Process-Aware Information Systems (PAIS) allow for process changes at different levels. In general, respective changes must be enabled at the process type as well as the process instance level. While the former become necessary to deal with the evolving nature of real-world processes (e.g., to adapt the process to legal changes), the latter are needed to cope with exceptional situations. Vendors often promise flexible solutions for realizing adaptive PAIS, but force users to realize process adaptations at a rather low level of abstraction. Apart from this, several competing paradigms exist, all trying to tackle the need for process flexibility (e.g., adaptive process management vs. case handling).
