Business Process Model &
Notation
Formalized Process
Description
a general integrated approach to
process specification and design
/ run time verification.
Process Specification
Techniques
But what we found missing is
…
Design time
• E.g. Simulink Design Verifier
• Temporal logics / patterns
• Life sequence charts
• UML communication diagrams
Run time
• Run time verification /
monitoring
• Temporal logics

2014/09/30 Georg Hackenberg - Formal Technical Process Specification and Verification 25
Obervation interface allows to…
• Decouple and integrate process
and system specification
• Model process specification over
abstract observation streams
• Model system specification using
observer components
Verification technique allows
to…
• Prove process satisfaction both at
design and at run time
Improve graphical notation of
the process specification
• Reduce modeling effort through
inclusion of specification patterns
Analyze and improve scalability
of the presented approach
• Prove process satisfaction for the
entire pick and place unit
• Prove process satisfaction step-
wise from activity to activity?
