It can also be argued that the evaluation approaches of each of the involved groups are slightly different in focus and emphasis, hence justifying the multiplication of initiatives (Scheerens, 2013). This approach is in line with the Dutch tradition of multi-stakeholder involvement and may be described as “strategic redundancy”. It also echoes elements of a governance system often described as the “Polder model”, where each stakeholder group is given room to play its role, and channels for debate and negotiation are kept open, even in periods of major disagreements.
