Why must assumptions be documented during requirement analysis?

Documenting assumptions during requirement analysis is essential because assumptions often relate to conditions or situations that can significantly affect a project. When a true condition changes—such as stakeholder expectations, market dynamics, technology, or resource availability—it can lead to impacts on the project’s requirements or outcomes.

By documenting these assumptions, all stakeholders have a clear understanding of the foundational beliefs that underlie the requirements. This awareness helps in communicating potential implications if those assumptions prove to be incorrect or if they change over time. It fosters transparency in the requirement analysis process and allows for proactive management of impacts and adjustments to the project's goals and deliverables when necessary.

In contrast, while the other choices touch on important aspects of requirement management, they do not directly address the significance of documenting assumptions in relation to their potential impact—preparing the team for changes in the project landscape.
