Resumo: This dissertation addresses the collaborative modelling of organisational processes, a topic that has gained growing relevance in the fields of BPM and Information Systems. The elevated level of difficulty associated with the modelling of organisational processes is recognised and addressed. If on the one hand process complexity is inherently high, the greater difficulty emerges from the fact that processes are executed by people, which are subject to partial, fragmented and personal views. Regardless of the efforts made by analysts to act as integrators of operator perspectives, it is invariably difficult to achieve a clear and precise knowledge about the process, as different perspectives are often conflicting and lack the situated knowledge that emerges from conducting daily work routine, particularly with processes where the occurrence of exceptions is frequent. This research was conducted along three major iterations in accordance with the Design Science methodology for Information Systems research. The first iteration produced two artefacts that are central contributions of this research: 1) An innovative process model based on storytelling, a theory for the collective retention of organisational knowledge. The main element of this model is the concept of Scene, which defines a specific organisational context involving actors, a location, a specific situation and a set of organisational artefacts. Each scene is enriched with dialogue, narrative content, and a graphical, storyboard-like representation. A story is built describing a set of scenes in sequence portraying the target process. 2) A modelling tool that consubstantiates and applies the proposed process model. The tool is especially designed to be used by domain experts to the detriment of analysts or modelling experts. The fundamental goal is to reduce the “reality-divide” between prescribed (sanctioned) procedure and de facto procedures in use in the organisation. The second iteration introduces refinements to the model and modelling tool with the purpose of improving the tool’s ease of use, and to support the modelling of the most common workflow patterns in use in order to retain the necessary semantics for integration with workflow engines (for process enactment). The third and last iteration introduces additional refinements to the model and tool in order to foster the creation of richer stories that retain organisational context and current practices. Research artefacts were evaluated through field testing and two independent case studies. The obtained results revealed that 1) process stakeholders are capable of eliciting work processes without the participation of expert modellers; 2) recorded stores reveal an overall high level of detail, retain organizational context (particularly in stories portraying specific scenarios), and can be translated to standard workflowbased process models; 3) recorded stories have contributed to an increased understanding of the target process, and exerted or revealed significant influence over adopted organisational practice.
