What is a dummy activity in project scheduling?

• A. An activity that has no resources assigned
• B. An activity that has a duration of zero
• C. A placeholder that shows a dependency between two activities
• D. An activity that is completed in advance of others

Answer: (C)

A dummy activity is used in project scheduling to represent a logical relationship or dependency between two activities without requiring any resources or time allocation. Specifically, it serves as a placeholder to illustrate how one task must proceed in relation to another, thereby clarifying the sequence of activities within the project. This is particularly useful in complex projects where multiple dependencies exist, and it helps to maintain a clear and accurate project schedule without adding actual work or duration. While it is true that a dummy activity does not consume resources or time, its primary purpose is to express the necessary relationship between two other activities. Therefore, understanding the context and function of a dummy activity emphasizes its role in ensuring that project schedules accurately reflect the workflow and dependencies among various tasks. This aids in proper project planning and execution, allowing for better visualization of the project structure and progress.
