The analysis of operating experience of regulated facilities and activities has traditionally been considered as an important source of knowledge for improving the regulatory process. Regulatory bodies are continuously exposed to learning possibilities from multiple sources of experience, such as from the implementation of regulatory functions, regulatory research, and work carried out by international committees and working groups. Taking advantage of all these learning possibilities is beneficial for further enhancing the effectiveness and efficiency of the regulatory process and this publication was developed to assist in this activity. It presents information about existing practices in regulatory bodies for managing regulatory experience and, through a series of experts’ meetings an assessment of that information is presented to identify possible measures that might help regulatory bodies enhance their current practices where necessary.
