This document summarizes key points from two articles about information infrastructures (II). It defines II as shared, open systems consisting of IT capabilities and user communities. II face problems of attracting early users and adapting to diverse demands as they grow. The document proposes using complexity theory and complex adaptive systems (CAS) as a design theory for II to address these problems. CAS principles of creating attractors to boost growth and ensuring adaptability at the "edge of chaos" are presented as ways to tackle the bootstrap and adaptability problems in II. The document concludes with discussion questions about enhancing II adaptability, the role of institutions/power, other relevant theories, and how II can foster innovation.
