Final answer:
The project scope document should be created during the Analysis phase of the SDLC, as this phase involves clarifying objectives, analyzing requirements, and setting a solid foundation for the project.
Step-by-step explanation:
In the Software Development Life Cycle (SDLC), the project scope document should be prepared during the Analysis phase. This document outlines the goals, deadlines, and the specific requirements of the project. It is essential to have the project scope well defined early in the development process to set clear expectations and guidelines for the entire project team.
The Analysis phase is the stage where project objectives are clarified, potential systems are identified, and their feasibility is evaluated. The project manager, in this case Sarah, gathers business requirements, assesses the needs of users, and translates them into a detailed document that becomes the foundation for subsequent phases of the SDLC.
