During the creation of a Work Breakdown Structure, what process is used to break down deliverables?

The correct answer is B, decomposition. In project management, decomposition is a fundamental technique used to break down project deliverables into smaller, more manageable components. This process allows project managers and teams to organize and define the total scope of the project by separating deliverables into individual tasks and subtasks.

By using decomposition, a project manager can clarify the details and requirements of each component, making it easier to estimate resources, time, and budget necessary for each part of the project. Additionally, this process aids in identifying dependencies and facilitating better planning and execution of the project.

In contrast, the other processes mentioned do not specifically address the breakdown of deliverables. Aggregation refers to combining elements, not breaking them down into smaller parts. Collaboration involves working together to achieve a common goal, which is essential in project management but does not pertain directly to the structuring of deliverables. Evaluation focuses on assessing project performance and outcomes rather than the initial breakdown of tasks or deliverables. Thus, decomposition is the correct process used during the creation of a Work Breakdown Structure.
