Chapter 6: DEVELOPING AND IMPLEMENTING EFFECTIVE ACCOUNTING INFORMATION SYSTEMS

True-False Questions:

1. The first stage in the systems development life cycle is analyzing the company's current system.

2. The first stage in the systems development life cycle is planning the systems study itself.

3. Most systems development life cycles consist of mutually exclusive activities, with little overlap between the stages.

4. Accountants do not have to worry much about systems studies-they are rarely affected by them.

5. The search for more efficient ways to serve customers is an important reason why business organizations perform systems studies.

6. One way to help ensure a systems study uses a "broad point of view" is to assemble an interdisciplinary study team.

7. A study team should approach a systems study with a narrow point of view in order to focus directly on the system and not be distracted by peripheral issues.

8. The members of a systems study team should be from the same discipline or area so that they can work together well.

10. Top management involvement is critical to the success of a systems study.

11. When a waitress delivers food late to a customer because the kitchen is backed up, the "late food" is an example of a symptom while the "kitchen being backed up" is the real cause of the problem.

12. "Analysis paralysis" means "analyzing a system to death" at the expense of reaching a conclusion.

13. The three major types of organizational goals discussed in the chapter are (1) general systems goals, (2) computer goals, and (3) salary goals.

14. "Cost" is rarely a concern in developing information system. What is more important is that the anticipated benefits of a new AIS exceed its costs.

15. In the context of systems analysis, the goal of developing a "flexible AIS" means that the system should be able to process a variety of transactions and produce a variety of outputs.

16. It is not important to satisfy top management goals when creating a new information system because most such systems are used by operating employees, not top managers.

17. The information needs of top managers tend to be the most detailed, and focus on short range planning and budgeting.

18. The information needs of operating managers are normally easier to determine than those of top managers because their decision making tends to be better defined and narrower in scope.

19. The developers of new accounting information systems should not be concerned with non-monetary figures because these are mostly irrelevant to accountants.

20. One method of studying a current AIS is to observe the system in operation.

21. Employee behavioral problems are rarely important in systems analysis and design work because most systems are computer-based, not human-based.

22. Systems survey work might include gathering data on an existing information system or observing the current system in operation.

23. An important deliverable from the analysis portion of a systems study is the final systems analysis report, which should be sent to the company's steering committee.

24. When considering the design of a new system, four types of feasibility concerns are (1) technical feasibility, (2) operational feasibility, (3) schedule feasibility, and (4) legal feasibility.

25. An example of "legal feasibility" is whether or not a proposed computer system can comply with state and federal statutes.

26. "Schedule feasibility" is not important to a study team if a company already has an automated system.

27. "Economic feasibility" refers to whether a company can afford a proposed system.

28. "Schedule feasibility" refers to whether or not computer vendors can provide bids in a timely manner.

29. Unless the human element of a systems change is considered, the best designed system "on paper" will often be an operational failure when it is implemented.

30. In designing an AIS, system developers should design the outputs of the system first, not the inputs.

31. The term "cost/benefit" is most closely associated with the economic feasibility of a proposed accounting information system.

32. For a system to be totally feasible, all feasibility areas must be considered in the
process.

33. When developing a new AIS, it is important for designers to delay developing controls for it so that they can retrofit controls after the new system is best understood.

34. When developing the specifications for a new AIS, designers begin with outputs-not inputs or processing requirements.

35. Within the context of systems design, an example of a "demand report" is one that shows anticipated demand for a new product.

36. Within the context of systems design, an example of an "exception report" is one that identifies exceptional employees, as judged by popular vote.

37. An example of a soft-copy report is one that identifies slow-moving items where demand is soft.

38. Prototyping is an approach to systems design whereby a design team develops a simplified shell of working software for a proposed information system.

39. An advantage of prototyping is that models are usually developed without the aid of a computer.

40. Within the context of systems design, the "make or buy" decision refers to whether an organization should purchase an existing system, or develop its own system.

41. Another common term for "prewritten software" is "canned software."

42. The term "RFP" stands for "reference project."

43. The term "RFP" stands for "relative forthcoming price."

44. The term "RFP" stands for "request for proposal."

45. When comparing computer vendor proposals, the reputations of these vendors should also be evaluated.

46. An alternative to developing its own AIS, an organization might consider outsourcing the processing to an external company.

47. An example of knowledge process outsourcing (KPO) is processing tax returns.

48. Knowledge process outsourcing (KPO) mainly refers to outsourcing to offshore companies in places where labor is cheap.

49. One goal that outsourcing rarely achieves is saving money.

50. In selecting a vendor finalist, a steering committee can use a point-scoring analysis to evaluate the proposals of alternate computer vendors.

51. Systems study work ends when the follow up analysis shows that no further adjustments need to be made to the newly implemented system.

52. The implementation and initial operation phase of a systems study is also known as the "action" phase of a systems study.

53. One implementation problem is installing a new system that is not adequately documented or tested.

54. PERT is an acronym for "Project Expert and Resource Technique."

55. The purpose of PERT is to coordinate the activities in a project, such as a systems implementation project.

56. One thing that can go wrong during systems implementation is implementing a system that has not been completely tested.

57. A PERT network diagram reflects the logical sequence of systems implementation activities.

58. The "slack time" for a PERT activity represents the amount of time the activity can be delayed without delaying the entire project.

59. The critical path represents the longest path through a PERT network diagram.

60. Gantt charts are the same as PERT charts.

61. Project management software allows users to perform "what-if" analysis for example, to determine how different work schedules might lower the time to install a new computer system.

62. Controls are rarely established during the implementation of a new computer system-this must wait for the first audit of the system.

63. During systems implementation, "converting computer files" is only necessary if the files are currently in manual formats.

64. A "turnkey" computer system is a complete set of computer hardware and software that allows the user to avoid technical decisions and to begin operating quickly.

67. At the conclusion of the initial follow-up study, a project leader will prepare a report called a post-implementation review report.

68. The tasks involved in "systems maintenance" are normally performed by external vendors, and rarely by a company's internal information systems department.

69. When using outsourcing, a company needing data processing services hires an outside organization to handle all or part of these services.
