Extending FEA and DODAF to Support Cost Modeling

Models and Methods Track



The Federal Enterprise Architecture (FEA) and the Department of Defense Architecture Framework (DoDAF) are widely recognized, applied, and often mandated methods to define future systems and their interplay with current solutions to close capability gaps with fit for purpose solutions.

However, the focus is currently on operational capabilities and the cost aspect is easier done separately or as an afterthought once the ‘optimal technical solution’ is specified. Current research at Old Dominion University in two related domains have the potential to contribute to a paradigm shift in cost modeling based on architectural descriptions.

First, it is possible to extend FEA and DODAF into executable architectures that can be embedded into an operationally validated executable context. This approach allows the technical optimization not only for individual systems and project but can be applied to portfolio management as well, showing how operational decision for or against a system will influence the operational performance of a portfolio mix.

Second, as each architecture specifies functions in detail for the life cycle of a system, and each of this functions can be tagged with associated costs (or even cost-at-time information taking inflation and other constraints into account), the cost of using a system can be specified in more detail in the context of its application. Bringing executable architecture, operational context, and context-specific cost functions together allows to better understand the cost modeling over the life cycle of a system based on portfolio decisions.
