The RISCOM project is different from the others in that it develops and employs a theoretical model. The overall objective of the project is characterized as supporting “transparency of decision-making processes in the nuclear waste programmes of the participating organizations, and also the European Union, by means of a greater degree of public participation.” RISCOM II had six “Work Packages.” Work Package 1 involved studies of issues raised by performance assessment. Work Package 2 involved an organizational model and a method designed to investigate structural issues affecting transparency. In Work Package 3 a special meeting format was used to promote the development of consensus and a “European approach” to public participation. Work Package 4 involved analysis, and limited experimental testing, of public participation processes. In Work Package 5 a hearing format was developed with particular emphasis on creating non-adversarial situations. Two topical workshops and a final workshop were conducted under Work Package 6.

The RISCOM Model includes the Viable Systems Model (VSM) and a methodology designed to transform basic principles to practical applications. The VSM is an organizational model that includes five interrelated communications loops that are described and analyzed in an effort to improve transparency for interactions between waste management organizations and stakeholders. The methodology employed is called TASCOI (the acronym stands for Transformation, Actors, Suppliers, Customers, Owners, Interveners).
