- Suppose that a task in a project has the following time estimates: to=optimistic completion time=10 weeks tm=most likely completion time=17 weeks tp=pessimistic completion time=19 weeks Compute the expected task variance. The task expected task variance is _____ weeks. (Enter your response rounded to two decimal places.)Liam is estimating the schedule for all activities in the GHI Project. He is working with his project team and comparing the results of a past similar project to forecast the schedule for his current project. This is an example of which estimating approach? Group of answer choices Analogous Organizational process assets Parametric PERTSuppose that a task in a project has the following time estimates: to=optimistic completion time=9 weeks tm=most likely completion time=17 weeks tp=pessimistic completion time=21 weeks Compute the expected task completion time.

- Explain the advantage of using probabilistic time estimateYou 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.l TelkomSA 11:00 A ikamva.uwc.ac.za An IT project manager of ABC Company has developed an activity list for the purpose of tracking employees' daily activities on the project. The project's schedule is considered to be of high risk due to the possibility of sabotage by some of the employees. In addition, the IT project manager has gathered time information for each activity, as shown in the table below. Consider the following project's tasks and their identified best, likely, and worst case estimates of task duration.

- You are the Project Manager of a project to set up a Telecoms Infrastructure for a company. You have two options for a resource to work on a specific installation task for your project. The task is not on the critical path, but it is somewhat complex. Your options are as follows: One choice is Kwesi. He is the most skilled Engineer in the company and is therefore in constant demand. As a result, he is usually assigned to several projects at the same time. He is available to your project on a half-time basis. He currently has commitments to two other projects for the remaining half of his time. Your other choice is a team of two Engineers, both of whom have average skills. They are recent hires into the company and have never worked together before. In this option you have two alternatives and are free to choose whichever one you want. First, you could pick one of the two average skilled Engineers to work half-time on your project. Second, they could each be assigned to your project…Limbo Technologies has embarked on another project that has an estimated completion time of 40 weeks and a standard deviation of 5 weeks. It is estimated that the project completion time is normally distributed. i)What is the probability of finishing the project in 38 weeks or less? ii)The due date for the project is set so that there is a 90% chance that it will finish by this date.

- You are in charge of a project at the local community center. The center needs to remodel one ofthe rooms in time for the start of a new program. Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-costproject schedule using below format.The AON diagram for the community center project is below. Crash 4 times and find total cost.Farihah is a project manager for a systems development project involving a new database application for her organization’s human resources department. Despite Farihah’s best efforts at estimating the time requirements for the project, the team has missed the deadline for completing the Analysis Phase and producing the System Proposal. Farihah had estimated during her 6-week Planning Phase that Analysis would require 2 months, but the team finished the System Proposal 2 weeks behind their planned target date. Based on her discussions with the team members, Farihah believes that the system is more complex than she originally thought. Should Farihah adjust her timeline, or can she try to make up for the lost two weeks? Farihah needs your advice.Using the FCFS rule for scheduling, the sequence is Sunny Park Tailors has been asked to make three different types of wedding suits for separate customers. The table below highlights the time taken in hours for cutting and sewing (process 1) and delivery (process 2) of each For the schedule developed using the FCFS rule, the total length of time taken to complete the three suits (including of the suits. delivery) = hours (enter your response as a whole number). Times Taken for Different Activities (hours) Deliver Suit Cut and Sew Using Johnson's rule for 2-machine scheduling, the sequence is 1 2. For the schedule developed using the Johnson's rule, the total length of time taken to complete the three suits 3 (including delivery) = hours (enter your response as a whole number). Assume that orders for suits have been listed in the above table in the order in which they were received. Of the two developed schedules, V rule gets the schedule finished sooner.
