How do institutions transform? To answer that question, this article introduces a dynamic theoretical framework of gradual institutional changes. Instead of looking at each mode of gradual change—like layering or drift—as a stand-alone process, we examine how the application of one mode of change affects the opportunities of change agents to induce additional modes of gradual transformation. We first point to the fact that any single mode of change produces a real but limited transformation. Nevertheless, since the application of a gradual mode of change alters the institutional context, it opens new change opportunities by affecting the support in the targeted institution and/or its internal coherence. Consequently, change agents who aspire to comprehensive transformation will be able to use these new opportunities to implement additional modes of gradual transformation. Two case studies of gradual social policy transformations in Israel exemplify these theoretical assertions.
