Which document centralizes all requirements information for the purpose of impact analysis?

The requirements traceability matrix is a crucial document in project management that serves to centralize all requirements information, facilitating impact analysis. This matrix links requirements to their origins and keeps track of their status throughout the project lifecycle. By mapping each requirement to its associated project deliverables, stakeholders can easily assess how changes in one area may affect others.

This document is essential for ensuring that all requirements are addressed and that any changes or updates are properly evaluated in terms of their potential impact on the project. It provides a clear and organized view of how each requirement relates to the overall project objectives, making it easier to manage scope and maintain alignment with stakeholder expectations.

In contrast, other documents like the risk register focus on identifying and managing potential risks, the project charter outlines the project's objectives and stakeholders without diving into specific requirements, and the change log tracks changes made during the project rather than centralizing all requirements information.
