Chapter 06 - Developing a Project Plan True False

Chapter 06 - Developing a Project Plan True / False Questions 61. An activity includes only one work package. FALSE Activities usually represent one or more tasks from a work package. AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Constructing a Project Network Level: Easy 62. Project networks are built using nodes and arrows. TRUE The two approaches used to develop project networks are known as activity-on-node (AON) and activity-on-arrow (AOA). Both methods use two building blocks—the arrow and the node. AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Constructing a Project Network Level: Easy 63. The WBS identifies dependencies, the sequencing of activities, and the timing of activities. FALSE Networks provide the project schedule by identifying dependencies, sequencing, and timing of activities, which the WBS is not designed to do. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: From Work Package to Network Level: Medium 64. The critical path is the shortest path through a network and indicates activities that cannot be delayed without delaying the project. FALSE Critical path means the path(s) with the longest duration through the network; if an activity on the path is delayed, the project is delayed the same amount of time. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 6-45 Chapter 06 - Developing a Project Plan 65. An activity is an element of the project that always requires time but may or may not require resources. TRUE An activity is an element of the project that requires time. It may or may not require resources. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 66. The two approaches used to develop project networks are AOA and AON. TRUE The two approaches used to develop project networks are known as activity-on-node (AON) and activity-on-arrow (AOA). AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Constructing a Project Network Level: Easy 67. In an AOA network an activity is represented by a box. Refer to Appendix 6.1 FALSE The activity-on-arrow (AOA) approach also uses the arrow and node as network building blocks. However, in this approach the arrow represents an individual project activity that requires time. The length and slope of the arrow have no significance. The node represents an event; it is usually presented as a small circle. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 6-46 Chapter 06 - Developing a Project Plan 68. In developing a project network, each activity should have a unique identification number that is smaller than the identification numbers of activities that follow it. TRUE Each activity should have a unique identification number. And that activity identification number must be larger than that of any activities that precede it. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 69. In developing a project network, neither looping statements nor conditional statements are permitted. TRUE Looping is not allowed (in other words, recycling through a set of activities cannot take place). Also Conditional statements are not allowed (that is, this type of statement should not appear: If successful, do something; if not, do nothing). AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 70. Experience suggests that when there are multiple starts, a common start node should not be used to indicate a clear project beginning on the network. Similarly, a single project end node can be used to indicate a clear ending. FALSE Experience suggests that when there are multiple starts, a common start node can be used to indicate a clear project beginning on the network. Similarly, a single project end node can be used to indicate a clear ending. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 6-47 Chapter 06 - Developing a Project Plan 71. Burst activities have more than one activity immediately following it (more than one dependency arrow flowing from it). TRUE Burst activities have more than one activity immediately following it (more than one dependency arrow flowing from it). AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Factors Influencing the Quality of Estimates Level: Easy 72. It is acceptable for arrows to cross one another in a network diagram. TRUE Arrows on networks indicate precedence and flow. Arrows can cross over each other. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Easy 73. The forward pass through a project network determines the critical path. FALSE The forward pass starts with the first project activity(ies) and traces each path (chain of sequential activities) through the network to the last project activity(ies). The forward pass assumes every activity will start the instant in time when the last of its predecessors is finished. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Network Computation Process Level: Medium 6-48 Chapter 06 - Developing a Project Plan 74. The backward pass though a project network determines how long an activity can be delayed without impacting the completion date of the project. TRUE The backwards pass which activities represent the critical path (CP). This is the longest path in the network which, when delayed, will delay the project and how long can the activity be delayed (slack or float—SL). AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Network Computation Process Level: Medium 75. Different activities along the same path can have different total slack. TRUE If slack of one activity in a path is used, the ES for all activities that follow in the chain will be delayed and their slack reduced. Use of total slack must be coordinated with all participants in the activities that follow in the chain. AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Network Computation Process Level: Medium 76. By definition, the critical path always has zero slack. FALSE The critical path follows activity start and finish constraints that occur due to the use of the additional relationships available and the imposed lags. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Extended Network Techniques to Come Closer to Reality Level: Medium 6-49 Chapter 06 - Developing a Project Plan 77. It is possible to have more than one critical path at the same time. TRUE Critical path means the path(s) with the longest duration through the network; if an activity on the path is delayed, the project is delayed the same amount of time. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Constructing a Project Network Level: Medium 78. Free slack applies to an entire project network. FALSE Free slack is the amount of time and activity can be delayed without delaying any immediately following (successor) activity. Or, free slack is the amount of time an activity can exceed its early finish date without affecting the early start date of any successor(s). AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Network Computation Process Level: Medium 79. Gantt charts are popular because they represent an easy-to-understand, clear picture on a time-scaled horizon. Refer to Figure 6.12 TRUE See Figure 6.12 on Page 176. AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Practical Considerations Level: Easy 6-50 Chapter 06 - Developing a Project Plan 80. Lags are used to break larger activities into smaller segments so that activities that follow can be started earlier. FALSE When activities of long duration delay the start or finish of successor activities, the network designer normally breaks the activity into smaller activities to avoid the long delay of the successor activity. Use of lags can avoid such delays and reduce network detail. AACSB: Reflective Thinking Bloom's: Comprehension Learning Objective: Extended Network Techniques to Come Closer to Reality Level: Medium 81. Only activities that occur at the end of a chain of activities can have free slack. TRUE Free slack occurs at the last activity in a chain of activities. In many situations the "chain" can have only one link. AACSB: Reflective Thinking Bloom's: Knowledge Learning Objective: Network Computation Process Level: Medium 82. Lags can be use to constrain the start and finish of an activity. TRUE Lags can be used to constrain the start and finish of an activity.
