|---|---|---|---|---|
Purposedifferent | A Strategy Map translates strategy into a few connected objectives across perspectives such as finance, customers, processes, and learning. This makes visible which capabilities and activities are meant to drive which results. | 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 cross-functional decisions, responsibilities quickly blur between approval, influence, and execution. DACI arranges these roles so decision pressure, contribution, and information stay cleanly separated. | 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. |
