With the rise of enterprise architecture, architectural principles have become increasingly important. They satisfy the organisation’s need for a substantive control instrument at a manageable level of abstraction. Nevertheless, it proves difficult to apply these principles in practice: there turns out to be too great a distance between the demand side and the supply side. However, the alternative – blueprints of the desired situation – has proven equally unrealistic: too complex, too expensive and too soon outdated.

Basing ourselves on an analysis of the application of principles in daily practice, we offer a proven approach to (an ideal definition of) principles, how they are formulated and how they are applied in practice. This way, we can bridge process and substance, theory and practice, corporate IT and system development within projects, and business and IT. In other words: architecture that works.
