Wardley Maps offer a powerful way to analyse a business's competitive landscape, value chain, and the evolution of its components — but most Enterprise Architecture frameworks have not formally incorporated them. This paper examines how Wardley Mapping complements EA methods, proposes a meta model integration using the Inspired Holistic Architecture Language (HAL), and demonstrates practical benefits including reduced effort, improved model fidelity, and richer strategic insight. A useful read for enterprise architects and business architects looking to bring greater contextual awareness into their architecture practice.
The Power of Principles
Well-crafted architecture principles guide thousands of decisions across an enterprise for years — yet typically cost less than 1% of total change effort to define. This presentation by Graham McLeod explores what makes a good EA principle, how to engage stakeholders in defining them, and how principles bridge the gap between strategic intent and concrete design. Drawn from real implementations in banking, assurance, and telecommunications, it includes worked examples and a compliance monitoring approach.
The Central Role of Business Analysis in Enterprise Architecture
Business analysis and enterprise architecture overlap far more than most organisations recognise — in scope, in skills, and in the work itself. This 2007 presentation by Graham McLeod, delivered to the IIBA Western Cape Chapter, makes the case that business analysts are not just contributors to EA but play a central role in shaping business architecture, defining requirements, and bridging strategy with delivery. It covers business and process architecture, requirements traceability, and the career growth path from business analysis into enterprise architecture.
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.
