Towards a Taxonomy of Process Flexibility.

E®ective business processes must be able to accommodate changes in the environment in which they operate. Many approaches have been proposed in literature and some of these approaches have been implemented in °exible work°ow management systems. However, a comprehensive classi¯cation of the various approaches has been miss- ing. In this paper, we take a ¯rst step towards a taxonomy of process exibility by distinguishing four types of process °exibility based on an extensive literature study. An evaluation shows that each of the types can be found in contemporary o®erings.
