9. © 2001 Business & Information Systems 2/e9 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.

10. © 2001 Business & Information Systems 2/e10 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

11. © 2001 Business & Information Systems 2/e11 Planning for Information Systems and Technology (cont’d.) Planning involves evaluating risk. Risk is often related to three factors: 1.Size of the system development project. 2.Familiarity of the business with information technology used in the new system. 3.Amount of structure in the systems development process.

12. © 2001 Business & Information Systems 2/e12 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.
