A statute can be clean on the page and still come apart on the way down. Implementation research grew when that gap became hard to treat as a simple administrative afterthought. From the top, the question is how a decision-maker's intent is carried through. From the bottom, Lipsky's street-level officials use discretion, simplify, and routinize in order to survive uncertainty and stress. Korea, a unitary state whose local autonomy came late, felt the difficulty more sharply in the 1990s, when NIMBY and PIMBY disputes among residents made delivery harder to take for granted.
Classic administrative models, in this telling, had simplified the policy process so far that research was slow to move. Implementation stopped looking like a mere last stage once it became clear that a decision and a result can stand far apart. Pressman and Wildavsky's case work is cited for a close bond between design and delivery. McLaughlin's types of interaction — mutual adaptation among them — are mentioned as one way of sorting how implementation actually runs.
Korea enters the story as a unitary state whose local autonomy arrived late. In the 1990s, the spread of NIMBY and PIMBY feeling among local residents made delivery harder, and interest in implementation grew with that difficulty. The country's administrative shape, in other words, did not make the last mile automatic.
A top-down view asks how a decision-maker's intent is carried through, and often assumes a fair amount of knowledge about the capacity and commitment of those who will carry it. Pressman and Wildavsky, in this placement, still belong on that side because they emphasize intent. The limits noted for the approach include passing too lightly over the difficulty of delivery when many actors are involved, and listing so many factors that a priority is hard to see.
A bottom-up view begins in criticism of that picture. Lipsky's street-level officials hold real discretion, and they simplify and routinize the work in order to live with uncertainty and stress. When the two directions are drawn toward each other, Van Meter and Van Horn set out six variables that help explain results, and Sabatier and Mazmanian model how a problem's tractability, a statute's power to structure delivery, and non-legal conditions shape the stages of the process. Compliance and non-compliance are named as types to be studied, at home and abroad. The models are given as this account gives them, not as a new complete map.

Their case study is cited for a prescriptive lesson: design and implementation are tightly bound, and that bond should be emphasized. In this account their work is also placed among top-down studies, because it still gives weight to the decision-maker's intent. The point is not that a law writes itself into the world, but that a design which ignores delivery is already incomplete.
It starts as a critique of top-down delivery. Lipsky is treated as a founder of the approach. Street-level bureaucrats, in his account, exercise considerable discretion; to get through uncertainty and job stress they simplify the work and make it routine. The view from the counter, not only from the statute, becomes part of what implementation is.
Van Meter and Van Horn offer six variables for explaining implementation results: goals and standards, available resources, relations among organizations, the character of the implementing body, the economic, political, and social setting, and the disposition of implementers. Sabatier and Mazmanian model independent influences — how tractable the problem is, how far a statute can structure delivery, and non-legal variables — and the stages of the process that those influences touch. Those models are named as they appear here.
