A company wants to use CPM analysis to manage their project.One of the activities that make up the project has an uncertain duration.Three estimates have been given to determine this activity's duration.The estimates are optimistically 1 hour,most likely 5 hours and pessimistic 6 hours.Using the three activity time estimation procedure for CPM,what is the expected time this activity will take?

A) 2.5 hours
B) 3.5 hours
C) 4.5 hours
D) 5.5 hours
E) None of the above

F) B) and E)
G) All of the above

Project management software available today combines CPM and other scheduling aids,like Gantt charting,to aid in tracking progress of project completion.

What is that sequence of activities that consume the longest amount of time in a project network of activities called?

The work breakdown structure (WBS)defines a hierarchy of project tasks,subtasks and work packages.

Project Management can be defined as planning,directing and controlling resources to meet the technical,cost and time constraints of the project.

An assumption of three-activity-time CPM analysis is that the activity time estimates conform to the beta distribution.Which of the following is a valid criticism of this assumption?

Below are the data for a Time-Cost CPM Scheduling model analysis.The time is in days and the costs include both direct and indirect costs. $\begin{array}{|l|l|l|l|l|l|}\hline & \text { Immediate } & \text { Normal } & \text { Crash } & \text { Normal } & \text { Crash } \\\hline \text { Activity } & \text { Predecessor } & \text { Time } & \text { Time } & \text { Cost } & \text { Cost } \\\hline \text { A } & \text { None } & 3 & 2 & \$ 200 & \$ 400 \\\hline \text { B } & \text { A } & 4 & 3 & \$ 300 & \$ 600 \\\hline \text { C } & \text { A } & 1 & 1 & \$ 200 & \$ 200 \\\hline \text { D } & \text { B and C } & 3 & 2 & \$ 500 & \$ 550 \\\hline \text { E } & \text { D } & 2 & 1 & \$ 500 & \$ 900 \\\hline\end{array}$ What are the total time of this project and total normal cost?

A series of projects that are organized in such a way that each project utilizes people from different functional areas is using which of the following organizational structures?

A disadvantage of a matrix project organizational structure is that a project manager is held responsible for successful completion of the project.

To calculate the variances of activity times in CPM analysis we must use all three time estimates (i.e. ,optimistic,most likely and pessimistic time estimates).

The second step in managing a project is writing the Statement of Work (SOW).

In a CPM analysis if you subtract the early finish from the late finish the result is the activity's slack time.

Describe how CPM handles the trade-offs between time and cost in the scheduling of a project?

The "Z" value used to calculate the probabilities in CPM analysis is based on the Beta probability distribution.

Below are the data for a Time-Cost CPM Scheduling model analysis.The time is in days and the costs include both direct and indirect costs. $\begin{array}{|l|l|l|l|l|l|}\hline & \text { Immediate } & \text { Normal } & \text { Crash } & \text { Normal } & \text { Crash } \\\hline \text { Activity } & \text { Predecessor } & \text { Time } & \text { Time } & \text { Cost } & \text { Cost } \\\hline \text { A } & \text { None } & 3 & 2 & \$ 200 & \$ 400 \\\hline \text { B } & \text { A } & 4 & 3 & \$ 300 & \$ 600 \\\hline \text { C } & \text { A } & 1 & 1 & \$ 300 & \$ 300 \\\hline \text { D } & \text { B and C } & 3 & 2 & \$ 500 & \$ 550 \\\hline \text { E } & \text { D } & 2 & 1 & \$ 500 & \$ 900 \\\hline\end{array}$ If you crash this project to reduce the total time by one day what is the total time of the project and total cost?

A company must perform a maintenance project consisting of seven activities.The activities,their predecessors and their respective time estimates are presented below: $\begin{array}{|l|l|l|l|}\hline & & \text { Immediate } & \\\hline \text { Activity } & \text { Designation } & \text { Predecessor } & \text { Time in Days } \\\hline \text { Break down both machines } & \text { A } & \text { None } & 3 \\\hline \text { Clean machine 1 } & \text { B } & \text { A } & 3 \\\hline \text { Clean machine 2 } & \text { C } & \text { A } & 3 \\\hline \text { Re-set machine 1 } & \text { D } & \text { B } & 4 \\\hline \text { Re-set machine 2 } & \text { E } & \text { C } & 2 \\\hline \text { Re-calibrate both machines } & \text { F } & \text { D and E } & 1 \\\hline \text { Final test } & \text { G } & \text { F } & 2 \\\hline\end{array}$ Using the Single Time Estimate CPM procedure,which activities make up the critical path?

Which of the following is a graphic project report used in project management?

The critical path of activities in a project is the sequence of activities that form the shortest chain in a project network of activities.

You have just performed a Single Time Estimate CPM analysis and have found that more than one path through the project network has zero slack values.What can you conclude?
