • Object-Oriented Analysis and Design: Reviews object-oriented analysis and modeling, object-oriented design, and modeling concepts.
    • Feasibility Analysis and Systems Design: Discusses system proposals, design, outputs, inputs, prototyping, and application architectures. This section has group presentation components in the syllabus.

  • Additional Key Concepts: System analysis, requirements discovery, use-case modeling, process modeling, data modeling, database design, feasibility analysis, systems design, design tools, object-oriented techniques.
