要旨:
Public business processes can be very complex. That makes it hard for citizens
to understand these processes and for software companies to implement them into
software tools. Changes of the process entail expensive effort in both teaching
the citizens and adapting the software. For business processes several
model-based approaches have been suggested to deal with high complexity, such
as BPMN. However, modelling simplifies work of software developers rather than
of citizens. We present an approach where an adequate user-interface with
user-centric pertinent information is derived directly from the models. Our
approach combines the advantages of having models for the software developers
with the requirements of the users.
The modelling technique we are using is Event-driven Process Chains (EPCs).
EPCs are widely accepted in the commercial area and are comprehensively
investigated in the academic area as well. Due to their graphical description
they are easy to understand. EPCs are implemented in the ARIS toolset, which
offers the possibility to attach attributes to the elements of the EPCs. This
paper will demonstrate how these attributes are used to derive a
user-interface, e.g. a relevant website or document, for each state or
transition of the EPC. The tools used extract the values of the attributes and
incorporate them into a web-based user-interface according to the EPC of the
modelled business process. Execution of the model then is equivalent to running
the user-interface. A change of the process requires a change of the model
only, which is much easier to handle than changing the implementation of the
user-interface.
