Good decision support requires good information. A key aspect of good information is that it is credible. Presently, architecture frameworks and methods within systems engineering often lacks support for mediating the credibility of the analyses made. This paper presents a method for enterprise architecture analyses that employs an evidential reasoning algorithm for multi‐attribute decision analysis. By doing this, the quality of the analyses as decision support is demonstrated. The method includes an assessment framework, based on established theories, for evaluating architecture scenarios functional and non‐functional qualities. The paper also presents a full scale case study where method has been employed at a large European power company.
