An Analysis of Delegation Mechanism in Workflow Management System

Despite many research works in the features of Workflow Management System (WFMS), several issues are not researched yet. One of them is the delegation mechanism. Delegation mechanism ensures the continuity of processes. This paper presents an analysis of delegation mechanism in a Workflow Management System. Two scenarios in which delegations happen and several delegation rules are shown as the detail of delegation mechanism. Then several problems of delegation are discussed based on the delegations and delegation rules. In order to find out the problems with delegation mechanism, a method is discussed to transform the delegations with delegation rules into a graphic view. With the graphic method, algorithms of finding corresponding delegation problems are presented.
