The present invention extends to methods, systems, and computer program products for determining capability interdependency and analyzing risks in business architectures. Accordingly, embodiments of the invention can be used to drive an understanding of the relative interdependency (complexity) of a capability and how capabilities impact one another. Connectedness and/or data exchanged between capabilities can be used to formulate relative interdependency (complexity) of a capability and can be analyzed to inform a number of strategies from data architecture and business intelligence and project risk. Other risk/impact analysis data can be combined with interdependency (complexity) to present risk/impact analysis scenarios for organizations.
