This document provides a consolidation of the 5G-VINNI business layer requirements and the identification of the associated capabilities leading to the design of a conceptual system supporting business enablement. By following a comprehensive methodology for the definition of the business layer requirements based on the design-thinking approach, the following capabilities were identified as key for any such system to support meaningful system interactions: (i) User Login; (ii) Service Order Management and (iii) Knowledge Repository Management. Each of these capabilities includes a number of sub-capabilities, which are necessary for automated service ordering, provisioning and monitoring, as well as, trust build up. Ref.
