Measuring the coverage of requirements through enterprise architecture models

Engineering of requirements is not supported directly in the metamodels of common Enterprise Architecture Frameworks, such as the NATO Architecture Framework (NAF). This problem has been addressed in a recent study that proposed a ""Requirements View"" as an extension to the NAF metamodel [4]. Based on this we introduce a methodology to determine how well requirements are covered by an architecture model in order to further integrate requirements engineering and architecture modelling and to support a project manager in tracking project progress.
