  8. Planning for Information Systems and Technology

    Managing Information Systems and Technology Powered by DeSiaMore
  9. Planning for Information Systems and Technology The planning activity involves determining what should be done. Planning for information systems and technology involves determining what systems will be developed and what technology will be used in the future. Powered by DeSiaMore
  10. Planning for Information Systems and Technology (cont’d.) The planning horizon can involve varying amounts of time. Operational planning – a few weeks to a few months. Tactical planning – several months to a few years Strategic planning – several years to a decade or more Powered by DeSiaMore
  11. Planning for Information Systems and Technology (cont’d.) Planning involves evaluating risk. Risk is often related to three factors: Size of the system development project. Familiarity of the business with information technology used in the new system. Amount of structure in the systems development process. Powered by DeSiaMore
  12. Planning for Information Systems and Technology (cont’d.) Planning what information systems should be developed and what technology should be used involves selecting an application portfolio. An application portfolio is a description of what systems will be developed, and when, as well as an assessment of the risk associated with each system. Powered by DeSiaMore

  13. Acquiring Information Technology

  15. Hardware Computer hardware can be purchased from a number of sources. They include: Computer manufacturers Distributors Retail stores Value added resellers Powered by DeSiaMore
  16. Software Software can be developed from scratch, purchased as a package, or purchased and then modified. Sources include: Developed or modified In-house programmers Contract programmers Powered by DeSiaMore
  17. Software (cont’d.) Purchased Computer manufacturers Software companies Retail stores Value added resellers Powered by DeSiaMore
  18. Networks Technology for networks can be acquired from a number of sources. They include: Network companies Computer manufacturers Software companies Value added resellers Telecommunications companies Value added network companies Powered by DeSiaMore
  19. Data Management Acquiring data management technology first requires a decision about the basic approach to data management. Sources include: Computer manufacturers Software companies Database software companies Powered by DeSiaMore
  20. Personnel and Training Managers can select personnel from inside the organization or hire from the outside. Training departments with full-time instructors provide courses and other forms of training. Computer Based Training (CBT) software is used to train users online. Powered by DeSiaMore
