    Human activities in distributed BPM
    (Business process, services – computing and intelligent service management, 2009) Takayama, Yoichi; Ghiglione, Ernie; Wilson, Scott; Dalziel, James
    The general concept of inter-workflow system communications has been proposed by the WfMC in 1995. However, there has been little study or use case on general inter-workflow system communications, except for business massage exchange-based protocols. Since BPEL allows a local system to invoke remote BPEL Processes via Web Service interface, this can be used as a mechanism for inter-workflow communications for BPEL Processes. Currently, however, it causes a problem if the remote BPEL Processes use BPEL4Peole extension and include People Activities and Human Tasks. This is because BPEL4People has not anticipated Processes to be called remotely and there is no provision for the remote invocation of the user interfaces. This paper studies a possible mechanism in which a local system can invoke a remote BPEL Process with Human Tasks and let local users perform human activities via user interfaces that are defined in the remote Human Tasks.

    Human Collaborative Workflow and Business Process and Services Computing
    (Business process and services computing – 1st international working conference on business process and services computing – BPSC 2007, 2007) Takayama, Yoichi; Ghiglione, Ernie; Wilson, Scott; Dalziel, James
    Comparing our collaborative human workflow system to existing business process and services computing (BPSC) and workflow models showed that main differences of human workflow are concepts such as human flow, collaborative activity and sub-grouped activity. The possible impact of these findings on the forthcoming implementation of BPSC models that deal with human activities is discussed.
