ISA 387 Chapter 3 Quiz | Answered with complete solutions A Gantt chart can simplify a complex project by combining several activities into a task _____ that contains subsidiary tasks. bar network group hierarchy A _____ involves breaking a project down into a series of smaller tasks. value breakdown structure (VBS) concept breakdown structure (CBS) risk breakdown structure (RBS) work breakdown structure (WBS) When maintaining schedules, if enough _____ and frequent checkpoints exist, problems will be detected rapidly. milestones viewports activity diagrams data flow diagrams A _____ is a proactive effort to anticipate a risk and describe an action plan to deal with it. risk balance plan risk response plan risk management plan risk identification plan Critical time is the amount of time that the task could be late without pushing back the completion date of the entire project. True False False (Slack time is the amount of time that the task could be late without pushing back the completion date of the entire project.) A(n) _____ is a condition, restriction, or requirement that the system must satisfy. viewport index milestone constraint Two or more _____ depend on a predecessor task. dependent tasks ancestor tasks concurrent tasks precursor tasks Progress reports may be given verbally to immediate supervisors, management, and users. True False False (Although a progress report might be given verbally to an immediate supervisor, reports to management and users usually are written.) In most systems analysis tasks, time and people are interchangeable. False True A project manager should never develop time and cost estimates based on the resources used for previously developed information systems. True False False (A project manager can develop time and cost estimates based on the resources used for similar, previously developed information systems.) Weight is an importance value that is added to each duration estimate. True False Generally, systems analysts review the work of other systems analysts, and programmers review the work of other programmers, as a form of peer review, in structured walk-throughs. True False Project managers always must be aware of the _____, so they can monitor the vital tasks and keep a project on track. dynamic path relative path absolute path critical path A(n) _____ is a series of tasks that, if delayed, would affect the completion date of the overall project. relative path critical path dynamic path absolute path The first step in the creation of a Program Evaluation Review Technique (PERT)/Critical Path Method (CPM) chart is to _____. identify all the project tasks select the graphical planning aids to use determine the status of all tasks determine the logical order of project tasks When tasks must be completed one after another, they are called concurrent tasks. False True False (When tasks must be completed one after another, they are called dependent tasks because one depends on the other.) The task name should be unique in the project. False True False (The task name should be brief and descriptive, but it does not have to be unique in the project.) Program Evaluation Review Technique (PERT)/Critical Path Method (CPM) and Gantt charts are mutually exclusive techniques. True False False (PERT/CPM and Gantt charts are not mutually exclusive techniques, and project managers often use both methods.) System developers can initiate a formal project as early as the preliminary investigation stage, or later on, as analysis, design, and implementation activities occur. False True Often, two or more concurrent tasks depend on a single prior task, which is called a _____. beneficiary task wireframe task discrete task predecessor task Henry L. Gantt developed Gantt charts almost 100 years ago. True False In addition to tasks, every project has events, or milestones. False True _____, a human resource issue, is a possible cause of cost overruns in an organization. Inaccurate demand forecast Unrealistic estimates Inadequate training Poor monitoring of progress A _____ includes a review of a project's scope, stakeholders, budget, schedule, and any other internal or external factors that might affect the project. risk management plan debt management plan change management plan configuration management plan When a project manager first recognizes that a project is in trouble, one of the options available to the manager is _____. delaying the project deadline expanding the project requirements eliminating controls and procedures reducing the project resources In a Program Evaluation Review Technique (PERT)/Critical Path Method (CPM) chart, each rectangular box, called a task box, has five sections that contain important information about a task. False True When two or more concurrent tasks depend on a single prior task, each of the concurrent tasks is called a(n) _____. discrete task successor task antecedent task descendent task _____ can involve a modeling process called what-if analysis, which allows a project manager to vary one or more element(s) in a model to measure the effect on other elements. Trigger analysis Qualitative risk analysis Resource list analysis Quantitative risk analysis A _____ displays the same information as the Gantt chart, including task dependencies, but uses task boxes to include much more detail. semantic wireframe ring topology network diagram mesh topology _____, a free cloud-based project management tool, runs in a browser window, so there is no software to install to use it. Smartsheet Gantter Microsoft Project Apptivo If any task along a critical path falls behind schedule, the entire project will be delayed. True False A risk response plan is a proactive effort to anticipate a risk and describe an action plan to deal with it. False True The three legs of the project triangle are management, staff, and clients. True False False (The three legs of the project triangle are cost, scope, and time.) Quantitative risk analysis evaluates each risk by estimating the probability that it will occur and the degree of impact. True False False (Qualitative risk analysis evaluates each risk by estimating the probability that it will occur and the degree of impact.) Project monitoring, an activity of a project manager, _____. consists of staffing, which includes selecting the project team and assigning specific tasks to team members includes identifying and arranging project tasks and estimating completion times and costs involves the creation of a specific timetable, usually in the form of charts that show tasks, task dependencies, and critical tasks that might delay a project requires guiding, supervising, and coordinating a project team's workload _____ give the project managers an opportunity to seek input and conduct brainstorming sessions. Project review reports Project status meetings Board meetings Status reports If team members lack experience with certain aspects of the required technology, temporary help might be obtained from IT consultants or part-time staff. False True The prior experience method to make time and cost estimates works best for large projects. False True False (The experience method works best for small- or medium-sized projects where the two systems are similar in size, basic content, and operating environment.) Frederick Brooks, Jr. observed that adding manpower to a late software project makes completion faster. True False False (Frederick Brooks, Jr. observed that adding manpower to a late software project only makes it later.) A _____ represents the work that one person can complete in one day. person-work work-duration work-day person-day
