Question 18 0 out of 5 points Consider the following table of activities A through G in which A is the start node and G is the stop node. Activity Duration (days) Predecessor A 5 -- B 8 A C 7 A D 6 A E 9 B, C, D F 10 B, C, D G 5 E, F Draw the network above to determine the following. What is the duration of the critical path? What is the late start time for activity E (how late can activity E start?)? a. 28 | 14 b. 28 | 12 c. 29 | 14 d. 29 | 15

a Response Feedback: Incorrect. A path is a sequence of activities that takes you from the start node (activity) through the stop node (activity). All paths through the network have to be completed. There are six paths through this network. The one that takes the longest to complete is the one that determines the duration of the project. The longest path is, by definition, the critical path. All activities on the critical path are called 'critical activities.' All critical activities have zero slack. The duration of the critical path is also the early finish time and late finish time of the stop node. The backward pass determines late finish and late start times for all activities. A backward pass starts with the late finish time (which, by convention, is always equal to the early finish time) of the stop node and works backward. The late finish time for activity E is 23. We subtract the duration of activity E from 23 to arrive at the late start time for activity E, which is 14.

Question 14 5 out of 5 points A project leader's boss has told Jonathan that his project is very important. If the critical path is delayed, he will be given whatever he needs to get the project back on schedule. His project is classified as ________ constrained. Answers: a. time b. cost c. resource d. performance e. quality

a Response Feedback: Correct. A time-constrained project is one that must be completed by an imposed date. If required, resources can be added to ensure the project is completed by a specific date. Although time is the critical factor, resource usage should be no more than is necessary and sufficient.

Question 20 5 out of 5 points Select the most accurate statement with regards to the Critical Path Method (CPM). Answers: a. It assumes that activities are independent of one another, with clearly defined start and finish dates. b. It accounts for the interruptions that may affect an activity between the start and the finish times. c. It allows us to investigate the effects of uncertainty of activity times on project completion times. d. It uses the variance in the critical path activities to evaluate the risks associated with project completion times.

a Response Feedback: Correct. CPM assumes that activities are independent of one another, with clearly defined start and finish dates. Understanding the critical path is vital to managing a project because any delays of activities on the critical path will delay the entire project.

Question 3 5 out of 5 points The district magistrate of Arkham City has decided to rebuild the busiest road in the city. She plans to close the street for the duration of the work, causing immense inconvenience to the people who typically use the road. The project has 3 parallel paths defined as the following: Path A-B-C-H will take 16 days. Path A-F-G-H will take 22 days. Path A-D-E-H will take 30 days. Given the information on hand, which of the following statements is true? Answers: a. Path A-D-E-H is the critical path. b. Path A-F-G-H has the largest slack time. c. Path A-F-G-H is the critical path. d. Path A-D-E-H has the largest slack time.

a Response Feedback:Correct. In the given scenario, path A-D-E-H is the critical path. The critical path is the sequence of activities that takes the longest time and defines the total project completion time.

c Response Feedback: Correct. Below is the early start schedule for the given project represented using a Gantt chart. Activity Immediate Predecessor(s) Activity Time(in weeks) ES EF LS LF A None 1 0 1 1 2 B None 1 0 1 0 1 C A 4 1 5 2 6 D B 5 1 6 1 6 E C, D 5 6 11 6 11 F E 3 11 14 11 14 G F 2 14 16 14 16 Activities A and B can begin at time 0 and have durations of one week each. Activity C cannot begin until activity A is completed, and activity D cannot begin until activity B is completed thus, these activities are scheduled to begin at time 1. Activity C is completed at time 5, but activity E cannot begin until activity D is also complete. Once activity D is complete, activity E can begin at time 6. Activity F can then be scheduled at time 11, and activity G can be scheduled at time 14. Activity G finishes at time 16. Thus, the earliest completion time for the given project is 16 weeks.
