    Blockchain Support for Collaborative Business Processes
    (Informatik Spektrum: Vol. 42, No. 3, 2019) Di Ciccio, Claudio; · Cecconi, Alessio; Dumas, Marlon; Garcia-Bañuelos, Luciano; López-Pintado, Orlenys; Mendling, Qinghua Lu Jan; Ponomarev, Alexander; Tran, An Binh; Weber, Ingo
    Blockchain technology provides basic building blocks to support the execution of collaborative business processes involving mutually untrusted parties in a decentralized environment. Several research proposals have demonstrated the feasibility of designing blockchain-based collaborative business processes using a high-level notation, such as the Business Process Model and Notation (BPMN), and thereon automatically generating the code artifacts required to execute these processes on a blockchain platform. In this paper, we present the conceptual foundations of model-driven approaches for blockchain-based collaborative process execution and we compare two concrete approaches, namely Caterpillar and Lorikeet.

    Mining Resource Assignments and Teamwork Compositions from Process Logs
    (Softwaretechnik-Trends Band 36, Heft 4, 2016) Schönig, Stefan; Cabanillas, Cristina; Di Ciccio, Claudio; Jablonski1, Stefan; Mendling, Jan
    Process mining aims at discovering processes by extracting knowledge from event logs. Such knowledge may refer to different business process perspectives. The organisational perspective deals, among other things, with the assignment of human resources to process activities. Information about the resources that are involved in process activities can be mined from event logs in order to discover resource assignment conditions. This is valuable for process analysis and redesign. Prior process mining approaches in this context present one of the following issues: (i) they are limited to discovering a restricted set of resource assignment conditions; (ii) they are not fully efficient; (iii) the discovered process models are difficult to read due to the high number of assignment conditions included; or (iv) they are limited by the assumption that only one resource is responsible for each process activity and hence, collaborative activities are disregarded. To overcome these issues, we present an integrated process mining framework that provides extensive support for the discovery of resource assignment and teamwork patterns.

    A New Notational Framework for Declarative Process Modeling
    (Softwaretechnik-Trends Band 36, Heft 3, 2016) Hanser, Michael; Di Ciccio, Claudio; Mendling, Jan
    A New Notational Framework for Declarative Process ModelingIn order to capture flexible scenarios, a declarative approach to business process modeling describes constraints that limit a process’ behavior instead of specifying all its allowed enactments. However, current graphical notations for declarative processes are tough to understand, thus hampering a widespread usage of the approach. To overcome this issue, we present a novel notational framework for representing declarative processes, devised in compliance with well-known notation design principles.
