  Commercially available business process management systems (BPMS) still
suffer to support organizations to enact their business processes in an
effective and efficient way. Current BPMS, in general, are based on BPMN 2.0
and/or BPEL. It is well known, that these approaches have some restrictions
according modeling and immediate transfer of the model into executable code.
Recently, a method for modeling and execution of business processes, named
subject-oriented business process management (S-BPM), gained attention. This
methodology facilitates modeling of any business process using only five
symbols and allows direct execution based on such models. Further on, this
methodology has a strong theoretical and formal basis realizing distributed
systems; any process is defined as a network of independent and distributed
agents - i.e. instances of subjects - which coordinate work through the
exchange of messages. In this work, we present a framework and a prototype
based on off-the-shelf technologies as a possible realization of the S-BPM
methodology. We can prove and demonstrate the principal architecture concept;
these results should also stimulate a discussion about actual BPMS and its
underlying concepts.
