The correct answer for each question is indicated by a .
1	CORRECT		Which level of management relies on OASs?
				A) Lower managers
				B) Middle managers
				C) Top managers
				D) All of the above
				E) None of the above
			Feedback: Correct: D) All of the above. All levels of an organization, including non-management personnel, utilize OAS systems.
2	CORRECT		Which level of manager is best served by an MIS?
				A) Lower managers
				B) Middle managers
				C) Top managers
				D) All of the above
				E) None of the above
			Feedback: Correct: B) Middle managers. An MIS is intended principally to assist middle managers with tactical decision-making.
3	CORRECT		Which type of information system relies on models?
				A) DSS
				B) ESS
				C) MIS
				D) TPS
				E) None of the above
			Feedback: Correct: A) DSS. A model is a mathematical representation of a real system.
4	CORRECT		Which type of information system supports strategic decision-making?
				A) DSS
				B) ESS
				C) MIS
				D) TPS
				E) None of the above
			Feedback: Correct: B) ESS. An ESS is an easy-to-use DSS made especially for top managers, specifically for assisting strategic decision-making.
5	CORRECT		Which is the third phase of the SDLC?
				A) Systems analysis
				B) Systems design
				C) Systems development
				D) Systems implementation
				E) Systems maintenance
			Feedback: Correct: B) Systems design. The objective of this phase is to do a preliminary design and then a detail design, and write a report.
6	CORRECT		Which phase of the SDLC utilizes prototyping?
				A) Systems analysis
				B) Systems design
				C) Systems development
				D) Systems implementation
				E) Systems maintenance
			Feedback: Correct: B) Systems design. Prototyping refers to building a working model of system components so that they can be quickly tested and evaluated.
7	CORRECT		Which phase of the SDLC involves acquiring any new hardware that might be required?
				A) Systems analysis
				B) Systems design
				C) Systems development
				D) Systems implementation
				E) Systems maintenance
			Feedback: Correct: C) Systems development. In addition to acquiring hardware, new software must be developed or acquired, and the system must be tested.
8	CORRECT		Which phase of the SDLC involves converting to the new system?
				A) Systems analysis
				B) Systems design
				C) Systems development
				D) Systems implementation
				E) Systems maintenance
			Feedback: Correct: D) Systems implementation. In addition, the final documentation is compiled and the users are trained during this phase.
9	CORRECT		Which phase of the SDLC involves testing the new system?
				A) Systems analysis
				B) Systems design
				C) Systems development
				D) Systems implementation
				E) Systems maintenance
			Feedback: Correct: C) Systems development. This occurs after the new hardware has been acquired, and the new software has been either acquired or developed.
10	CORRECT		Which method of conversion to a new system is the highest risk and the lowest cost (assuming all goes well)?
				A) Direct
				B) Parallel
				C) Phased
				D) Pilot
				E) None of the above
			Feedback: Correct: A) Direct. It costs virtually nothing unless something goes wrong, which is frequently the case.
