Participation and goal achievement of multiparty collaborative systems dealing with complex problems: A natural experiment

Multiparty collaborative systems often deal with wicked sustainability challenges. Previous research has emphasized the important role of stakeholder representation and participation in comprehensive sustainability decisions. We report the results of an empirical test of the effect of stakeholder participation on systemic goal achievement and on multiparty dynamics in a natural experiment, using the results obtained through two simulations in which 44 professionals participated. In one of the simulations a 'party exclusion dynamic' evolved. As the two simulations had a similar baseline, the same number of participants distributed in a similar manner among seven stakeholder parties in each simulation, we could test the effect of stakeholder participation on goal achievement and systemic dynamics, using the other simulation as a comparison. Our results show that stakeholder exclusion prevents systemic goal achievement, disrupts collaboration and induces systemic powerlessness.
