At the start of the century, the organisational fields belonging to the public employment service and social security, which previously were strictly institutionally separated with their rules and norms, have been brought under one umbrella or network structure in the Netherlands. We discuss how within this structure adaptive and reflexive forms of governance enhance information feedback and simultaneous learning processes both at the top and in the execution level of social security. Based upon document study, interviews and a case study of a sectoral experiment on integral service provision, we illustrate which learning elements occurred in bridging the planning and control cycle of New Public Management at the top with the horizontal mutual adjustment between organisations at decentral level.
