Network Diagram Development Problem

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.
