Chapter 19, Problem 8PA
A project consists of three tasks: A, B, and C. Task A is known to take five days for sure. Tasks B and C are each dependent on A. B takes five days. C takes seven days with a probability of 0.5 and three days with a probability of 0.5. What is the expected completion time of the project?
- a. 8 days
- b. 10 days
- c. 11 days
- d. 12 days

A project has the following risks.
40% chance of schedule delay costing $3,000
20% chance of success of a new methodology saving $4,000
a 50% chance of a legal obligation which costs $3,000
a 50% chance of unexpected savings of $10,000
What is the expected monetary value of this project?
$20,000
$8,000
-$1,400
$3,100
Given a project with three paths and their corresponding path lengths: A-B-C: 25 days, A-D-F: 15 days, and B-C-D-E: 20 days; which of the following statements is TRUE? *
Activity B has the most slack
The expected duration of the project is 60 days
The earliest project completion time is 15 days
The critical activities are A, B and C
You manage a project with 10 activities. Activities A1, A3, A5, and A9 form the critical path.Because you have a large budget for the project, you consider crashing activity A2, which hasthe potential to shorten the time of A2 by three days. What do you think about this opportunity?a. It is a good idea because it will reduce the project duration by three days.b. It is a bad idea because A2 is not on the critical path.

- 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_forwardIf Activity C has an expected time estimate of 8 days, which of the following statements is TRUE? * The activity time estimates for Activity C are: 1, 7, and 19 days Activity C can be delayed for a maximum of 5 days Activity C should not be delayed The activity time estimates for Activity C are: 2, 4, and 9 daysarrow_forwardNINETEEN.

(3 points)arrow_forwardWhich of the following statements is correct with respect to slack time?a. The slack time of an activity is the latest completion time of the activity minus theearliest completion time.b. The slack time of an activity is the latest start time of the activity minus the earliest start time.c. The slack time of an activity determines how long an activity can be delayed withoutimpacting the overall completion of the project.d. All of these statements are correct.arrow_forwardActual Costs for a project so far are $50,000, and the Estimate to Complete is $50,000.

- Consider a project with four activities. Activities A1, A2, and A3 all can start immediately.However, A4 requires the completion of A1, A2, and A3. A1 can take any time between4 and 8 days. A2 can take any time between 2 and 6 days. A3 always takes 5 days. Inaddition to A4, which activity (or activities) has the potential to be on the critical path?a. A1b. A1 and A2c. A2 and A3d. A1, A2, and A3e. None of these options is correctarrow_forwardThe use of probability curves to describe a project estimate helps to deal with: Your answer: The impact of uncertainty on demand.

- Managing a project may be challenging, particularly when many departments must collaborate. When each department works on a project, they'll almost certainly employ a technique that they're most familiar with to get the outcomes they desire. Due to variations in approach and technique, this might make project cooperation across departments challenging. When working on a bigger project with multiple moving elements that must finally coordinate, project problems might arise. The project will slow down, become less productive, and potentially grind to a standstill if these pieces are not properly aligned. Project integration management is used to bring together the many departments and aspects of a project. Project integration management is a technique for coordinating many activities. It takes the many processes utilised in a project and ensures that they are coordinated. Making trade-offs is how project integration management does this. That implies you won't be able to have it all if…arrow_forwardWhich of the following is NOT essential for the success of a project? a. Completed by the due date. b. Completed within budget. c.
