29 Questions European PSA networks, cooperation forums, programs What is the main benefit of the networks? From which (kind of) networking activities you get most benefit? Do we have too much or too little European networking in PSA area? Is there is a need to consolidate the activities? In which area/questions/activities do you miss networking? European harmonisation in PSA methodologies and risk informed regulation How do you see the present situation in Europe (catastrophic, unsatisfactorily in some issues, well in progress, ideal, )? Is it desirable to aim at harmonisation? Is it realistic to aim at harmonisation? Which actions are needed to achieve better harmonisation? Can any of the present networks provide a forum for harmonisation? Do we need to develop/support common report /databases that we all refer to in regulatory actions? Do we need peer review processes in Europe to secure consistency and quality?
