Topics of this game:
  • The first phase of the SDLC in which an organization’s total information system needs are analyzed and arranged, and in which a potential information systems project is identified and an argument for continuing or not continuing with the project is presented.
  • The process of developing and maintaining an information system.
  • A systems development approach that originated in northern Europe, in which users and the improvement of their work lives are the central focus.
  • Software designed to process data and support users in an organization. Examples include spreadsheets, word processors, and database management systems.
  • The organizational role most responsible for the analysis and design of information systems.
  • A structured process in which users, managers, and analysts work together for several days in a series of intensive meetings to specify or review system requirements.
  • Building a scaled-down version of the desired information system.
  • A group of interrelated procedures used for a business function, with an identifiable boundary, working together for some purpose.
  • An irreducible part or aggregation of parts that make up a system, also called a subsystem.
  • Dependence of one part of the system on one or more other system parts.
  • The line that marks the inside and outside of a system and that sets off the system from its environment.
  • The overall goal or function of a system.
  • Phase of the SDLC, in which the system chosen for development in systems analysis is first described independently of any computer platform and is then transformed into technology-specific details from which all programming and system construction can be accomplished.
  • Phase of the SDLC, in which the current system is studied and alternative replacement systems are proposed.
  • Everything external to a system that interacts with the system.
  • Point of contact where a system meets its environment or where subsystems meet each other.
  • A limit to what a system can accomplish.
  • Final phase of the SDLC, in which the information system is coded, tested, and installed in the organization, and in which the information system is systematically repaired and improved.
  • A standard process followed in an organization to conduct all the steps necessary to analyze, design, implement, and maintain information systems.
  • The series of steps used to mark the phases of development for an information system
  • The process of breaking the description of a system down into small components; also known as functional decomposition.
  • Dividing a system up into chunks or modules of a relatively uniform size.
  • The extent to which subsystems depend on each other.
  • The extent to which a system or subsystem performs a single function.
  • Software tools that provide automated support for some portion of the systems development process.
  • A centralized database that contains all diagrams, forms and report definitions, data structures, data definitions, process flows and logic, and definitions of other organizational and system components; it provides a set of mechanisms and structures to achieve seamless data-to-tool and data-to-data integration.
  • Systems development methodology created to radically decrease the time needed to design and implement information systems.
  • Current approaches to systems development that focus on adaptive methodologies, people instead of roles, and an overall self-adaptive development process.
