ACC - Chapter 13 Developing and Implementing Effective Assignment




Question;Chapter 13 Developing and Implementing EffectiveAccounting Information SystemsTrue-False Questions:1.The first stage in the systems development life cycle is analyzing the companyscurrent system.2.The first stage in the systems development life cycle is planning the systems studyitself.3.Most systems development life cycles consist of mutually exclusive activities, withlittle overlap between the stages.4.Accountants do not have to worry much about systems studiesthey are rarelyaffected by them.5.The search for more efficient ways to serve customers is an important reason whybusiness organizations perform systems studies.6.One way to help ensure a systems study uses a broad point of view is to assemblean interdisciplinary study team.7.A study team should approach a systems study with a narrow point of view in orderto 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 areaso that they can work together well.9.An important first step in the systems analysis phase of a systems study is apreliminary investigation of the system under study.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 thereal cause of the problem.12.Analysis paralysis means analyzing a system to death at the expense of reachinga 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.It is not important to satisfy top management goals when creating a new informationsystem because most such systems are used by operating employees, not topmanagers.TB 13.115.The information needs of top managers tend to be the most detailed, and focus onshort range planning and budgeting.16.The information needs of operating managers are normally easier to determine thanthose of top managers because their decision making tends to be better defined andnarrower in scope.17.Studies of AIS outputs should not be concerned with non-monetary figurestheseare mostly irrelevant to accountants.18.Employee behavioral problems are rarely important in systems analysis and designwork because most systems are computer-based, not human-based.19.Systems survey work might include gathering data on an existing information systemor observing the current system in operation.20.An important deliverable from the analysis portion of a systems study is the finalsystems analysis report, which should be sent to the companys steering committee.21.An example of legal feasibility is whether or not a proposed computer system cancomply with state and federal statutes.22.A schedule feasibility evaluation is not conducted by a study team if a companyalready has an automated system.23.Schedule feasibility refers to whether or not computer vendors can provide bids in atimely manner.24.Unless the human element of a systems change is considered, the best designedsystem "on paper" will often be an operational failure when it is implemented.25.In designing an AIS, system developers should design the outputs of the systemfirst, not the inputs.26.The term cost/benefit is most closely associated with the economic feasibility of aproposed accounting information system.27.For a system to be totally feasible, all feasibility areas must be considered in theprocess.28.Prototyping is an approach to systems design whereby a design team develops asimplified shell of working software for a proposed information system.29.An advantage of prototyping is that models are usually developed without the aid ofa computer.30.When comparing computer vendor proposals, the reputations of these vendorsshould also be evaluated.31. In selecting a vendor finalist, a steering committee can use a point-scoring analysis toevaluate the proposals of alternate computer vendors.TB 13.232.Systems study work ends when the follow-up analysis shows that no furtheradjustments need to be made to the newly implemented system.33.The implementation and initial operation phase of a systems study is also known asthe "action" phase of a systems study.34.One implementation problem is installing a new system that is not adequatelydocumented or tested.35.PERT is an acronym for Project Expert and Resource Technique.36.The purpose of PERT is to coordinate the activities in a project, such as a systemsimplementation project.37.One thing that can go wrong during systems implementation is implementing asystem that has not been completely tested.38.A PERT network diagram reflects the logical sequence of systems implementationactivities.39.The slack time for a PERT activity represents the amount of time the activity can bedelayed without delaying the entire project.40.The critical path represents the most time-consuming path through a PERT networkdiagram.41.Gantt charts are the same as PERT charts.42.Project management software allows users to perform what-if analysisforexample, to determine how different work schedules might lower the time to install anew computer system.43.Controls are rarely established during the implementation of a new computer systemthis must wait for the first audit of the system.44.During systems implementation, converting computer files is only necessary if thefiles are currently in manual formats.45.A turnkey computer system is a complete set of computer hardware and softwarethat allows the user to avoid technical decisions and to begin operating quickly.46.Parallel conversion and direct conversion methods for testing a new system are quitesimilar.47.As part of the systems follow-up work, an implementation team can watchemployees perform their work activities to ascertain whether the employees areexecuting their assigned job functions correctly.48.At the conclusion of the initial follow-up study, a project leader will prepare a reportcalled a post-implementation review report.TB 13.349.The tasks involved in systems maintenance are normally performed by externalvendors, and rarely by a companys internal information systems department.50.When using outsourcing, a company needing data processing services hires anoutside organization to handle all or part of these services.51.A possible advantage of outsourcing is that it frees corporate assets for otherprojects.52.Outsourcing can help a company avoid seasonal fluctuations in its business.53.Outsourcing facilitates downsizing.54.A disadvantage of outsourcing is that a company can lose control of its IT systemsand data processing.Multiple-Choice Questions:55.An intensive investigation of a company's present information system in order todiscover systems weaknesses is termed a:a)Systems studyb)Systems follow-upc)Systems designd)Systems survey56.Which of these is not a phase in the life cycle of an information system?a)Planningb)Analysisc)Controld)Implementation57.The four phases of the systems development life cycle end with this phase:a)Analysisb)Designc)Implementation, follow-up, and maintenanced)Development58.Which of these is most likely to be the first task in a systems study?a)Systems analysisb)Systems designc)Preliminary investigationd)any of these are possibleit depends upon the system under study59.According to the chapter, which of these comes closest in meaning to the termsystems approach?a)Narrow point of viewb)Broad point of viewc)Focus on achieving those goals important to computerized systemsd)Focus first and foremost on computerizationTB 13.460.Which of the following is least likely to be a member of a study team?a)CEO of a companyb)Internal auditor or accountantc)IT specialistd)Middle-level manager who uses the system61.Which of these statements is true?a)Accountants need not bother with systems studiesthey are mostlyperformed by IT specialistsb)System studies enable bright accountants to express ideas forimproving a systemc)Systems studies rarely involve accounting information systemsd)all of these are true62.A poorly-planned information system can result in:a)Employee resistance and even sabotageb)Inflexible systems that are hard to maintain or modifyc)Systems that solve the wrong problemsd)all of these63.A waitress brings cold food to a customer, who complains.

The design team attempts to assess whether the anticipated benefits of the systemexceed its projected costsC. Systems work where the design team determines the practicality of alternativeproposalsD. This phase of a systems study requires the design team to estimate how long it willtake a new or revised system to become operationalE. Software that interfaces with suppliers and customersF. Software from independent vendors that comes bundled (i.e., combined) withhardwareG. Includes an enterprise system, any specialized information systems, or otherseparate systems for functional areas such as accounting, marketing, and humanresourcesH. The longest-path to project completion and also the shortest completion time of theentire projectI. Conversion to a new system where the new system is implemented in stagesJ. A scaled-down, experimental version of a nonexistent information system that adesign team can develop cheaply and quickly for user-evaluation purposesK. A new or revised system should comply with all applicable federal and state statutesabout financial reporting requirements, as well as the companys contractualobligationsL. For this phase of the system study, the design team must analyze the capabilities ofcurrent employees to perform the specific functions required by each proposedsystem and determine to what extent employees will require specialized trainingM. A project leader first prepares a list of systems implementation activities, identifiesthe prerequisite activities that must be completed before others can start, andestimates the amount of time required to complete each activityN. The most difficult issue in implementing a new systemO. The phrase used to describe delays in meeting the schedule for delivering a systemsprojectP.
