A carpenter is constructing interior partition walls. The project manager indicates that the framing must be completed before the electrical rough-in can begin, and the electrical rough-in must be finished before insulation and drywall. This sequence is an example of what type of dependency?

Question: A carpenter is constructing interior partition walls. The project manager indicates that the framing must be completed before the electrical rough-in can begin, and the electrical rough-in must be finished before insulation and drywall. This sequence is an example of what type of dependency?

Answer options:

• Critical Path dependency
• Discretionary dependency ✅ Mandatory dependency
• External dependency

Correct answer: Mandatory dependency

Explanation: This describes a mandatory dependency, which is inherent in the nature of the work where one task cannot start until another is completed (e.g., framing before electrical rough-in). Discretionary dependencies are defined by the project team, critical path is a sequencing method, and external dependencies involve outside stakeholders.
