Decision requirements models allow business analysts, architects, and decision designers to describe the decision-making they need. When these models are combined with business-friendly business rules representations and representations of decision logic such as decision tables, non-technical domain experts can represent critical “know-how” accurately and precisely, resulting in faster time to value and fewer errors. Add in the ability to navigate an existing implementation graphically, and these same users can find out when a change is required and where to make it. The combination of decision requirements models and business rules or executable decision models is a powerful capability.
