Current workflow management systems (WFMSs) are only applicable in a
reliable and secure manner, if the business process
(BP) to be supported is well-structured. As ad hoc deviations from
preplanned BPs are rather the norm and form a key part of
process flexibility, this limits the applicability of today's workflow
(WF) technology significantly. In this paper we present a
framework for the support of ad hoc structural changes of WFs. Basic
to our approach is a conceptual, graph-based WF model
which has a formal foundation in its syntax and operational semantics.
Based upon this model we have developed a complete and
minimal set of change operations which support users in modifying the
structure of WFs at runtime, while preserving their
correctness and consistency.
