53MARIAn TeR HAAR, nOelle AARTS, PIeT VeRHOeVen subject of a case study performed by the Netherlands Institute for Sport and Physical Activity (NISB). Tackling problems and attaining goals requires the exchange and combination of goods, services and expertise. To achieve that, organizations work together in networks. Social problems, however, tend to be complex because they involve different parties with different backgrounds and different interests. Moreover, constant changes in the environment constantly require a response from organizations to safeguard their position. Confronted with changes, organizations are faced with dilemmas. These dilemmas reveal value contrasts that organizations have to deal with and that lead them to constantly reconsider their identity.Dilemmas and decision-making have been selected as the starting point for data collection in the study, the results of which show that, in order to preserve its mission, the NISB is constantly adapting its identity to suit the environment. In other words, a robust working method and a stable mission constantly create a new interactive identity.
