This paper shows the results of incorporating the MSP (multiple
streams perspective) into the cyberneticbased hazard analyzing
methodology STAMP (systemstheoretic accident modeling and
process) to improve the developmentprocess of policies within
sociotechnical systems. Understanding policy processes is seen
as crucial in improving safetycompliance of policies and thus
increase system’s safety. MSP illustrates several obstructions to
safetycompliant policy making e.g. due to unclear preferences,
time restrictions or manipulation. In contrast the application of
cyberneticbased analyzing methodologies shows significant
improvement in increasing systems’ safety, because it generates
a deeper understanding of hidden processes and feedbackloops
within sociotechnical systems. STAMP models control struc
tures of systems’ resources, showing the cascaded relationships
between interdisciplinary control components, e.g. market
actors and policy entrepreneurs. This paper initially focuses on
the description of sociotechnical systems, MSP and STAMP.
Afterwards it focalizes the analogy between MSP and STAMP
and subsequently generates a hybrid methodology incorporating
MSP into the system’s control structure modeled by STAMP.
Furthermore the explanatory power of STAMPMSP is exem
plified by analyzing the German traffic system.
