Exam 8: Managing Projects

Assuming a beta distribution is being used,if the most pessimistic time for an activity increases by 6 weeks,what will happen to the expected time for that activity?

Table 3.6 Activity Immediate Predecessor(s) Time (weeks) A \@cdots 3 B \@cdots 9 C \@cdots 10 D A 4 E B 12 F C 5 G B,D 6 H E,F 7 I H 8 -Using Table 3.6,what is the earliest completion time of the project?

Table 3.9 All activity times for the project are in weeks. Activity Optimistic Time Most Likely Time Pessimistic Time Immediate Predecessor(s) A 3 4 5 \@cdots B 5 7 9 - C 2 3 10 A D 2 5 8 B E 1 7 7 B F 3 5 7 C,D G 7 8 9 D,E H 2 6 10 F -Using Table 3.9,if the expected time for activity E is changed to 9 weeks,by how many weeks will the projects expected completion time increase?

A(n)________ depicts the relationships between activities,which consists of nodes (circles)and arcs (arrows).

The difference between the earliest start (ES)and the earliest finish (EF)times for any activity in a project network is the

The ________ is the probable time required to perform an activity.

For controlling projects,the Schedule Performance Index (SPI)equals the cost of the work that was scheduled to have been completed by a particular date based on the original budget and project plan.

In controlling projects,the term close out refers to the decision to terminate a project because the actual time required to complete the project was going to exceed the completion date established in the original project plan.

All activities on the critical path must be crashed,or expedited,in order to reduce the overall project completion time.

Table 3.10 You are responsible for managing a project with the following activities (times are given in weeks). Activity Optimistic Time Most Likely Time Pessimistic Time Immediate Predecessor(s) A 2 5 14 \@cdots B 8 11 14 \@cdots C 5 7 9 A D 6 9 12 A E 1 3 5 D,B -Using Table 3.10,which activity has the largest slack,and how large is that slack?

Projects have a life cycle that consists of four parts.

If the sum of the variances on the critical path (and all other network paths)is equal to zero,what is the probability that the project will be completed by its earliest expected completion date?

Activity slack is the maximum length of time that an activity can be delayed without delaying the entire project.

________ is an attempt to reduce the peaks and valleys in resource needs by shifting the schedules of conflicting activities within their earliest and latest start dates.

Following are four sets of most optimistic,most likely,and most pessimistic times (in weeks)for an activity.Which one of the four sets will have a mean estimated time equal to the most likely time?

In monitoring a project,negative slack indicates how much an activity has been pushed beyond its planned latest start dates.

To obtain the latest start and latest finish time,we must work forward through the network.

Activities on the critical path have zero slack.

Table 3.2 Time (days) Activity Immediate Predecessor(s) Most Optimistic Most Likely Most Pessimistic A \@cdots 2 4 6 B \@cdots 1 4 7 C A 2 2 2 D B 1 7 10 E D 2 4 6 F E 1 2 3 G C 3 4 17 H D, G 3 7 11 I D 8 9 10 J F,H 4 5 6 K I 1 1 1 -Using Table 3.2,if the project is due to be completed in 28 days,what is the probability that the project will be completed on or before the due date? You will need to refer to a standard normal table to answer the question.

A(n)________ is an interrelated set of activities that have a definite starting and ending point and that result in a unique outcome for a specific allocation of resources.
