Requirements and constraints

What’s the difference between requirements and constraints? How do we identify and use them in change-projects and in enterprise architectures? This is a query that came up in my web-stats yesterday – and it should (I hope…) be one that I

How do we make EA make sense?

Those notions of ‘whole-enterprise architecture’ that I’ve been describing in the ‘no-plan Plan‘ series of posts make solid sense to a fair few people – particularly those who’ve some experience of systems-thinking, design-thinking and the like. But it’s painfully clear

'Bindedness' in metamodels

A long post-TOGAF conversation on Friday with enterprise architect and academic Erik Proper brought up the question of what I’ve been calling ‘bindedness’ in metamodels and compliance reference models for enterprise architecture. In conventional models and metamodels, links between items
