Final answer:
The scope baseline is an output of the define scope process.
Step-by-step explanation:
The most accurate statement is 3) The scope baseline is an output of the define scope process.
In project management, the define scope process is the first step in defining the project scope. This process involves creating a detailed description of the project's objectives, deliverables, boundaries, and acceptance criteria.
Once the scope is defined, the create work breakdown structure (WBS) process can follow. The WBS is a hierarchical decomposition of the project scope into smaller, more manageable components.
The scope baseline, which includes the project scope statement, WBS, and WBS dictionary, is developed as an output of the define scope process. This baseline serves as a reference point for managing and controlling the project scope throughout its lifecycle.
