Business Rules
Business rules become more and more to the forefront of todays international business. New business rule dilemma's evolve when e.g. sourcing (outsourcing, eastsourcing, etc) is an issue within organisations. Business rules are applied in multiple ways. Sometimes literally thousands of rules apply within one organisations. Only recently some best practices and tools became available for this highly complex area.
Recently a business rules manifesto appeared to give direction to this field. You can download this manifesto in different languages here
