UAM Fractal Concept
Another important concept is that each of the perspective's viewpoints can be looked at as a fractal. Similar to the MDA concept where “one person’s PIM is another person’s PSM”, this IT architecture set framework can be applied in many different contexts: the enterprise level can be viewed as the “default”, but it can also be used at the business domain or business line level, the business departmental level, or in any other context desired. This context needs to be kept foremost in one’s mind when developing the architectural viewpoints; otherwise there will be misunderstandings and confusion. This concept is useful for example in defining more detail for a portion of an already defined architecture—a drill-down mechanism that also has the benefit of maintaining traceability, all the way back to business concepts, drivers, and requirements.
