Chapter 3, Problem 28P
Assume that the activities in Problem 3.15 have the following costs to shorten: A, $300/week; B, $100/week; C, $200/week; E, $100/week; and F, $400/week. Assume also that you can crash an activity down to 0 weeks in duration and that every week you can shorten the project is worth $250 to you. What activities would you crash? What is the total crashing cost?

If the company wants to complete the project in 40 weeks,which activities should be crashed? Calculate the additional costincurred to complete the project in 40 weeks.
For this assignment, you will design a risk management plan for a project titled “prolonged waiting times for patients in a large outpatient hospital” that will include the following elements:
Risk Register/Matrix (list of at least 5 (five) risks along with the associated impact and probability scores along with risk score)
Contingency plan (list of any risks you will plan for in advance along with what triggers the contingency).
Be sure to include any information useful to stakeholders on the rationale for the creation of these elements as well as any outside references supporting the risk management plan.
Using your results from Problem 6,(a) Calculate the probability that the project will be completedin 38 weeks.(b) Calculate the probability that the project will be completedin 42 weeks

- Project crashing is when you shorten the duration of a project by reducing the time of one or more tasks. Crashing is done by increasing the resources to the project, which helps make tasks take less time than what they were planned for. Of course, this also adds to the cost of the overall project. Therefore, the primary objective of project crashing is to shorten the project while also keeping costs at a minimum. What are the different options for crashing an activity when resources are not constrained ?arrow_forwardHi, I need help answering the last question. Rob Smith is managing a small project at Boston University. He is under pressure to shorten the overall duration of the project by 4 weeks and he wants to do so at the lowest cost possible. In order to meet this objective a number of activities must be crashed. Activity Normal Time (weeks) Crashed Time (weeks) Normal Cost Crashed Cost Predecessor(s) A 5 3 $800 $1,200 - B 6 5 $300 $450 - C 6 5 $550 $775 - D 3 2 $750 $950 A E 6 3 $1,350 $2,250 C F 5 3 $675 $875 B What is the total cost of crashing the project 4 weeks (just the additional cost, not total project cost)? (Display your answer to two decimal places.)arrow_forwardWhich of the following activities has the highest crash cost per week?
