16 No APIs without Business Alignment Define your API landscape with respect to Business Capabilities and End-to-End Processes Aligning API Design with Key Business Goals Which assets will be made available? How should the API make those assets available? What kind of applications could be built against the API? How can developers be motivated to use the API? How will the applications create value for the business? OPITZ CONSULTING 2017 Modernize Your IT Landscape with API-Driven Architectures Seite 16

17 No APIs without an API-First Design approach How will consumers use the API? Business APIs need to be easily understandable and appropriate for the respective use case, e.g. don t use SOAP interfaces for Mobile API Design rules allow the creation of consistent APIs, which improves Developer Experience (DX) and results Build early, lightweight prototypes to verify your API Design assumptions can be validated based on the target persona Changes can be made easily, because the API is not bound to real data Short Feedback cycles From App Developers to API Designers From API Owners to App Developers OPITZ CONSULTING 2017 Modernize Your IT Landscape with API-Driven Architectures Seite 17
