Most organisations attempting enterprise architecture have reached for ad-hoc tools — Word, Excel, Visio — or CASE-derived modelling tools never designed for the job. This 2005 presentation by Graham McLeod sets out a comprehensive framework of requirements for a purpose-built EA management tool, drawing on Zachman, TOGAF, Spewak, and Schekkerman, before presenting the design and architecture of Archi/WebModeler, Inspired's own web-based EA repository solution. It covers everything from meta-modelling and collaboration to inferencing, scenario management, and governance support.
