Software has become ubiquitous and influences our society in all aspects of our lives. The time of developing software for well known and a limited category of users is long gone. Developer collaboration, too, takes place within software ecosystems that leverage open innovation in large scale, multi stakeholder and multi-team and multi-organization projects and for a wide range of end-users. As designers, we have not only the responsibility but an unprecedented opportunity to develop such complex software for, and with diverse end-users. Notwithstanding the diversity crisis in software development, inclusive approaches to software development offer the promise for more inclusive software. In this talk I will foster a discussion of the relationship between the developers together with their interaction and development processes, and the software they develop, as software products reflect the diversity of understanding and experiences of the developing teams. I argue that our focus should be on the inclusiveness in software collaborations, and describe what design approaches, tools and education environments can support diverse collaborating teams becoming more inclusive in order to develop more inclusive software.
