|---|---|---|---|---|
Purposedifferent | arc42 structures architecture knowledge so teams can document system, decisions, and risks consistently. The template builds a living understanding of the architecture instead of scattered notes. | 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. | The Architecture Communication Canvas plans architecture communication so the right people receive the right message. The method turns technical complexity into deliberate communication design. | Views and Beyond organizes architecture into several views so no single diagram has to do everything at once. This makes it possible to choose the representation that fits the stakeholder's question. |
