Explain briefly
Select an everyday “project” you are familiar with such as a class project, preparing a meal, making a pizza, or repairing your car. Develop a list of the activities, a CPM/PERT network (with time estimates) for the project.
The following table lists the activities for a small part of a project with various durations and dependencies. Fill in the PERT Average duration column.

- Suppose you are the project manager for the following project: First, draw a network diagram for the project. Determine the critical path and slack times for all of the tasks. This completes your plan for the project schedule. During project execution, you become aware of the need to change the duration of Task 4 to five days. Meanwhile, Task 3 has been finished one day early, so it only took one day to do. What, if any, effects do these changes have on your project? What would have happened if you had not been monitoring the status of the project?arrow_forwardIn reference to the attached image: Draw the project network, and determine the normal time to complete the project, activity slack times, the critical path(s), and total project costs (i.e., baseline your project), using the Critical Path Method.arrow_forwardThe 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. What is the probability that project can be completed two months early?arrow_forward
- Discuss the ethical considerations associated with completing a project in the shortest possible time.arrow_forwardAssess the planning, monitoring, and controlling of projects using the Program Evaluation and Review Technique(PERT)/Critical Path methods(CPM), including factors such as early start late finish, duration, and precedence in the project path. Share an example of a real world application.arrow_forwardBased on the PERT diagram, where the numbers indicate days required between events, how many days would be required to complete the project (starting at A, and finishing at L with all tasks complete)?arrow_forward
- Schedule the following activities using CPM: Activity Immediate Predecessor Time (weeks) A - 1 B A 4 C A 3 D B 2 E C,D 5 F D 2 G F 2 H E,G 3 Part (a) Draw the network : Part (b) What is the critical path? Part (c) How many weeks will it take to complete the project? Part (d) What activities have slack, and how much?arrow_forwardDetermine the critical path(s) and slack time for non-critical activities for the project as shown below (time unit is “days”).arrow_forwardUsing the below table calculate critical path for the project. Which tasks are on the critical path? Task Predecessor Duration (Weeks) A - 32 B - 11 C - 12 D B,C 16 E A,B 23 F A 23 G D 22 H D 33arrow_forward
- From the following information, develop an AON project network. Complete theforward and backward pass, compute activity slack, and identify the critical path.How many days will the project take?arrow_forwardA project manager has compiled a list of major activities that will be required to install a computer information system in her firm. The list includes estimated completion times for activitiesand precedence relationships.ActivityImmediatePredecessorEstimatedTimes (weeks)A — 2-4-6D A 6-8-10E D 7-9-12H E 2-3-5F A 3-4-8G F 5-7-9ActivityImmediatePredecessorEstimatedTimes (weeks)B — 2-2-3I B 2-3-6J I 3-4-5K J 4-5-8C — 5-8-12M C 1-1-1N M 6-7-11O N 8-9-13End H, G, K, Oa. Construct a network diagram. You can use either AOA or AON (see Example 5).b. If the project is finished within 26 weeks of its start, the project manager will receive a bonusof $1,000; and if the project is finished within 27 weeks of its start, the bonus will be $500.Find the probability of each bonus.arrow_forwardUsing the attached diagram, Identify the critical path and project total duration. Identify the slack available for each task. Discuss what would happen to the critical path if task E ends up lasting 19 days instead of the 12 estimated.arrow_forward
