Question

The artificial activity which indicates that an activity following it cannot be started unless the preceding activity is complete, is known as

• A. free float
• B. dummy activity
• C. slack activity
• D. negative activity

Hint:

Dummy activities help establish the order of dependencies in project scheduling, without affecting the overall project duration.

Answer 1

The Correct Option is B

• A dummy activity is a fictitious activity used in project scheduling (PERT or CPM) to indicate dependency relationships between real activities.
• It is not assigned any time or resources, but it is used to show that a specific activity cannot start until another is completed.
• Dummy activities are used to complete the network and establish the correct sequence of tasks, even if there is no actual work involved in the activity.
