Which of the following statements regarding CPM is true? Select one : a. The critical path is that set of activities that has positive slack . B.All activities on the critical path have their ES equal to their LF. C.All activities on the critical path have their LS equal to the maximum EF of all immediate predecessors . d . The critical path is the shortest of all paths through the network e . Some networks have no critical path .
The activities necessary for the completion of a project are listed in the table below (Time in weeks). You are asked to complete the project 1 week ahead of time. You should crash Activity ________. This will incur an additional cost of $_________ .
You can accomplish any one of the following at an additional cost of $1500. If you will save $1000 for each day that the earliest completion time is reduced, which of the following actions should be taken, if any? 1. Reduce job 5 by two days. True or false 2. Reduce job 3 by two days. True or false 3. Reduce job 7 by two days. True or false
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 correct
Briefly describe 'Parkinson's Law' and 'Murphy's Law'. One sentence each. Then briefly in 3-6 sentences, please explain why these 'Laws' are relevant in project planning in regard to schedule, risk, cost, and resources (especially the 'people resource')..
Which of the following best describes a task on the critical path? Select one: a. The task with the highest planned value b. The task with the highest actual cost c. The task with the longest duration d. The task with no slack
You have just performed a PERT analysis and have found that more than one path through the project network has zero slack values. What can you conclude? a. You have incorrectly performed the analysis. b. You have multiple critical paths. c. Only one path is optimal. d. More than one path is optimal. e. The project will not be completed by the desired time.
A project is a set of activities with a defined start point and a defined end state, which pursues a defined goal and uses a defined set of resources. The question that must always be asked before a project is started is, “How is the project going to be planned and controlled?” For a project to be successful, there are 5 stages that need to be implemented. You have been appointed as the project manager for a project at you workplace to reduce downtime and you need to demonstrate your understanding of project planning and controlling by describing the 5 stages in detail and explain how you would implement it at your workplace.
b) Assuming that each task is started as soon as possible, construct the corresponding resource loading diagram for the project. c) How would you rearrange the timing of project activities to reduce the fluctuation in resource demand? Assume that the overall project duration cannot be extended. Remember that the specified precedence relationships must be maintained. d) If there are only 20 workers available for the project, how would you assign workers to tasks to ensure that the project can be completed without violating the resource limit? In this case, the project duration may be extended if necessary (but without violating precedence relationships). e) Given the results from (c) and (d) above, what recommendations would you make to senior management regarding the staffing of this project, and why?
