Implementation and Public Policy

Mazmanian and Sabatier developed a framework classifying variables affecting implementation into three categories. Independent variables include: (1) tractability of the problem—technical difficulty, diversity of target behavior, and scope of required change; (2) the statute's ability to structure implementation—clear objectives, valid causal theory, adequate funding, hierarchical integration, and formal access rules; and (3) non-statutory factors—socioeconomic conditions, public support, and leadership skill. Dependent variables include outputs from implementing agencies and ultimate policy outcomes.

Pressman and Wildavsky's 1973 study of Oakland's economic development program portrayed implementation as fraught with delays and complexity, with an emphasis on the difficulty of achieving coordination. Mazmanian and Sabatier published a decade later as a response, arguing that implementation can be systematically structured through careful statutory design. Where Pressman and Wildavsky highlighted the inherent unpredictability of implementation, Mazmanian and Sabatier emphasized the conditions that make success more likely and identifiable .

Statutory structuring refers to the ways legislation can shape the implementation process through specific provisions. The framework identifies six key statutory variables: the accuracy of the objectives hierarchy (clarity and priority of goals), the validity of the causal theory underlying the policy, the adequacy of financial resources allocated, the integration of implementing agencies within a coherent hierarchy, the formal rules for decision-making (including veto point minimization), and the formal access provisions for outsiders. Together these determine how much guidance the statute gives implementers .

Critics, particularly scholars associated with bottom-up approaches, argued that the Mazmanian-Sabatier framework is primarily top-down and neglects state and local governments as autonomous agents. It also downplays the goals and strategies of target groups as critical variables, assumes a single dominant federal statute, and fails to adequately conceptualize the variety of political pressures within states. The framework neglects the importance of multiple laws and market incentives in shaping target group behavior .

The book applies the framework to several policy domains to demonstrate its utility, with case studies examining implementation across programs of different scope and complexity. The case studies served to illustrate how the independent variables—problem tractability, statutory structuring, and non-statutory factors—interact to determine implementation success or failure. A reviewer noted that while the cases involve programs of very different funding levels, geographic coverage, and target group sizes, they collectively demonstrate the framework's diagnostic power .

Implementation and Public Policy (1983) is a distinct earlier work that predates and is separate from the Advocacy Coalition Framework. The implementation framework is top-down in orientation, focusing on how statutes can be designed to guide implementers toward stated goals. The ACF, developed later, shifted to a broader understanding of policy change over decades, emphasizing competing coalitions, belief systems, and external shocks rather than statutory structuring. The two frameworks address different questions and operate at different levels of analysis.
