Question: 1 / 400

According to arrow notation, how does the length of an arrow relate to an activity's duration?

The longer the arrow, the longer the activity's duration

The shorter the arrow, the longer the activity's duration

In the context of arrow notation, commonly used in project management and network diagrams, the length of the arrow is typically intended to represent the logical relationships and dependencies between activities rather than their duration. The accurate interpretation is that the length of the arrow does not correlate directly to the duration of the activity.

While some may mistakenly interpret a shorter arrow as indicative of a longer duration, this is not how arrow notation functions. Each activity's duration is specified elsewhere, such as alongside the activities in a schedule or as part of a project management tool. The key takeaway is that the arrow itself serves to illustrate the sequence and interdependencies of tasks, making duration representation a separate consideration from the arrow's length.

Thus, the length of the arrow remains an abstract representation, helping in visual analysis of the flow of tasks rather than conveying specific duration details.
