Chapter 5

• Parallel operation cutover


  : Running two systems in parallel essentially doubles resource consumption.
• Payback method


  : Product life cycles and rapid advances in technology, the effective lives of information systems tend to be short.
• Phased cutover


  : Operating the new system in modules phasing in the new system in modules reduce the risk of a devastating system failure.
• Polymorphism


  : Ability of a variable, function or object to take on multiple forms. It allows multiple and different objects to respond to the same message.
• Procedural language


  : Well-structured steps and procedures within its programming context to compose a program.
• Project planning


  : Allocation of resources to individual applications within the framework of the strategic plan.
• Project proposal


  : Document provides management with a basis for deciding whether to proceed with the project.
• Project schedule


  : Document that formally presents management’s commitment to the project.
• Quality assurance group


  : Programmers, analysts, users, and internal auditors to simulate the operation of the system to uncover errors, omissions, and ambiguities in the design.
• Run manual


  : Computer operators use documentation transaction (input) files, master files, and output files used in the system.
• Schedule feasibility


  : The firm’s ability to implement the project within an acceptable time.
• Special-purpose system


  : Software vendors create accounting procedures to selected target segments of the economy.
• Stakeholders


  : Entities either inside or outside an organization that have direct or indirect interest in the
• Steering committee


  : An organizational committee consisting of senior-level management responsible for systems planning.
• Strategic systems planning


  : Budgeting resources for other strategic activities of systems resources at the macro level.
• Structure diagram


  : Design is usually documented by data flow and structure diagrams to depict the top-down decomposition of a hypothetical business process.
• System survey


  : Determination of what elements, if any, of the current system should be preserved as part of the new system.
• Systems analysis report


  : Analysis and recommendations for the new system.
• Systems analysis


  : Two-step process that involves a survey of the current system and then an analysis of the user’s needs.
• Systems development life cycle


  : Formal process consisting of two major phases: new systems development and maintenance.
• Systems evaluation and selection


  : An optimization process that seeks to identify the best system.
• Systems maintenance


  : Modifying the system to produce a new report or changing the length of a data field.
• Systems planning


  : Linking of individual system projects or applications to the strategic objectives of the firm.
• Systems professional


  : Systems analysts, systems engineers, database designers, and programmers gather facts about problems with the current system, analyze these facts, and formulate a solution to solve the problems.
• Systems selection report


  : The deliverable product of the systems selection process.
• Tangible benefits


  : Organization to reduce inventories and at the same time improve customer service by reducing stock outs.
• Technical feasibility


  : The physical basis for most of the system’s design features, this aspect bears heavily on the overall feasibility of the competing system.
• Third-generation languages (3GLs)


  : Program logic is executed by the programmer to specify the precise order in procedural language.
• Turnkey system


  : Completely finished and tested systems that are ready for implementation.
• Tutorial


  : Train the novice or the occasional user.
• User handbook


  Documentation will guide the user interactively in the use of the syste
• Vendor-supported system


  : Custom systems that organizations purchase from commercial vendors.
• Walkthrough


  : Analysis of system design to ensure the design is free from conceptual errors that could become programmed into the final system.
