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.
If you are working on the project for Company ‘B’, then please write at least 6 major Risk factors, you can foresee, that may arise during the execution of the project. You are also required to recommend the risk mitigation (risk control) steps against each risk.
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 ?

- Hi, 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_forwardGiven a project with the following characteristics, answer the following questions:You are the project manager of a project to build fancy birdhouses.You are to build two birdhouses a month for 12 months.Each birdhouse is planned to cost $100.Your project is scheduled to last for 12 months.It is the beginning of month 10. You have built 20 birdhouses and your CPI is 9091. a. Assuming that the COST variance experienced so far in the project will continue, how much more moneywill it take to complete the project? b. If the variance experienced so far were to stop, what is the project's estimate at completion?arrow_forwardWhich of the following activities has the highest crash cost per week? В F f you wanted to shorten the overall duration of the project, which activity should you crash first? E A C What is the total cost of crashing the project from its current duration down to 13 weeks? Number What is the total cost of crashing the project from its original duration to 11 weeks?

- Calculate the cost budget for the project below with a contingency reserve of 20% is applied to the cost estimate and 4% management reserve is applied to the cost baseline. Control Account Cost /$ Project Management 1,000,000 Design 4,000,000 Execution 10,200,000 Certification 600,000 Marketing 4,500,000 Launch 320,000 You have a budget at completion of $2500. You had planned to have $2200 worth of work accomplished by now. However, you have just found out that you are only 60% complete with the task. What is your SV? A project was budgeted at $1,000,000. Meanwhile, the project is executed, and the following current figures have been assessed: PV: $500,000 EV: $450, 000 AC: $550, 000 Assuming that the cost variance was…arrow_forwardYou are conducting a small IT project. The duration of this project is 30 days, and you have allocated $60,000 for it. Your manager asked you to check how the project is doing financially at the end of day 25. You have spent $40,000 and completed 95% of the work. Calculate the following values for the project so far. The cost variance (CV). The cost performance index (CPI). How is the project doing, is it under budget or over budget? Use the CPI to calculate the estimate at completion (EAC) for this project. Is the project performing better or worse than planned?arrow_forwardTwo new Internet site projects are proposed to a young start -up company. Project A will cost $250,000 to implement and is expected to have annual net cash flows of $75,000. Project B will cost $150,000 to implement and should generate annual net cash flows of $52,000. The compnay is very concerned about their cash flow. Using the payback period, which project is better, from a cash flow standpoint?arrow_forward
- You manage a multidisciplinary project team involved in the implementation of a comprehensive and complex Enterprise Resource Planning (ERP) system. The team will be working together for the next 12 months. The project goals are demanding. You are very concerned about how to keep the team motivated for the duration of the project. Discuss your strategies to keep the team motivated, and how to sustain the motivation for the duration of the ERP project.arrow_forwardCreate a risk matrix in the style of Figure 17.13 for this project. Use a vertical scale of $0 to $80.Which event should the project manager be most concerned about?Event Probability Cost ($000)1 .25 152 .35 253 .20 554 .80 105 .10 776 .40 557 .60 50arrow_forwardWhat is the total crashing cost?arrow_forward
- A project consists of three tasks: A, B, and C. Task A is known to take five days forsure. Tasks B and C are each dependent on A. B takes five days. C takes seven dayswith a probability of 0.5 and three days with a probability of 0.5. What is the expectedcompletion time of the project?a. 8 daysb. 10 daysc. 11 daysd. 12 daysarrow_forwardYou have a project to be completed in 12 months, and the total cost of the project is 100,000 USD. Six months have passed and 60,000 USD has been spent, but on closer review you find that only 40% of the work has been completed so far. Your project is expected to perform with the same cost performance. Find the Estimate to Complete (ETC) and EAC for this project.arrow_forward1arrow_forward
