The architectural maps at solution level are connected to the enterprise-wide maps via unique references (e.g. solution requirements must refer to exactly one business capability). This allows permanent feedback cycles between solution architecture and capability/enterprise architecture.

The enterprise-wide architectural maps are an important input for the scoping of solutions. These permanent feedback-cycles ensure that findings at solution levels that are relevant at enterprise-level are taken to the next level. Thus, the architecture owner at capability level uses the findings of the solution level as an input for the target architecture of his/her capability.

Architectural work is permanently carried out at the detailed solution level and at the capability and enterprise level side by side. Many solution teams create architecture within their scope simultaneously. Whenever they find issues relevant at the capability level, they take them to this higher level, where the architectural owner has to integrate them into the target architectural maps for his capability
