|---|---|---|---|
Purposedifferent | When a usage scenario needs to become understandable early, it condenses situations, context, and flow into a legible sequence. It helps check concept ideas before anything gets built. | An RFC clarifies architecture context, options, and consequences. It structures technical context, alternatives, tradeoffs, open questions, and review feedback, and captures the result as an RFC document, reviewer comments, and a decision rationale. | In cross-functional decisions, responsibilities quickly blur between approval, influence, and execution. DACI arranges these roles so decision pressure, contribution, and information stay cleanly separated. |
