PK0-004 · Question #273
Which of the following is an advantage of using GERT?
The correct answer is D. Multiple outcome options can be shown. GERT (Graphical Evaluation and Review Technique) is a network diagramming method that supports probabilistic branching and looping, allowing multiple possible outcomes to be modeled.

Why each option
GERT (Graphical Evaluation and Review Technique) is a network diagramming method that supports probabilistic branching and looping, allowing multiple possible outcomes to be modeled.
Discretionary dependencies are a classification of dependency type used across scheduling methods and are not a specific advantage of GERT.
Dummy activities are a feature of ADM (Arrow Diagramming Method), not a distinguishing advantage of GERT.
Slack (float) time is most clearly represented using CPM (Critical Path Method) network diagrams, not GERT.
GERT's primary advantage over other scheduling techniques like PERT and CPM is its ability to model conditional and probabilistic branching - meaning a task can have multiple possible outcomes or paths, and the network can loop back. This makes it suitable for research and development projects where outcomes are uncertain.
