Recent scholarship on advisory systems has focussed on the externalization of advisory capacities and sectoral dynamics of change, whereas changes of internal policy advisory systems have not yet been approached systematically. This article proposes an analytical concept for exploring change dynamics in internal policy advisory systems by means of three logics for assessing policy advice (political salience, credibility and representativeness). The approach is illustrated by analysing changes within the internal policy advisory system of the German federal government (1990–2015). The analysis relies on three original datasets on ministerial departments, research agencies and governmental advisory bodies. We find that the internal advisory system of the German federal government is characterized by a differentiated hybridization of advisory logics, which has changed the nature of policy advice.
