The advent of the new economy brought university reforms to the limelight, and higher education research concentrated on the study of interactions of multi-level, multi-actor policy reforms, to the detriment of studying policy implementation. The ebbing of implementation analysis in the mid-1980s has probably put researchers off following up policies to the point of delivery, resulting in what critics dubbed a 'missing link'. Policymakers more pronounced need to evaluate the impact of the policies they adopt, inter alia, has led to a renewed interest in bottom-up implementation in other public policy fields, but not as much in higher education research. The article builds on a Network Governance-informed approach for studying policy reform in higher education and adapts it to study of policy implementation with a focus on transition systems. Witte's actor-centered new institutional framework is taken as a springboard, and some of its underlying assumptions are reviewed for that purpose, adding insights from public administration literature (NPM) and Lipsky's street-level bureaucracy (SLBy). Ultimately, it proposes a politics-institutions framework to account for the institutional change entailed to the reforms.
