Scalability in modeling has many facets, including the ability to build larger models and domain specific languages (DSLs) efficiently. With the aim of tackling some of the most prominent scalability challenges in Model-based Engineering (MBE), the MONDO EU project developed the theoretical foundations and open-source implementation of a platform for scalable modeling and model management. The platform includes facilities for building large DSLs, for splitting large models into sets of smaller interrelated fragments, and enables modelers to construct and refine complex models collaboratively, among other features. This paper reports on the improvements provided by the MONDO technologies in a software development division of IK4-IKERLAN, a Medium-sized Enterprise which in recent years has embraced the MBE paradigm. The evaluation, conducted in the Wind Turbine Control Applications development domain, shows that scalable MBE technologies give new growth opportunities to Small and Medium-sized Enterprises.
