Scaling up software architecture analysis

This paper will show how architecture design and analysis techniques rest on a small number of foundational principles. We will show how those principles have been instantiated as a core set of techniques. These techniques, combined together, have resulted in several highly successful architecture analysis and design methods. Finally, we will show how these foundations, and the techniques that instantiate them, can be re-combined for new purposes addressing problems of ever-increasing scale, specifically: addressing the highly complex problems of analyzing software-intensive ecosystems.
