An Index to Measure Risk Correlationships
5.1 Introduction
Chapter 4 described a way to structure the risk management problem space in engineering enterprise systems from a capability portfolio perspective. A representation of this space by a supplier–provider metaphor in the form of a mathematical graph was developed. This graph is a logical topology of nodes that depict supplier–provider relationships unique to a capability portfolio. Capturing dependencies between nodes is a critical aspect in the analysis and management of risk in engineering enterprise systems.
In this book, we posit two types of dependencies that affect risk in engineering capabilities for an enterprise system. One is risk inheritance; that is, how risk-dependent ...
