Study Notes

Activity Predecessors

The immediate predecessor activity for activity E is not specified.
The predecessor activity for activity C is not specified.

Project Network

The activity with no predecessor and the first activity in the project network is not specified.

Activity Relationships

The predecessor activity for activity G is not specified.
Activities joined by node 6 in the project network diagram are not specified.

Critical Path Method (CPM)

The purpose of CPM is not specified.
The critical path in a project network is defined as the sequence of activities that determines the minimum duration required to complete the project.
Critical activities in a project are significant because they determine the minimum project duration.

Project Completion

The completion time of a project includes the duration of the critical path.

Project Network Components

A continuous sequence consisting of nodes and activities in a project network is called a path.

Critical Activities

It is important for a project manager to pay special attention to critical activities because they determine the minimum project duration.

Time Estimates

CPM assumes that the time estimates for each activity are fixed and known.

Non-Critical Activities

A non-critical activity may be delayed without delaying the whole project if its delay does not affect the critical path.

Dummy Activities

A dummy activity is used to maintain the logical relationships between activities in project networks.

Network Diagram

In a network diagram for a project, a path refers to a sequence of nodes and activities.
