Interaction Flow Modeling Language

Foreword

A decade and a half ago, on the strength of a relatively new modeling language standard and a notion that software development needed to be more abstract, the Object Management Group (OMG) took a leap of faith and launched an effort known as the Model Driven Architecture (MDA). The idea was simple: like other, better-established engineering disciplines, software development should begin with abstract models, models that could be organized, evaluated, tested & shared before the targeted system was built. After all, it’s much easier (and less expensive) to change a system when it’s in a high-level (but precise) language, than to change it after it has been fully built (or worse, fielded with customers and users).
