A Framework for Model-driven Execution of Collaboration Structures

My work on a framwork for model-driven (i.e., hADL driven) execution of collaboration structures was accepted as a full paper at CAiSE 2016.

Mayr-Dorn C., Dustdar S. (2016) A Framework for Model-driven Execution of Collaboration Structures, In Proceedings of the 28th International Conference on Advanced Information Systems Engineering (CAiSE), June, Ljubljana, Slovenia, Springer, (forthcoming, preprint) – [Supporting Online Material]

Abstract: Human interaction-intensive process environments need collaboration support beyond traditional BPM approaches. Process primitives are ill suited to model and execute collaborations for shared artifact editing, chatting, or voting. To this end, this paper introduces a framework for specifying and executing such collaboration structures. The framework explicitly supports the required human autonomy in shaping the collaboration structure. We demonstrate the application of our framework to an exemplary collaboration-intensive hiring process.

Transforming Collaboration Structures into Deployable Informal Processes

Timur and my work got accepted as a full paper at the ICWE 2015 conference.

Abstract: Traditional workflow and activity-centric coordination offers limited process support to human collaborators when unanticipated situations
predominate. Under such circumstances, informal processes focus on
provisioning relevant resources for achieving collaboration goals. Resources include interaction mechanisms such as shared artifact, social networks, and publish/subscribe information dissemination as complex situations typically demand the close collaboration among multiple human process participants.
Currently, however, there exists a gap between (i) selecting and configuring suitable interaction mechanisms (collaboration level) and (ii) deploying the respective collaboration platforms (IT level).
In this paper, we present an approach and techniques for transforming collaboration structures into automatically deployable informal processes. We demonstrate how our tools support the specification of desirable collaboration capabilities subsequently deployed to multiple MediaWiki instances.

Dagstuhl Seminar on Normative Multi Agent Systems (NorMAS 2015)

End of March I had the pleasure to attend my first Dagstuhl seminar. I quite enjoyed the week of inspiring discussions and talks. Many ideas to follow-up in the next weeks and months to come. My connection and approach to NorMAS is outlined in the following position paper:

Position Paper and Talk Title: Collaboration Pattern Modeling in Support of Norm Specification, Monitoring, and Preservation

Abstract: Collaboration-intensive environments call for technical systems that permit flexible user interactions. Rigid workflows are no suitable collaboration paradigm. As users apply various patterns such as shared artifact, social networks, client/principal, or publish/subscribe for interaction, their cooperative behavior becomes largely determined by norms. In this paper, we make the case for explicit modeling of collaboration patterns as the substrate for specifying, monitoring, and preserving norms. Describing collaboration patterns in the form of human-centric component and connector architecture views provides a means for reasoning on collaboration control, flexibility, and ultimately adaptability. We report on recent work targeting executable collaboration patterns and outline resulting synergies with norms.

Specifying Flexible Human Behavior in Interaction-Intensive Process Environments

Dorn, C., Osterweil, L.J., Dustdar, S., (2014) Specifying Flexible Human Behavior in Interaction-Intensive Process Environments, In Proceedings of the 12th International Conference on Business Process Management (BPM 2014), Sep 2014, Eindhoven, Springer LNCS

Abstract: Fast changing business environments characterized by unpredictable
variations call for flexible process-aware systems. The BPM community addressed this challenge through various approaches but little focus has been on how to specify (respectively constrain) flexible human involvement: how human pro-cess participants may collaborate on a task, how they may obtain a joint decision that drives the process, or how they may communicate out-of-band for clarifying task-vital information. Experience has shown that pure process languages are not necessarily the most appropriate technique for specifying such flexible behavior. Hence selecting appropriate modeling languages and strategies needs thorough investigation. To this end, this paper juxtaposes the capabilities of representa-tive human-centric specification languages hADL and Little-JIL and demonstrate their joint applicability for modeling interaction-intensive processes
