Q

Activity-on-Arrow (AOA)

A

Represents the task, or activity, and the node signifies an event marker that suggests the completion of one activity and the potential to start another.

Q

Activity-on-node (AON)

A

The node represents an activity, and the path arrows demonstrate the logical sequencing from node to node through the network.

Q

Critical path

A

The path through the project network with the longest duration. These are identified as having zero float in the project.

16
Q

Float (also called slack)

A

The amount of time an activity may be delayed from its early start without delaying the finish of the project.

17
Q

Forward pass

A

Network calculations that determine the earliest start/earliest finish time for an activity.

18
Q

Hammock activities

A

Summaries for some subsets of the activities identified in the overall project network.

19
Q

Laddering

A

A technique that allows us to redraw the activity network to more closely sequence project subtasks, so the overall network sequence becomes more efficient.

20
Q

Late start (LS) date

A

The latest possible date that an activity may begin without delaying a specified milestone

21
Q

Linked activities

A

Illustrates the scheduling goal.

22
Q

Merge activity

A

Activity with two or more immediate predecessors (tasks flowing into it)

23
Q

Network diagram

A

Schematic display of the project’s sequential activities and the logical relationships between them.

24
Q

Node

A

A junction point joined to some or all of the others by dependency lines.

25
Q

Path

A

A sequence of activities defines by the project network logic

26
Q

Predecessors

A

Those activities that must be completed prior to initiation of later activity in the network

27
Q

Program Evaluation and Review Technique (PERT)

A

An event and probability-based network analysis system generally used in projects where activities and their durations are difficult to define.

28
Q

Project network diagram (PND)

A

A schematic display of the logical relationships of project activities.

29
Q

Project scheduling

A

An output of a schedule model that presents linked activities with planned dates

30
Q

Resource-limited schedule

A

A project schedule whose start and finish dates reflect expected resource availability

31
Q

Scope

A

The work content and products of a project or components of a project

32
Q

Serial activities

A

Are those that flow from one to the next, in sequence.

33
Q

Slack (also called float)

A

The amount of time an activity can be delayed and still not slow the overall project.

34
Q

Successors

A

Activities that cannot be started until previous activities have been completed

35
Q

Tasks (see activities)

A

Must either precede or follow other tasks from the beginning of the project to its completion.

36
Q

Variance (activity and project)

A
37
Q

Work Breakdown Structure (WBS)

A
38
Q

Work package
