In this paper we explore the potential advantages derived from adopting a generalized approach to enterprise management software development, and particularly to achieving the additional flexibility required to provide efficient support to certain types of infrastructure assignment (IA) problems. Within the OMG metamodeling framework, we follow a modeling generalization process, leading to the design and conceptual definition of an infrastructure assignment reference metamodel. The modeling

... ess is carried out through three methodological steps. Taking a company using an enterprise metamodel-based management system as the starting point, we first incorporate infrastructure assignment functionality to the system and then add support for the design of the assignment process. Finally, we propose an infrastructure assignment metamodel, intended to be the core of an independent decision support system.
