To implement such a system, stakeholders must be
identified, characterized and organized, in order to give them
a specific degree of participation, thereby accounting for their
heterogeneity. Participatory techniques must then be chosen
according to the specified degree of participation. The idea is that
stakeholders can be involved to different degrees, using parallel
and varying participatory techniques. Finally, when the entire
process has been completed, an evaluation must be conducted. In
the following sections, each step of this framework will be
described.
