The existing Workflow Management Systems, WfMS (ACTIONTm, Xsoft InConcert, Team Ware) show some insufficient due essentially to two factors. First, the enterprises express a real need of WfMS that deal with flexible business processes. These later must adapt to the optimization of enterprises work methods and the evolution of their needs. Second, the enterprises also need of control mechanisms and modeling tools for their WfMS in order to design robust workflow models assuring an efficient and flexible processing of errors and exceptions of execution. In others words, the WfMS must deal with Workflow mining to support Business Processes Re-engineering (BPR). A BPR is a method to improve the effectiveness and efficiency of business processes. Existing propositions in the literature are rather dedicated to the process perspective mining and they neglect the discovering of organizational perspective although it is decisive for the enhancement of existing workflow or the proposing of a new Workflow. The paper addresses the workflow mining by considering the organizational perspective. By organizational perspective, we mean the organizational structures (Federation, Hierarchical, Market and so on) and interaction protocols (Contract net, Auction...) describing respectively the forms of work and the activities allocation process between actors. This paper defends the idea that organizational dimension in multi-agent system is an appropriate approach to discover this organizational perspective since it (i) provides inter-agents communication languages based on performatives which allow capturing the semantic of exchanges between actors, (ii) it introduces organizational structures to highlight the forms of work and (iii) it offers powerful interactions protocols which permit to identify the dynamic organizational structures. First, this paper proposes a Workflow log meta-model which extends the classical one. Then, it provides some algorithms to permit the discovering of the main organizational structures and interaction protocols. Third, it presents the Management process of Water distribution crisis case study to illustrate our approach. Finally, the paper describes the developed prototype, called DiscopFlow, in order to validate the proposed solution.
