Approaches to Developing Network
Schedules
What are the three different approaches to developing network schedules? -
CORRECT ANSWER ✔✔✔ Program Evaluation and Review Technique (PERT), Arrow
Diagramming Method (ADM), and Precedence Diagram Method (PDM).
What is a key characteristic of the Arrow Diagramming Method (ADM)? - CORRECT
ANSWER ✔✔✔ ADM uses only a single duration estimate, which is the planned
duration for the activity under normal conditions.
How do PERT and ADM represent activities in network diagrams? - CORRECT
ANSWER ✔✔✔ Both PERT and ADM are 'activity-on-arrow' (AOA) methods, where
activities are shown as lines/arrows between events.
What type of relationship do PERT and ADM treat all activities as? - CORRECT
ANSWER ✔✔✔ They treat all relationships as 'finish-to-start,' meaning activity B
cannot start until activity A is complete.
Why is the use of PERT and ADM limited? - CORRECT ANSWER ✔✔✔ The limited
use of both PERT and ADM is directly related to the increase of computer-based
scheduling tools.
What does the duration estimate in PERT approximate? - CORRECT ANSWER ✔✔✔
The duration estimate in PERT approximates the 'most likely' duration for the
activity.
Is ADM commonly used in modern scheduling? - CORRECT ANSWER ✔✔✔ Similar to
PERT, ADM is seldom used in modern scheduling.
