The classic development waterfall consists of two sequential stages. There is an ‘architectural synthesis’ stage that creates new architecture, new fundamental structure. This is followed by an ‘engineering design’ stage that develops and optimizes a system to satisfy requirements produced by the first stage. In addition, to having different goals, these two stages employ different tools, different processes, and demand different skills. Synthesis, the creation of new architecture, employs inductive reasoning, insight, and creative problem solving. Synthesis requires holistic solutions consistent with a single unified vision. As a result, the synthesis stage resists partitioning into subtasks. The synthesis of complex architectures stresses the capacity of individual architects and is best executed with Special Expert Teams (SETs). SETs are temporary task-directed teams of experts that benefit from special management tools. SETs have the capacity to conceptualize overarching concepts. This paper presents the concept of SETs for the creation of enterprise architecture.
