This article looks at the issues currently confronting enterprise architects and the challenges posed when extending EA to be the architecture of the enterprise rather than just its information technology. It describes the contribution that Systems Practice and other disciplines can make to Enterprise Architecture (EA), and considers how the Cynefin sense-making framework can be used to help indicate which are the most appropriate types of approach.
