Chapter 5— Systems Development and Program Change Activities TRUE/FALSE 1. The objective of systems planning is to link systems projects to the strategic objectives of the firm. ANS: T PTS: 1 2. The Systems Development Life Cycle (SDLC) concept applies to specific applications and not to strategic systems planning. ANS: F PTS: 1 3. An ant’s responsibility in the SDLC is to ensure that the system applies proper ing conventions and rules and possesses adequate control. ANS: T PTS: 1 4. In the conceptual design phase of the Systems Development Life Cycle (SDLC), task force are focused on selecting the new system design. ANS: F PTS: 1 5. When determining the operational feasibility of a new system, the expected ease of transition from the old system to the new system should be considered. ANS: T PTS: 1 6. One-time costs include operating and maintenance costs. ANS: F PTS: 1 7. When preparing a cost-benefit analysis, design costs incurred in the systems planning, systems analysis and conceptual design phases of the Systems Development Life Cycle are relevant costs. ANS: F PTS: 1 8. A tangible benefit can be measured and expressed in financial . ANS: T PTS: 1 9. Instead of implementing an application in a single big-bang release, modern systems are delivered in parts continuously and quickly ANS: T PTS: 1 10. When the nature of the project and the needs of the permit, most organizations will seek a pre-coded commercial software package rather than develop a system in-house. ANS: T PTS: 1 11. All of the steps in the Systems Development Life Cycle apply to software that is developed in-house and to commercial software. ANS: F PTS: 1 12. Mixing technologies from many vendors improves technical feasibility. ANS: F PTS: 1 13. The first step in the SDLC is to develop a systems strategy ANS: T PTS: 1 14. System maintenance is often viewed as the first phase of a new development cycle. ANS: T PTS: 1 15. During the detailed feasibility study of the project, the systems professional who proposed the project should be involved in performing the study. ANS: F PTS: 1 16. Recurring costs include: hardware maintenance, software acquisition, software maintenance, insurance, supplies, personnel costs. ANS: F PTS: 1

17. The payback method is often more useful than the net present value method for evaluating systems projects because the effective lives of information system tend to be short and shorter payback projects are often desirable. ANS: T PTS: 1 18. Intangible benefits are not physical, but can be measured and expressed in financial . ANS: F PTS: 1 19. Legal feasibility identifies conflicts between the proposed system and the company’s ability to discharge its legal responsibilities ANS: T PTS: 1 20. Programs in their compiled state are very susceptible to the threat of unauthorized modification. ANS: F PTS: 1 21. Maintenance access to systems increases the risk that logic will be corrupted either by the accident or intent to defraud. ANS: T PTS: 1 22. Source program library controls should prevent and detect unauthorized access to application programs. ANS: T PTS: 23. The test and acceptance procedure is the last point at which the can determine the system’s acceptability prior to it going into service. ANS: T PTS: 1 24. The presence of a SPLMS effectively guarantees program integrity. ANS: F PTS: 1 25. Firms with an independent internal audit staff may conduct tests of the system development life cycle on an ongoing basis. ANS: T PTS: 1 MULTIPLE CHOICES 1.
