5 Years of 'Papyrusing' - Migrating Industrial Development from a Proprietary Commercial Tool to Papyrus (Invited Presentation)

Five years ago, Ericsson decided to investigate the possibility of replacing a proprietary commercial UML modeling tool, used at the core of one of its internal toolchains, with an open source alternative based on Papyrus. The motivation for this switch was manifold, including cost, technology integration and community activity. It was clear from the outset that significant effort would be required to make Papyrus into a tool usable in large-scale industrial projects. This journey took time and dedication from both the Ericsson and the Papyrus development teams, but we have now reached the point where deployment has begun. In this paper we provide an experience report from the last five years.
