Using information activity and capability effect to bridge gaps between OV, CV and SV/SvcV

To facilitate system architecture development using DoDAF, we propose an architecture development methodology based on DoDAF 2.0 in this paper. First, based on experiences in practice, gaps between Operational Viewpoint (OV), Capability Viewpoint (CV) and System/Service Viewpoint (SV/SvcV) are analyzed. Second, to bridge the gaps, two architecture viewpoints, i.e. Information activity Viewpoint (IaV) and Capability effect Viewpoint (CeV) proposed in our previous work, are introduced. In addition, a meta-model is provided to define key architecture elements and their relationships in these six viewpoints (i.e. OV, CV, IaV, CeV, SV and SvcV). Third, via analysis of element associations in different viewpoints and models, we give a suggested process of developing system architecture using the six viewpoints and their models, including model development steps, inputs and outputs of each step. Finally, a case study is conducted by applying our methodology to describe architecture of a defense system. Results show that our methodology can effectively facilitate system architecture development and help architects (especially for information system architects) to develop architecture from OV, CV to SV and SvcV.
