Chapter 13-Managing the Systems Development Life Cycle

TRUE/FALSE

1)The majority of the cost of a system is incurred in the new systems development phase of the life cycle.

 

 

 

2. According to the text, a stakeholder is an end user of a system.

 

 

 

3. The objective of systems planning is to link systems projects to the strategic objectives of the firm.

 

 

 

4. The Systems Development Life Cycle (SDLC) concept applies to specific applications and not to strategic systems planning.

 

 

 

5. An accountant’s responsibility in the SDLC is to ensure that the system applies proper accounting conventions and rules and possesses adequate control.

 

 

 

6. In the conceptual design phase of the Systems Development Life Cycle (SDLC), task force members are focused on selecting the new system design.

 

 

 

7. 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.

 

 

 

8. One-time costs include operating and maintenance costs.

 

 

 

9. 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.

 

 

 

10. A tangible benefit can be measured and expressed in financial terms.

 

 

 

11. Instead of implementing an application in a single “big-bang” release, modern systems are delivered in parts continuously and quickly

 

 

12. When the nature of the project and the needs of the user permit, most organizations will seek a pre- coded commercial software package rather than develop a systems in-house.

 

 

 

13. All of the steps in the Systems Development Life Cycle apply to software that is developed in-house and to commercial software.

 

 

 

14. Mixing technologies from many vendors improves technical feasibility.

 

 

 

15. The first step in the SDLC is to develop a systems strategy
16. System maintenance is often viewed as the first phase of a new development cycle.

 

 

 

17. Project initiation is the process by which systems proposals are assessed for consistency with the strategic systems plan and evaluated in terms of their feasibility and cost-benefit characteristics.

 

 

 

18. When the nature of the project and the needs of the user permit, most organizations will create the system in-house rather than rely on a commercial package.

 

 

 

19. Existing (maintained) applications are the prototypes for their new versions.

 

 

 

20. Because of the robustness of modern technology, businesses today see infrequent changes in their IT systems and much longer system life spans.
