A persistent problem in the use of automated workflow management systems for inter-organizational workflows has been the need for manual redefinition of coordination points in the process models when either organization changes its processes. Coordinating communications between production-chain organizations are usually based on the notification of completion of tasks by one party which constitute pre-conditions for activity in another organization; autonomous task changes disrupt coordination. This paper describes a workflow re-coordination model and corresponding expert support system based on workflow goals which are more stable than the low-level machine, role and technique dependent activities which implement them. Following development of the model, we describe a set of three elementary disruption cases which span a large number of common workflow changes. Using these cases we demonstrate that common coordination disruption situations can be totally or partially repaired by use ...
