Climate Change (term used by David West at Code Freeze 2013)Characteristics of ULS systems arise because of their scale.• Decentralization• Inherently conflicting, unknowable, and diverserequirements• Continuous evolution and deployment• Heterogeneous, inconsistent, and changing elements• Erosion of the people/system boundary• Normal failures• New paradigms for acquisition and policyThese are real.Does Scale Really Matter?: ULS Systems Seven Years LaterLinda Northrop: May 24, 201370© 2013 Carnegie Mellon University
