System Proposal
System Development Life Cycle (SDLC)
Topics • List and describe the classic functions of managers: planning, organizing, directing, and controlling • Define “system,” “analysis,” and “design” • Describe the principal functions of the systems analyst • List and describe the phases of the systems development life cycle (SDLC) • Describe various data-gathering and analysis tools • List and describe various system testing methods • List and describe various system conversion methods
Classic Management Functions • Planning – devising plans for the organization and setting goals to achieve the plan • Organizing – deciding how to use the organization’s resources and includes hiring and training workers • Directing – guiding employees to perform their work in a way that supports the organization’s goals • Controlling – monitoring the organization’s progress toward reaching its goals
Levels of Management • Strategic level • Long range • Primary function: planning • Tactical level • Primary functions – organizing and staffing • Operational level • Primary functions – directing and controlling
System Development Life Cycle (SDLC) • Managers at each level need information to help them make decisions, so they rely on some type of Information System. • How are Information Systems purchased or built? • The process which includes analyzing the system requirements to designing and implementing a new system is called the System Development Life Cycle (SDLC).
Systems Analysis Design • System – an organized set of related components established to accomplish a certain task • Computer system – a system that has a computer as one of its components
• Analysis - Studying an existing system to determine how it works and how it meets users’ needs • Typically happens as a result of some impetus for change,
