A project's critical path is composed of activities A, B, and C. Activity A has a standard deviation of 2, activity B has a standard deviation of 1, and activity C has a standard deviation of 2. What is the standard deviation of the critical path?PERT analysis computes the variance of the total project completion time asThe critical path of a network is theWhich of the following is a direct responsibility of the project manager?What is the probability that a project with a mean completion time of 23.9 days and a variance of 6 days will be finished in 26 days?An activity has an optimistic time of 15 days, a most likely time of 18 days, and a pessimistic time of 27 days. What is its expected time?A project's critical path is composed of activities A, B, and C. Activity A has a standard deviation of 2, activity B has a standard deviation of 1, and activity C has a standard deviation of 2. What is the standard deviation of the critical path?PERT analysis computes the variance of the total project completion time asThe critical path of a network is theWhich of the following is a direct responsibility of the project manager?What is the probability that a project with a mean completion time of 23.9 days and a variance of 6 days will be finished in 26 days?An activity has an optimistic time of 15 days, a most likely time of 18 days, and a pessimistic time of 27 days. What is its expected time?What analysis computes a variance of the total project completion time as?PERT analysis computes the variance of the total project completion time as: The sum of the variances of all activities on the critical path. What is PERT analysis based on which time?It analyzes the time required to complete each task and its associated dependencies to determine the minimum time to complete a project How is total project variance determined in CPM PERT analysis?In order to calculate the variance of the overall project, add up the variances of the activities under critical Path. Say for example Critical Path is Activity A, C, E, H. Then add up the variances of these activities to calculate the project variance.
What is the expected time and variance for activities in PERT networks?An activity on a PERT network has these time estimates: optimistic =2, most likely = 3, and pessimistic 8. Its expected time and variance (if it is a critical activity) are: The expected time and variance (if it is a critical activity) are 3.67 and 1, respectively.
Which of the following is an advantage of PERT and CPM?Both PERT and CPM are essential project management tools that divide the activities as per function and responsibility that helps in proper coordination of work with the different teams involved in the project. It allows the managers to take timely decisions that reduces delays in the completion of projects.
Which of the following is limitation of PERT and CPM?28. Which of the following is a limitation of pert and cpm? There is the inherent danger of placing too much emphasis on the critical path.
