DICE versus RACI
Clay Parker Jones draws a great distinction.
In Use DICE instead of RACI, Clay Parker Jones contrasts two approaches to responsibility assignment: DICE (decides, informed, consulted, executes) and RACI (responsible, accountable, consulted, informed):
RACI is vague, hard to use, and reinforces the "what the hell is happening here" status quo. DICE is specific, easy to use, and shines a bright light on dysfunction.
