|---|---|---|---|
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. | When a controversial topic needs depth and discipline at the same time, Fishbowl Discussion makes the structure of the conversation transparent. The format keeps the core small enough for real dialogue and open enough for controlled turnover. | 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. |
