This article shows a phase of a project whose main objective is the definition of a frame of reference for anapplication methodology of the Enterprise Actor Model - MADE, using as a similar basis the methodology for MultiagentSystems INGENIAS. MADE consists of entities whose relationships must be represented graphically, in such a waythat facilitates the design and implementation of software.The graphic representations required can be done with an existing graphic language through the definition of models.Five models represented in UML language class diagrams were defined: ADE Model, Task and Objective Model, InteractionModel, Environment Model and Organization Model. These models are a complete and robust representation of thesystem, which facilitates later software implementation
