Study Notes

Systems Analysis Principles

  • Effective systems development involves a team effort, including stakeholders, users, managers, systems developers, and support personnel. It begins with careful planning.
  • Tools like prototyping, rapid application development (RAD), CASE tools, and object-oriented development are frequently used in systems development.
  • Systems development starts with investigating and analyzing existing systems.

Learning Objectives

  • Identify key participants in systems development and their roles.
  • Define information systems and planning, listing reasons for initiating systems projects.
  • Describe trends in enterprise resource planning (ERP) software impacting development.
  • Discuss traditional, prototyping, RAD, and end-user systems development lifecycles (advantages and disadvantages).
  • Identify factors influencing project success or failure.
  • Explain the role of CASE tools and object-oriented approaches.
  • Detail the purpose of systems investigation.
  • Discuss performance and cost objectives in systems analysis.
  • Explain the purpose of systems analysis and related tools/techniques.
