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.
Enhancing Enterprise Architecture Models with Cost, Quality and Risk Dimensions
Enterprise architecture models are typically rich in structural detail but silent on cost, quality, and risk — the very dimensions that drive executive decision-making. This 2003 presentation by Graham McLeod, delivered at the University of Cape Town, explores how EA models can be extended with these critical dimensions using a knowledge repository approach, enabling architects and business managers to assess current and future scenarios with a fuller picture of the implications of their decisions.
