Which of the following is a benefit if they use the four-model approach? a. It will take less time to build a logical and physical model of the current system. b. It will not require additional expenditures to develop logical and physical models of the current system. c. It will provide a clear picture of current system functions before any modifications or improvements are made. d. It will provide time to create the current system models even for projects with tight schedules. ANSWER: c RATIONALE: The major benefit of the four-model approach is that it provides a clear picture of current system functions before any modifications or improvements are made.

If they make use of the four-model approach, which is a likely outcome? a. The time required to develop the model will increase. b. Costs of developing a logical and physical model of the current system will decrease. c. It will not be possible to get a clear picture of the current system functions before modifications are made. d. The requirements of a new information system will always be different from those of the current information system. ANSWER: a RATIONALE: The time required to develop the model increases if the four-model approach is used.
