Our cooperation with the Open Models Laboratory for the deelopment of a 4EM modelling toolkit which started in 2017 bears further fruits. Last year's release 2.0 provided a helper function that supports users when creating new relations. Besides improved helper functionality and bgufixes, the new 2.2 release provides a new Product-Service-Model. It allows to model structure and dependencies of products, services, and featrures as well as their integration with the other 4EM sub-models.
Version 2.2 of the 4EM Modelling Toolkit can be obtained for free here.
