  We discuss questions about user centric development of business process
modeling notations. In the center of our research there is a fully featured
multi-enterprise business process platform (ME-BPP) based on the concepts of
agent-based business processes, which builds on the formal foundations of the
subject-oriented business process management methodology (S-BPM). The platform
is implemented based on cloud technology using commercial services.
Additionally we developed a "block modeling" technique to find a semantically
transparent modeling notation which can be used by novice users to model
subject-oriented business process (S-BPM) models. As this is ongoing research
there are still serious open questions. But, the presented approach breaks with
some of the rules of typical process modeling notations and hopefully
stimulates innovation. Additionally we want to continue our research towards
the enhancement of our modeling approach towards a user centric "syntax and
semantic free" modeling technique to develop user and domain specific modeling
notations.
