CHAPTER 13 Project Management TRUE/FALSE 13.1 PERT and CPM are quantitative analysis tools designed to schedule and control large projects. ANSWER: TRUE 13.2 PERT is a deterministic analysis tool allowing for precise times of activities within a project. ANSWER: FALSE 13.3 PERT had its beginnings in a military department of the United States. ANSWER: TRUE 13.4 CPM is a probabilistic analysis of managing a project. ANSWER: FALSE 13.5 An event is a point in time that marks the beginning or ending of an activity. ANSWER: TRUE 13.6 A network is a graphical display of a project that contains both activities and events. ANSWER: TRUE 13.7 The optimistic time is the greatest amount of time that could be required to complete an activity. ANSWER: FALSE 13.8 PERT is a network technique similar to CPM, but PERT allows for project crashing. ANSWER: FALSE 13.9 The most likely completion time of an activity is used to represent that activitys time within a project. ANSWER: FALSE 13.10 The expected completion time and variance of an activity is approximated by the normal distribution in a PERT analysis. ANSWER: FALSE 13.11 PERT was developed for a project for which activity or task times were uncertain. ANSWER: TRUE 13.12 CPM was developed for use in managing projects which are repeated and about which we have good information as to activity or task completion times. 148 Project Management l CHAPTER 13 ANSWER: TRUE 13.13 With PERT, we are able to calculate the probability of finishing the project on a particular day. ANSWER: TRUE 13.14 With CPM, we are able to calculate the probability of finishing the project on a particular day. ANSWER: FALSE 13.15 A PERT or CPM network shows activities and activity sequences. ANSWER: TRUE 13.16 One of the most difficult aspects of using PERT is defining the activities so that they have measurable/observable starts and finishes. ANSWER: TRUE 13.17 Before drawing a PERT or CPM network, we must identify each activity and their predecessors. ANSWER: TRUE 13.18 The three time estimates employed in PERT are: optimistic time, average time, and pessimistic time. ANSWER: FALSE 13.19 In the PERT process, if an activity has zero variance it must be on the critical path. ANSWER: FALSE 13.20 Given the variability of the activity completion time, the original critical path we identify in our PERT analysis may not always be the actual critical path as the project takes place. ANSWER: TRUE 13.21 In PERT, the activity completion times are modeled using the beta distribution. ANSWER: TRUE 13.22 In PERT, the earliest finish time in one activity will always be the earliest start time of the following activity. ANSWER: FALSE 13.23 In PERT, the earliest start time for an activity is equal to the latest of the earliest finish times of all of its immediate predecessors.... View Full Document
