The managers at AllBirds have operations in multiple countries, which operate on different financial management systems. This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table. Draw the project network, and compute the expected time and variance for each activity. Develop an activity schedule for this project, compute activity slack time and identify critical path.
Below is a network diagram that represents a university revamp project. The project manager analyzes this project using the critical path (CP) method. Activity durations are indicated on the network
What is the value of the missing item labeled (a) in the table above? Round to the nearest integer. What is the value of the missing item labeled (b) in table above? Round to two decimals. Draw the network diagram for this project. Clearly label the earliest start, earliest finish, latest start, latest finish and slack for each activity. Specify the critical path and the critical activities. State the expected C.P. duration State the variance of the critical path. What is the probability that the dashboard will be delivered within 20 days?
A project has 7 activities P, Q, R, S, T, U, and V. Three time estimates (optimistic, most-likely, pessimistic) are used for each activity. Write down your answers to all parts of the question in the box given below. Give your answer to 3 decimal places. (Note (a) has of 2 parts and (b) has of 3 parts) For activity Q, these time estimates are as follows: optimistic time = 9, most-likely time = 14, pessimistic time = 20. Write down the average activity time for Q the variance of activity time for Q. The critical path of this project has a mean project time of 44 days and a standard deviation of 5 days. Assume project completion time is normally distributed. Find the probability that the project will be completed in 47 days. Find the probability that the project will take more than 40 days. We want to set a deadline for this project completion. If the probability of meeting this set deadline is 0.88, what will be the deadline for this project.
Dave the critical path should also be determined.

Consider the following PERT time estimates: a. Draw a network for this project and determine the critical path based on the most likely times by inspection.b. Assuming that the critical path is the one you identified in part (a), what is the probability that the project will be completed before 28weeks? Before 32 weeks?c. Assuming that the critical path is the one you identified in part (a), how many weeks are required to complete the project with probability .95?
1. A project was planned using PERT with three-time estimates. The expected completion time of the project was determined to be 40 weeks. The variance of the critical path is 9. (e) The project manager wishes to set the due date for the completion of the project so that there is a 90% chance of finishing on schedule. Thus, there would only be a 10% chance the project would take longer than this due date. What should this due date be?
Dave Fletcher was able to determine the activity times for constructing his laser scanning machine. Fletcher would like to determine ES, EF, LS, LF, and slack for each activity. The total project completion time and the critical path should also be determined. Here are the activity times: Time Activity (weeks) 6 7 ABCO 3 2 Immediate Predecessor(s) A A D Dave's earliest start (ES) and earliest finish (EF) are: Time Activity (weeks) 4 EFGHI 6 10 7 Immediate Predecessor(s) B B C, E D,F
Canesta Company is working on a project with the following network: a) Determine the earliest and latest activity times and slack for each activity. b) Determine the duration of the project and the critical path.
The network diagram of a project with four activities is presented below. Start A B C D The estimated optimistic, most likely, and pessimistic times of each task are given in the table below. The expected time and variance of acitivities A are also given in the table. The expected time and variance of activity C and D are irrelevant in this problem. So they can be ignored. optimistic 14 4 5 5 most likely B 18 10 7 10 End pessimistic 23 18 13 12 Expected time 18.167 XX mm variance 81/36 [Three decimal places for all answers) (1) What is the expected task time of activity B?
