European Policy Analysis incremental policy change characterized by processes of layering and drift.” These processes of policy layering have in turn been promoted by an era of considerable policy innovations that were brought in by ever-diversifying forms of governance: “With new actors came new ideas, creating a rich mix of policy elements that, in a context of institutional ambiguity, proved hard to gather up into optimal policy designs” (Rayner and Howlett 2009b, 101). According to this interpretation, integrated strategies often represent conscious efforts to combine multiple policy elements in a more coherent way and overcome the disorganized character of the existing policy system (see also May et al. 2005; May, Sapotichne, and Workman 2006). In-depth case studies on the national sustainability strategy in Germany point to less ambitious goals of policymakers. Besides following international obligations, sustainability strategies are perceived by policymakers as opportunities to overcome existing institutional constrictions and gain action capacity within a highly institutionalized and fragmented policy system (Bornemann 2011; 2014; Tils 2005; 2007). There are obviously many different empirical forms of IPS within and across different fields and policy levels (see, e.g., Swanson et al. 2004). However, in various reviews several recurring elements have been identified (Bornemann 2014; Casado-Asensio and Steurer 2014; 2008; Steurer and Martinuzzi 2007). First, at the core of an IPS, there is usually a (set of) programmatic document(s), such as a national sustainability strategy or a climate adaptation strategy, in which problems, goals, and means are defined. Second, these strategies emerge and are enacted in a certain organizational arrangement. Typically, such an arrangement consists of some interdepartmental coordination structure that spans various administrative departments and includes elements that ensure consultations with scientific actors, as well as the broader public. Finally, IPS bear a procedural dimension as both the organizational arrangement and the strategy documents are subject to regular revisions and adaptations over time. Despite these g eneral empirical commonalities regarding the form of IPS, the academic literature has not offered an unambiguous understanding of what IPS are, how they can be distinguished from other forms of policymaking, and how they ought to be analyzed to capture their peculiarities. In fact, there are several conceptual propositions and analytical perspectives on IPS. These are based on various heterogeneous sources, ranging from political agreements and guidelines for practitioners prescribing what administrators can and should do to formulate and implement IPS (DalalClayton and Bass 2002) to empirically informed theoretical reflections (Meadowcroft 2007; Steurer 2007; 2010; Tils 2007). These various perspectives focus on different aspects of politics and are based on diverse presumptions regarding the functions of IPS, as well as the forms they are supposed to take in order to fulfill these functions. Early investigations have examined and analyzed IPS as a new form of policymaking and steering that cuts across various sectors but aims at solving complex policy problems by setting longterm goals and defining measures (Jänicke 2000; Nordbeck 2001; Wurster 2013). Following this policy perspective, IPS are all about defining and solving problems in a comprehensive and rational manner. 171
