Holonic networks constitute a type of organizational structures widely used at manufacturing enterprises. In an educational context, however, this type of structures remains practically unknown. The purpose of this paper is to demonstrate the applicability of these organizational structures to the design of professional training programs. Thus, we have herein proposed a conceptual model for holonic organizations that captures the structure and characteristics of this type of organizations. The use of this model is illustrated through the design of an academic organization devoted to professional training programs on Software Engineering. This paper describes the use of the combination of Holonic Networks and Business Models techniques for modeling complex organizational systems.
