It almost goes without saying (but I’ll say it anyway) that you must know exactly what the words mean in all parts of your business requirements. In running a complex business (and what business isn’t complex these days?!), the meaning of the words can simply never be taken as a ‘given’.
Some IT professionals believe that if they can model the behavior of a business capability (or more likely, some information system to support it), structural components of the know-how will somehow fall into place. That’s naïve and simply wrong. Business can no longer afford such thinking.
A single, unified business vocabulary (fact model) is a prerequisite for creating a scalable, multi-use body of business rules – not to mention good business requirements. It’s what you need to express what you know precisely, consistently, and without ambiguity. Certainly no form of business rule expression or representation, including decision tables, is viable or complete if not based on one. And I pretty certain that’s true for most other forms of business communication about day-to-day business activity too. What am I missing something here?
