Concept explainers
Interpretation: Duration of the project is to be calculated.
Concept Introduction: Critical path is the arrangement of project activities which gives an estimate time duration under which project will be completed. The project activities may include float activities which can be delayed focusing on the shortest time duration.
PERT diagram is a graphical project management tool used to organize and analyze project and it’s activity. It defines time duration for a project and also for each activity in a project.
Early start time: The rule for early start time of a task is that it is equal to largest early finish time of the task’s immediate predecessors.
Early finish time: The early finish time of a task is addition of both task time and early start time of the task.

- There are six processes in the project time management knowledge area. How do these processes interact in the creation of the project schedule?arrow_forwardCalculate the latest start for Task D if one of its successors, Task F, has a latest start on day 9, its other successor, Task E, has a latest start on day 10, and the duration of Task D is 2 days.arrow_forwardYou can accomplish any one of the following at an additional cost of $1500. If you will save $1000 for each day that the earliest completion time is reduced, which of the following actions should be taken, if any? 1. Reduce job 5 by two days. True or false 2. Reduce job 3 by two days. True or false 3. Reduce job 7 by two days. True or falsearrow_forward
- A project has 92 activities, but only 13 of them are analyzed here. Activity P, 9 days, IP = not given Activity W, 10 days, IP = not given Activity S, 6 days, IP = not given Activity A, 25 days, IP = P, W Activity F, 24 days, IP W, S Activity N, 21 days, IP S Activity E, 28 days, IP = A Activity M, 13 days, IP A, F Activity B, 40 days, IP N Activity H, 10 days, IP = E, M Activity K, 14 days, IP = E, M, B Activity D, 11 days, IP = B Activity R, 10 days, IP = B It has been calculated that LS(K) = 118, LS(D) = 109, LS(H) = 124, LS(R) = 116. %3D %3! %3D What is LS(A)?arrow_forwardYou have prepared the following schedule for a project in which the key resource is a backhoe. This schedule is contingent on having 3 backhoes. You receive a call from your partner, Brooker, who desperately needs 1 of your backhoes. You tell Brooker you would be willing to let him have the backhoe if you are still able to complete your project in 11 months. Develop a resource schedule to see if it is possible to complete the project in 11 months with only 2 backhoes. Activities 5 and 6 require 2 backhoes, while activities 1, 2, 3, and 4 require 1 backhoe. No splitting of activities is possible.arrow_forwardNeeded to be solved correctly in 30 minutes and get the thumbs up please show neat and clean workarrow_forward
- Activity A takes 36 hours and can begin as soon as the project begins. Activity B takes 21 hours and should take place after the project has begun. Activity C must happen after Activity A and lasts 31 hours. Activity D must take place after activities B and C takes 26 hours. Activity E must take place after Activity C and lasts 6 hours. Activity F takes place after Activity E and lasts 18 hours. Activities F and D are the project's final activities. Draw the AON for the network diagram and specify the critical path and its duration.arrow_forwardYou are currently managing multiple projects relating to a high-profile build-out of a major retail center. The project is extensive, with a two-year timeline. Jenine is the project manager responsible for the east block of the build-out, and Bei Jian is the project manager responsible for the north block of the build-out. Both Jenine and Bei Jian report to you. Your role can best be described as: lead project manager department manager program manager portfolio managerarrow_forwardPlease review this Gantt chart it should consist a minimum of 10 tasks Create a partial project schedule using a Gantt Chart (with a minimum of 10 tasks). Can you do it in excel format please Part 1 To prepare a Gantt chart for the FAO-funded Aquaponics Project in Barbados, we need to break down the project into individual tasks and then arrange them in a logical order based on their dependencies. Here is a table format Gantt chart for the project: Task Start Date End Date Duration Dependencies Project planning and initiation 01/01/2021 01/15/2021 15 days - Site selection and preparation 01/16/2021 02/15/2021 30 days Project planning and initiation Design and construction of facility 02/16/2021 04/15/2021 60 days Site selection and preparation Procurement of equipment and tools 04/16/2021 05/15/2021 30 days Design and construction of facility Training program development 05/16/2021 06/15/2021 30 days Procurement of equipment and tools Training program…arrow_forward
- Market Fresh Foods is looking to develop a new strategic plan. Jay Jones has been developing a project plan and has identified the following tasks, precedence relations, and normal task durations. tasks predecessors task duration start 0 A start 40 B A 34 C A 31 D A 38 E A 28 F C,D 18 G B,F 13 H E,G 22 end H 0 Jay has studied project management at the University of Portland and knows that the starting and ending time of any task may be determined from the information in the table using the critical path method. Assume the following notation when answering the questions below: Metric Description ES Early start time for task EF Early finsh time for task LS Late start time for task LF Late finsh time for task TS Total slack for task FS Free slack for task IS Independent slack for task SS safety slack for task Please provide the CPM result for each of the following metrics: ES_{end} = LF_{D} = FS_{D} = TS_{G} = IS_{G} =arrow_forwardsniparrow_forwardConsider a project to produce custom door moldings for GMC Acadia cross-over vehicles, described in Tablea. If you start the project immediately, when will it be finished?b. You are interested in completing your project as soon as possible. You have only one option. Suppose you could assign Employee A, currently assigned to activity G, to help Employee B, currently assigned to activity F. Each week that Employee A helps Employee B will result in activity G increasing its time by one week and activity F reducing its time by one week. How many weeks should Employee A work on activity F?arrow_forward
