Project Management Chapter 6

Which of the following represents an activity on an activity-on-node (AON) project network?

A node

If a project has more than one activity that can begin when the project is to start, a common start node should be used to indicate a clear project beginning on the network. Without a common start node, each path is a

Dangler path

Which of the following will correctly calculate the total slack in an activity?

Either LS-ES or LF-EF

A merge activity is one that merges with other activities into a succeeding activity.

False

If the project has a duration of 13 days, the project should be completed 13 days from the day it starts.

False

Negative slack can be estimated.

False

The WBS identifies dependencies, the sequencing of activities, and the timing of activities

False

The backward pass determines project duration.

False

The critical path is the shortest path through a network and indicates activities that cannot be delayed without delaying the project

False

The forward pass through a project network determines the critical path

False

When completing a forward pass, you carry the early finish to the next activity where it becomes its early start unless the next succeeding activity is a merge activity. In this case, you select the smallest early finish number of all its immediate predecessor activities.

False

Within an Activity-on-node network, the arrows depict activities to be accomplished.

False

The requirement for a freshly poured foundation to cure before beginning construction is an example of which of the following type of lag?

Finish to Start

The assumption that all immediate preceding activities must be 100% complete is too restrictive in some situations. When an activity is broken down into smaller segments in order to start the succeeding activity sooner, this is called...

System documentation cannot end until three days after testing has started. This is an example of which kind of lag?

Start to Finish

__________ activities are to be completed immediately following a particular activity.

Successor

Which of the following is true about hammock activities?

They are used to identify the use of fixed resources or costs over a segment of a project.

The amount of delay within a task that will not delay the overall project is known as a

Total slack

The amount of time an activity can be delayed and yet not delay the project is termed...

Total slack

Tom is responsible for ordering hardware for a custom home his company is building. The contractor installing the hardware is scheduled to start in 5 working days, but the hardware is on backorder and will not arrive for another 9 working days. Fortunately, Tom has 10 days of slack; however, he shares this slack with the hardware installer. He will have to let the contactor know that the hardware will be ready 4 days later than expected and that the slack for the installer has been reduced by 4 days. Tom and the installer share 10 days of A. Free Slack. B. Shared Slack. C. Total Slack. D. Critical Slack. E. Functional Slack.

Total slack

An activity cannot begin until ALL preceding connected activities have been completed

True

Burst activities have more than one activity immediately following them (more than one dependency arrow flowing from them).

True

Different activities along the same path can have different total slack

True

Even though a project costs time and money to develop, it is worth the effort.

True

Experience suggests that when there are multiple starts, a common start node should be used to indicate a clear project beginning on the network. Similarly, a single project end node can be used to indicate a clear ending

True

Lags can be used to constrain the start and finish of an activity.

True

Only activities that occur at the end of a chain of activities can have free slack.

True

Using free slack does not delay any following activities and requires no coordination with managers of other activities.

True

On a project network, the activity times are derived from the...

Work packages

When creating a project network, your primary input will be the

Work packages

One piece of information that the arrows within the Activity-on-node network can convey is

how activities are related

Information to develop a project network is collected from the

work breakdown structure

A _______ activity is one that has more than one activity immediately following it.

Burst

Which of the following correctly calculates the late start for an activity?

LF-DUR
