Exam 5: Scheduling the Project

Milestones are not depended upon the predecessor activities in the project plan.

A diagram of nodes connected by directional arcs that defines the project and illustrates the technical of all activities is referred to as a network.

Explain why the term "critical path" has less meaning in cases where the activity times are not known with certainty.

A big advantage of AON networks is that they are easier to draw.

The amount of time a noncritical task can be delayed without delaying the project is called?

Networks are usually drawn with a "Start" node to the right and a "Finish" node to the left.

If task duration estimates are carefully made, the project manager needs to only examine the critical path when conducting a risk analysis.

The actual project duration will be known with certainty after the project is completed.

"Merger" is a term used to describe the situation in which two or more paths in a network join together.

What is a merger and what problems do mergers create?

Why is it necessary for the PM to be aware and to manage the slack in the project?

What is project slack?

A disadvantage of Gantt charts is that they are hard to draw.

What is the standard deviation of a task with optimistic, most likely, and pessimistic times of 3, 4, and 7 days respectively assuming the estimates were made at the 99% plus level?

A situation where two or more activities have the same starting and finishing nodes or where a single activity connects to two or more nodes is called a dummy task

When it was originally developed, PERT used certain (deterministic) methods to estimate activity duration.

To manage a project successfully, the project manager need only pay close attention to tasks on the critical path.

A Term not used in the discussion of PERT/CPM analysis is

What is activity slack?

Float refers to the amount of time a noncritical task can be delayed without causing a delay in the entire project.
