PERT Analysis MCQ with answer and solution

Concept

Activity completion event in PERT

Formula

NONE

Step-by-step solution

1. In PERT network diagrams, activities are represented by arrows connecting node events. 2. The starting node of an activity is termed the tail event. 3. The ending node that signifies completion of an activity is called the head event. Answer: B

Explanation

In PERT project management networks, activities represent time-consuming tasks, while events represent instantaneous progress points. The starting point of an activity is termed a tail event, and its end point is termed a head event. Therefore, the completion of an activity is represented by a head event.

Why the other options are wrong

A) Head activity is not a standard PERT term for activity completion. C) Tail activity refers to the activity originating from a tail event. D) Tail event signifies the start of an activity, whereas head event represents its completion.

Shortcut

An activity arrow begins at the Tail Event (start) and points to the Head Event (completion).

Common mistake

Confusing the head event with the tail event or confusing events with activities in network diagrams.
