Concept explainers
Interpretation: Duration of the task is to be determined.
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.
Late start time: The late start time of a task can be computed by subtracting task time and late finish time of the project.
Late finish time: The rule for late finish time of a task is that it is equal to the smallest late start time of the task’s immediate follower.

Practical Operations Management
- Mohammed is planning to renovate his house garden; he is wondering how long it may take him to achieve this project so he asked his friends who went through the same project. Ahmed told him it will take 7 days, Faisal told him it will take 10 days and Salem told him it will take 15 days. How long it will take Mohammed to renovate his garden following the Beta distribution?arrow_forwardA certain task is expected to take 24 days.The employees in charge worked diligently on the task for 24 days,but he or she accomplished only three-quarters of what is required to be done.The entire project was planned to be completed in 120 days. 1- calculate the task weight for this task. 2-The actual % completion for this task. 3-The actual relative % completion for this task.arrow_forwardSuppose the optimistic estimate for completing a particular task is 2 weeks, the pessimistic estimate is 38 days, and the most likely estimate is 20 days. The PERT weight average estimate to complete that task will be: 14 days 20 days 38 days 22 daysarrow_forward
- If Task B is delayed by 2 days, which of the following task will be directly impacted? Task Duration Predecessor A 3 days - B 5 days A C 4 days B D 2 days B E 1 day C, D F 1 day E a. Task F b. Task C c. None of the above. d. Task E e. Task Darrow_forwardA project has a budget of $300,000 and is expected to last 10 months, with the work results and budget spread evenly across all months. The project just completed its 3rd month, the work is on schedule, and $65,000 has been spent. What is the cost variance? How efficient (in %) must work progress be to complete on time and within budget?arrow_forwardCalculate the average time it takes the employee described in the table to complete all four tasks ?arrow_forward
- During the product discovery, companies first identify list of potential projects, and then decide on which one to work. The final goal of the planing phase is generating a set of tasks that need to be performed and a sequence for them True or False?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_forwardThe total completion time is 25 days. Task A is planned to take seven days. Task B is planned to take five days. Task C is planned to take eight days. The tasks have a serial relationship. Task A takes nine days to be completed instead of seven days. What are the ES and EF times for Task B now that Task A is complete?arrow_forward
- The Cove at UP is looking to open a new location. Guillermo Santiago 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 7 B A 20 C A 34 D B 39 E C,D 6 F D 15 G E,F 33 end G 0 Guillermo 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} = LS_{D} = TS_{D} = EF_{G} = LF_{G} =arrow_forwardA lively discussion is under way at Sunrise Software, where you are a project manager. The main question is whether the person-days concept has limitations. In other words, if a task will require 100 person-days, does it matter whether two people in 50 days, five people in 20 days, 10 people in 10 days, or some other combination that adds up to 100 performs the work? Programmers Paula and Ethan seem to think it does not matter. On the other hand, Hector, a systems analyst, says it is ridiculous to think that any combination would work. To support his point, he offers this extreme example: Could 100 people accomplish a task estimated at 100 person-days in one day? Is Hector correct? If so, what are the limits in the “people versus days” equation? Taking the concept a step further, is there an optimum number of people to be assigned to a task? If so, how would that number be determined? You need to offer some guidance at the next project team meeting. What will you say?arrow_forwardJohn, Jack and Jill are project managers for Jusco Company. All three of them lead their own team, with two supervisors working under them. John’s team has 10 members, Jack has 8 members in his team and Jill has 11 members under his care. Both John and Jack completed their projects on time with the same amount of allocated budgets from top managers. But Jill didn’t manage to complete the project on time this time round. (i) Assuming all three projects have the same scale in terms of size, quality,and complexity, what can we conclude about the effectiveness and efficiency of these three project managers based on the informationabove?
