Objective: 

This section introduces you to the various components and types of information systems. After finishing this section, you should be able to:

• Describe the components of an information system and how they fit together.
• Compare and contrast different types of information systems, including transaction processing, management information systems, and expert systems.
• Conduct online research on a career that interests you in information technology.
• Identify the traditional stages of the System Development Life Cycle (SDLC).
• Describe modern alternatives to a linear process of systems analysis and design.
• Describe the role of project management in the design and implementation of information systems.

Key Terms:

• Information System A combination of technology, people, and procedures used to organize, analyze, and store data.
• Information System Types The various forms of information systems including transaction processing, management, and expert systems.
• Systems Analysis and Design The study and design of a system, accomplished by examining its components and their interactions.
• System Development Life Cycle (SDLC) A methodology or framework that defines steps and tasks for developing and maintaining information systems.
• Waterfall Model A development model that breaks down project activities into a series of sequential or linear phases, each phase depending on the deliverables from the previous phase.
• Iterative Design A development model that involves designing, implementing, and testing smaller pieces of the overall project, then cycling back and doing more analysis and design.
• Planning Phase The SDLC phase that involves gathering information about the technology and software needs of an organization, deciding which options are most feasible, and setting timelines and deliverables for the entire project.
• Analysis Phase The SDLC phase that involves studying existing information systems that are already in place and the requirements for new information systems.
• Design Phase The SDLC phase that involves reviewing the system requirements document from the analysis phase and producing detailed specifications that cover all aspects of the system.
• Implementation Phase The SDLC phase that involves purchasing and installing new hardware and software, integrating the various system components, and testing the operation of the new system.
• Maintenance Phase The SDLC phase that involves monitoring and evaluating the new information system.
• Project Management The practice of initiating, planning, executing, controlling, and closing the work of a team to achieve specific goals and meet specific success criteria at the specified time.
• Systems Integration An activity that involves integrating various computing systems and software applications to function together as a whole.
• Agile Methodologies A project management process that divides a large or complex project into smaller, more manageable projects that can be completed as part of an incremental or iterative process.
• Needs Assessment A systematic process for determining and addressing needs, or “gaps” between current conditions, and desired conditions, or “wants”.
• Risk Management The identification, evaluation, and prioritization of risks followed by activities that minimize, monitor, and control the impact of the risk.

Topics Discussed:

• How do technology, people, and procedures work together in an information system?
• What are some principles of effective systems analysis and design?
• What role does project management play in the design and implementation of information systems
