Which document is crucial for identifying roles within a project?

The Responsibility Assignment Matrix (RAM) is essential for identifying roles within a project because it visually maps responsibilities and tasks to specific team members or roles. The RAM provides clarity on who is responsible for what within the project, ensuring that everyone understands their contributions and accountabilities. This matrix typically aligns tasks with team members and may indicate levels of involvement, facilitating effective communication and coordination among team members.

The other documents listed serve different purposes. The Communication Management Plan outlines how information will be disseminated and communicates to stakeholders, focusing on information flow rather than individual roles. The Resource Management Plan details how project resources will be acquired and managed but does not specify individual responsibilities or roles. The Project Scope Statement defines the boundaries and deliverables of the project but does not explicitly address individual roles within the team. Therefore, the RAM stands out as the most direct tool for identifying roles in a project context.
