Indicators of performance are great policy instruments for government because they can change the indicators relatively easily. On the basis of the British case, even constant modification of instruments can be seen as significant, in that this obliges the actors to adapt all the time, ‘running along behind’ instruments that are constantly changing in the name of efficiency and rationality. This instrumental of the instrumentation considerably increases the degree of control by central élites and marginalizes the issue of aims and objectives even further or at the very least, euphemizes them. From this angle, public policy instruments may be seen as revealing the behaviours of actors, with the actors becoming more visible and more predictable through the workings of instruments (an essential factor from the point of view of the state’s élites).
