What best describes a responsibility assignment matrix (RAM)?

A responsibility assignment matrix (RAM) is a tool used in project management to clarify responsibilities associated with specific project activities. It visually represents who is accountable for various tasks and helps ensure that roles and responsibilities are clearly defined among team members. By mapping tasks to individuals or teams, it minimizes confusion and enhances collaboration, ensuring that everyone knows their duties and responsibilities within the project context.

In contrast, identifying project scope limitations pertains more to defining the boundaries of the project and is not the primary function of a RAM. Tracking project expenses during execution focuses on financial monitoring, which does not align with the RAM's role in addressing responsibilities. Outlining project communication strategies involves planning how information will be disseminated among stakeholders, which is also distinct from the RAM's purpose of defining who does what in relation to project activities.
