Estimating Practice Exam

Cases of underlap and overlap occur in what context?

1. Design flaws

2. Lack of communication

3. Undefined work scope

4. Material shortages

The correct answer is: Undefined work scope

Underlap and overlap primarily refer to issues related to the boundaries and responsibilities within a project or task, particularly regarding work scope. In the context of project management and estimating, underlap occurs when there are gaps in coverage, meaning that not all necessary tasks or elements are accounted for, leading to potential delays or deficiencies. On the other hand, overlap happens when tasks or areas of responsibility are duplicated, causing confusion, wasted resources, and inefficiencies. When the work scope is undefined, it creates uncertainty about who is responsible for what, resulting in both underlap and overlap. This ambiguity can lead to important elements being overlooked or duplicated efforts within a project. Establishing a clear and defined work scope helps prevent these issues, ensuring that every aspect of the project is appropriately addressed and assigned without confusion or redundancy. Thus, the context of undefined work scope is critical in analyzing scenarios where underlap and overlap occur.
