As an enterprise architecture tool, the MEGA Modeling application can be used to implement a DoDAF project. Many different frameworks have been designed to help implement enterprise architecture projects. Even though common concepts can be retrieved in each framework, vocabularies may differ and sometimes the same words can be used with slight variations. MEGA has its own history and the vocabulary contained in the MEGA Modeling tool metamodel reflects MEGA's vision. The tool also supplies a rich set of diagrams that are dedicated to modeling the different levels of enterprise architecture, however, because of the history, the diagrams are either not named or are not exactly equivalent to those described in the DoDAF V2.0 standard.
