    1. Chapter 1: Introduction to Systems Analysis and Design

    2. Key Ideas More than ½ of all IS development projects Fail. Canceled before completion System is never used once finished Doesn't provide the expected benefits Most of the ones that don't fail: Are delivered late Are over budget Don't provide the features promised

    3. Key Ideas Many fail because analysts try to build wonderful systems without understanding the organization. The primarily goal is to create value for the organization.

    5. Key Ideas The systems analyst is a key person analyzing the business, identifying opportunities for improvement, and designing information systems to implement these ideas. It is important to understand and develop through practice the skills needed to successfully design and implement new information systems.

    6. SYSTEMS DEVELOPMENT LIFE CYCLE

    7. Systems Development Life Cycle

    8. Major Attributes of the Lifecycle The project Moves systematically through phases where each phase has a standard set of outputs Produces project deliverables Uses deliverables in implementation Results in actual information system Uses gradual refinement

    9. Project Phases Planning Why build the system? Analysis Who, what, when, where will the system be? Design How will the system work? Implementation System delivery

    10. Planning Identifying business value Lower costs / Increase profits Analyze feasibility Develop work plan Staff the project Control and direct project

    11. Planning
