For the evaluation of the reference architecture building blocks of a digital platform ecosystem are prototypically implemented and evaluated. This is done within the framework of an agile approach. Thus, parallel to the development of the reference architecture, feedback on the technical architecture can be obtained in order to optimally design the reference architecture. For this purpose a close cooperation with the application part tourism of BayernCloud takes place. This increases the usability and acceptance of the overall solution and ensures the relevance of the reference architecture in practice.
