In the Erasmus+ project EMMA, a concept for a common digital teaching and learning platform is to be developed for an online joint master program. In the initial phase, a status quo survey was carried out among the consortium members, which shows which digital infrastructures are already in use and which functions are considered particularly important by the teachers. This paper shows the first results of the short survey via online questionnaire and discusses the challenges derived from it. Due to the non-homogeneous infrastructure and software use, there are neither the teaching-learning platform nor digital communication applications tools that are used equally by all six European higher education institutions. However, the consortium pursues the idea of specifying a limited tool pool order to strengthen the user experience and usability of teachers and students with different interdisciplinary backgrounds and digitalization expertise.
