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. | For a search for solutions with many degrees of freedom, a grid emerges for systematic combinations. The method separates features, variants, and exclusion criteria, so the space gets explored deliberately. | For a seemingly familiar problem with paralyzing seriousness, the method dissolves pressure and fear of judgment. It deliberately makes failure pictures extreme, so hidden assumptions become visible faster. This clarifies what a workable path should avoid. | 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. |
