Competitive markets and the advanced needs of modern societies necessitate mastery and successful design of complex products and systems. The design management of complex products is the focus of this article. We pay particular attention to the fact that organizational communication management is central in the development of complex product design. Any template for complex systems design must pay particular attention to the coupling between product, process, and organization structures. This important coupling can be managed through the effective simulation of the product parametric structure. The complex systems design methodology presented is focused on the organizational structure design, such that the complexity and structure of the to-bedesigned product determines the essential interactions of the designers.
