  1. MBI 630: Systems Analysisand Design Toru Sakaguchi, Ph.D.

  2. Week 1: Introduction • Introduction to the Course • Systems Development Environment • Sample Case (for next class) • Interview key users • Discussion of requirements • Presentation (if time allows)

  3. Introduction • Information Systems Analysis and Design • Complex process whereby computer-based information systems are developed and maintained • Application Software • Result of systems analysis and design • Designed to support specific organizational functions or processes

  4. Data and Processes • Three key components of an information system • Data • Data Flows • Processing Logic • Data vs. Information • Data • Raw facts • Information • Derived from data • Organized in a manner that humans can understand.

  5. Organizational Responsibilities in Systems Development • Systems Analysts work in teams • Project Based • Includes • IS Manager • Programmers • Users • Other specialists • Characteristics of Successful Teams • Diversity of backgrounds • Tolerance of diversity • Clear and complete communication • Trust • Mutual Respect • Reward structure that promotes shared responsibility

  6. Skills of a Successful Systems Analyst • Analytical • Understanding of organizations • Problem solving skills • System thinking • Ability to see organizations and information systems as systems • Technical • Understanding of potential and limitations of technology • Management • Ability to manage projects, resources, risk and change • Interpersonal • Effective written and oral communication skills

  7. Systems Development Life Cycle • Series of steps used to manage the phases of development for an information system • Consists of five phases: • Planning • Analysis • Design • Implementation • Maintenance

  8. Approaches to Development • Joint Application Design (JAD) • Users, Managers and Analysts work together for several days • System requirements are reviewed • Structured meetings • Prototyping • Building a scaled-down working version of the system • Rapid Application Development (RAD) • Utilizes prototyping to delay producing system design until after user requirements are clear
