The structure of organizations impact their performances. Here, we present a framework based on enterprise architecture to analyze the impact organization structure has on flexibility and coordination within an organization. The framework incorporates organization structure theories by Henry Mintzberg using the Object Constraint Language (OCL) and the Unified Modeling Language (UML) in the modeling tool Enterprise Architecture Analysis Tool (EAAT). The framework has also been applied on a case study where the suitability of three organizations' structures with regards to flexibility and coordination are analyzed.
