Textbook Question
Chapter 19, Problem 11PA
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 has the 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.

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.
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
Which activities or tasks are crucial to the project-that is, which activities will cause the entire project to be delayed if they are delayed?

- Based on the diagram in question 3, what happens to the project duration if Activity C is done at the same time as Activity D? The duration is shortened by 1 day The duration is lengthened by 1 day The duration is shortened by 4 days The duration is not affectedarrow_forwardA 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.

- 6C. Change the time of at least two activities that can reduce the overall project duration, draw the new critical path and the new Gantt chart. First: Repeat 6B by changing the task time of any 2 or 3 tasks that will result in a smaller project duration. Please note that changing only terminal tasks (ending tasks) will not give you any credit as it is easy to reduce the duration of the project by changing the duration of the last task. To make the reduced task time more visible you can colour them RED and write about them. Second: identify the critical part and explain it. Explain if the critical path has changed and why? or why not? Third: Explain your answer for the new (shorter) project duration. This can be done by describing the process and the observations done once the answer has been found. Fourth: Draw the new project’s Gantt chart Fifth: Explain the Gantt chart by emphasizing the observations made. State your conclusions. thank youarrow_forward1. What’s the maximum amount of time that activity G can be delayed without delaying the whole project? (Whole number, no space, no commas, no decimal value). 2.What’s the maximum amount of time that activity A can be delayed without delaying the whole project? (Whole number, no space, no commas, no decimal value) 3. What’s the maximum amount of time that activity H can be delayed without delaying the whole project? (Whole number, no space, no commas, no decimal value)arrow_forwardMike and Martinez are arguing about the importance of project scope management. Mike thinks that defining the project scope as early as you can during the project life cycle is a good practice, however Martinez thinks this is a waste of valuable project time and it is best to start doing the project work and the scope will become clearer once the work has started. What would be your advice to Mike and Martinez? a. The project team should not skip the scope planning process because the project team is paid to plan the project scope. b. The project team should skip the scope planning process because it was not explicitly requested by the project sponsor. c. The project team should not skip the scope planning process because it provides valuable inputs into the execution and control processes of the project. d. The project team should skip the scope planning process because it is indeed a waste of valuable time and money.arrow_forward

The project is divided into three activities. The first activity is designed to solicit individual donations. It is scheduled to run the first 25 days of the project and to bring in $25,000. Even though we are 30 days into the project, we still see that we have only 90 percent of this activity complete. The second activity relates to company donations and is scheduled to run for 30 days starting on day 5 and extending through day 35. We estimate that, even though we should have 83 percent (25/30) of this activity complete, it is actually only 50 percent complete. This part of the project was scheduled to bring in $150,000 in donations. The final activity is for matching funds. This activity is scheduled to run the last 10 days of the project and has not started. It is scheduled to bring in an additional $50,000. So far, $175,000 has actually been brought in on the project.
