Any potential change in system requirements that are identified or suggested after the design phase must __________. a. go through a formal scope change process before work on them begins b. be evaluated in terms of how they might affect system performance c. require feasibility analysis d. all of the above

You and your team have been hired to perform a system investigation for a fast food restaurant that wants to implement new tools and processes to improve its customer service. Currently, the restaurant has a poor reputation for not correctly filling customers orders and for taking too long to do it. Perform a functional decomposition to define the scope and basic requirements of such a system. Brainstorm some ideas to improve the situation, and choose one to pursue based on its technical, economic, legal, operational, and schedule feasibility.

Any potential changes in system requirements that are identified or suggested after the design phase must ____________. a. go through a formal scope change process before work on them begins b. be evaluated in terms of how they might affect system performance c. require feasibility analysis d. all of the above

The purpose of the system investigation phase is to __________. a. define what the information system must do to solve the problem or capitalize on the opportunity. b. gain a clear understanding of the specifics of the problem to solve or the opportunity to address. c. gather data on the existing system and determine the requirements for the new system. d. identify, confirm, and prioritize system requirements.

A preliminary evaluation of software packages and vendors begins during the _____________ phase when the two or three strongest contenders are identified. a. system investigation b. system design c. system analysis d. feasibility analysis
