Design RACI Matrix
Map every significant activity in a process or project to exactly one Responsible party, one Accountable party, and explicitly defined Consulted and Informed parties — rather than leaving task ownership implicit and assumed, where multiple people each assume someone else is handling it.
Why This Is Best Practice
Adopted by: The Project Management Institute's PMBOK Guide documents the responsibility assignment matrix (RACI) as a standard project management practice for clarifying roles across complex, multi-stakeholder activities, and RACI matrices are widely used across consulting, technology, and operations functions specifically for cross-functional processes where ownership would otherwise be ambiguous.
Processes and projects without explicit role clarity are documented to experience the "bystander effect" at an organizational level — when responsibility for an activity is diffuse or assumed rather than explicitly assigned, multiple people each assume someone else is handling it, and the activity can go undone entirely, a failure mode explicit RACI assignment specifically prevents by ensuring exactly one person is Accountable for any given outcome.
Leaving task ownership implicit works only as long as informal assumptions about who's responsible happen to align — as soon as they diverge (a new team member unaware of the informal norm, a cross-functional process spanning multiple departments' unstated assumptions), gaps emerge with no clear owner to catch them; an explicit RACI assignment removes this reliance on aligned informal assumption entirely.
