DoD Architecture Framework (DoDAF) Purpose DoD Architecture Framework An architecture framework is a tool It should describe a method for designing an information system in terms of a set of building blocks and for showing how the building blocks fit together. It should contain a set of tools and provide a common vocabulary. It should also include a list of recommended standards and compliant products that can be used to implement the building blocks.
