A key assumption underlying project networks is: ________.
A) dummy activities take up no time
B) the critical path is known with certainty
C) an activity begins only after all predecessors are completed
D) a project network is cyclic

Question

Quizplus · Accepted Answer

The fundamental concept of project networks is that an activity must start only after its predecessors have been completed. This is known as the precedence relationship, and it forms the basis of project scheduling and sequencing. Option A is incorrect because dummy activities are included in project networks to represent logical relationships between activities and to help in determining the critical path. Option B is incorrect because the critical path is the longest path in the project network and may change as the project progresses. Option D is incorrect because project networks are acyclic, meaning they have no cycles or loops.
