| Criterion |  Architecture C4 Model |  Growth Golden Circle |  Architecture Architecture Decision Record |  Architecture Request for Comments |
|---|---|---|---|---|
Purposedifferent | The C4 Model makes a system legible across several resolution levels, from context down to code. It suits situations where different audiences need to understand the same architecture from different altitudes. | In positioning and communication, what an offering actually stands for often becomes blurred. The Golden Circle sharpens a product's inner rationale and connects purpose, approach, and offering into a clear statement. | An ADR permanently records an architecture decision with context, trade-offs, and consequence. It creates continuity for later changes because the decision path stays traceable. | 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. |
