Defining Business Rules ~ What Are They Really? (Abstract and Table of Contents)
Systems analysts have long been able to describe enterprises in terms of the structure of the data those enterprises use and the organization of the functions they perform, but have tended to neglect the constraints under which the enterprise operates. Frequently these are not articulated until it is time to convert them into program code. While rules which are represented by the structure and functions of an enterprise have been documented to a degree, others have not been articulated as well, if at all.
The GUIDE Business Rules Project was organized in November 1993 to carry out that articulation. This paper, the original report of the GUIDE Business Rules Project (now the Business Rules Group), describes a scheme for understanding the nature of business rules and the categories into which they fall. It presents a formal approach for identifying and articulating the rules that define the structure and control the operation of an enterprise.
