Implementation

POSC 315 • Introduction to Public Policy - Part 1

Transforming Policy into Practice

Today's Agenda (Part 1)

  • Learning Objectives
  • Why Implementation Matters
  • 1st Generation: Case Study Foundations
  • 2nd Generation: Theory Building
  • Case Study: National Speed Limit

Learning Objectives

By the end of this session, you will be able to:

  • Explain why implementation is critical in the policy cycle
  • Differentiate among generations of implementation scholarship
  • Analyze real-world examples of policy rollout successes and failures
  • Identify strategies to improve implementation outcomes

Why Implementation Matters

The Reality Gap

  • Policy → Action gap: legislation alone doesn't change outcomes
  • Frontline discretion shapes how rules affect communities
  • Opportunity for stakeholder influence & conflict

Implementation is where policy meets reality.

1st Generation: Case Study Foundations

Period: 1960s–70s

Key Works:

  • Derthick's New Towns in Town
  • Pressman & Wildavsky's Implementation

Focus: Understanding why programs fail

1st Generation Lessons

Key Discoveries

  • Executive commitment is vital
  • Design must reflect local needs & capacity
  • Joint action complexity across agencies creates challenges

These early studies revealed implementation as a distinct field of study.

2nd Generation: Theory Building

Period: 1980s–90s

Characteristics:

  • Rise of top-down & bottom-up models
  • Sought unified theory
  • Over-relied on rationality assumptions

Top-Down Models

Approach

  • Hierarchical control → clear goals
  • Emphasis on central authority and compliance

Trade-offs

  • Pros: Accountability, clear authority
  • Cons: Ignores frontline realities, federalism

Bottom-Up Models

Approach

  • Begins with street-level implementers and target groups
  • Uses Backward Mapping from desired outcomes

Trade-offs

  • Pros: Local adaptation, discretion
  • Cons: Variable outcomes, power imbalances

Case Study: National Speed Limit (1974–95)

The Policy

  • Federal mandate: 55 mph to save fuel & improve safety
  • States implemented to avoid funding loss
  • Outcomes varied across states
  • Repealed amid differing local priorities

The National Maximum Speed Law (NMSL) in 1974

Reflection Questions

  1. What made the speed limit policy difficult to implement uniformly?
  2. How did federal-state relationships affect outcomes?
  3. What does this case teach us about top-down vs. bottom-up approaches?

Part 1 Summary

Key Points:

  • Implementation emerged as distinct field in 1960s-70s
  • Early case studies revealed complexity of joint action
  • 2nd generation developed competing theoretical models
  • Top-down vs. bottom-up debate shaped the field

Next: Part 2 - Modern Implementation Theory

Coming up:

  • 3rd Generation: Networks & Dialogue
  • 4th Generation: Program Focus
  • Best Practices & Common Pitfalls
  • Practical Applications
