Weighted Alignment Measures of Enterprise Architecture Viewpoints

Enterprise Architecture (EA) allows describing how an organization can achieve its objectives and/or develop innovative strategies, through the creation of a set of engineered models that can be understood by the people associated with the organization. To this end, the set of EA models should be developed as any product in any engineering domain. In general, those models are the artifacts on which we reason to understand the alignment between several viewpoints of the organization. Reasoning on those artefacts in an objective and systematic way requires a shared way to represent them and a set of weighted measures based on this way-of-representing. This paper proposes a framework to analyze and to represent multiple viewpoints of an organization and develops a set of measures to qualify the alignment between those models. These measures are experimented from the alignment of Information System functions with respect to business processes for medical research.
