Sequence constraints in business modelling and business process modelling

Separation of concerns is one of the main principles for achieving maintainability and adaptability of software systems. In particular, when analysing business rules it is important to separate business process aspects from essential business rules. Current object-oriented analysis methods offer little support for this. In this paper we explore the problem of sequence constraints on business events. Some of these constraints are the result of the way the business is organised whereas other are essential for the business. In addition we investigate how to ensure the compatibility between business rules and business processes.
