Abstract

This paper outlines experiences with using economic criteria to make architecture design decisions. It briefly describes the CBAM (Cost Benefit Analysis Method) framework applied to estimate the value of architectural strategies in a NASA project, the ECS. This paper describes the practical difficulties and experiences in applying the method to a large realworld system. It concludes with some lessons learned from the experience.
