Abstract

The engineering of enterprise software systems suffers from an inherent lack of creativity and innovation, and are often left to user-centric incremental changes that are simply not disruptive enough for business needs. A design-driven approach to systems creates opportunities for transformative evolution of such systems that are both immediate and futuristic in their impact. Software systems stability can be maintained and monitored during evolution utilizing architectural-level, program-level and information-level stability metrics. Despite increasing complexities involved in the design, development and testing of such large-scale software systems, they are often predicated by simple techniques for decomposition, generalization and specification. However, as always they are much more difficult to merge back together in order to rationalize the entire architecture for the levels of confidence necessary during testing, deployment and commissioning of these systems. mDSM, an extension to Design Structure Matrix approach to software systems design and testing, is a methodology developed to address design-driven rationalization of such complex software system architectures.
