ABSTRACT
This chapter focuses on the key reasoning, assumptions, components, and methodology for building quality into information processes. It extends the concepts of survivable network systems to the building of robust information chains. The chapter proposes a framework called 'process quality robustness design' (PQRD) as a framework for diagnosing, prescribing, and building quality into information chains. It applies an approach that has been applied in the sphere of network security, the "network system survivability analysis method" to the analysis of the information-supply chain. The chapter reviews the two process management approaches for information supply chains: variation-centered approach and value-improvement approach. The variation-centered approach to process management is typified by Evans and Lindsay's approach to managing information processes. The focus of a value-improvement approach to process management is not on what is done to information, but rather on how information allows its consumers to improve the scope of what they can accomplish.
