RACImátrix

RACImátrix is a project governance tool that expands the traditional RACI matrix by adding a fifth role, M. The acronym stands for the five designations used to assign responsibilities for tasks and deliverables, with RACI forming the core and M providing an additional mechanism for oversight or facilitation. The exact meaning of M can vary by organization, but common interpretations include Mediated, Managed, Monitored, or Moderated.

Structure and roles: In RACImátrix, each task is linked to one or more individuals or roles for five categories: Responsible, Accountable, Consulted, Informed, and M. Responsible denotes those who execute the work; Accountable holds ultimate ownership and final sign-off; Consulted are subject-matter experts who provide input; Informed are kept up to date on progress; M denotes a coordinating or oversight function, such as a mediator, manager, or monitor, depending on the organization’s convention.

Implementation: To implement RACImátrix, define the intended meaning of M clearly in governance guidelines, then populate the matrix with tasks and assign R, A, C, I, and M accordingly. Treat the matrix as a living document, reviewing it during planning, at milestones, and when roles change. Ensure it is accessible, version-controlled, and aligned with project charters and communication plans.

Advantages and considerations: RACImátrix can improve clarity, reduce miscommunication, and strengthen cross-functional coordination by explicitly naming an oversight role. However, the lack of a single standard for M may introduce ambiguity, and this variant requires careful documentation and ongoing maintenance to avoid overlap with other governance tools.

Usage note: RACImátrix is not a universally standardized framework; some teams prefer standard RACI or other variants. When adopting it, organizations should publish the exact interpretation of M and integrate it with existing project management practices.
