Introduction
Ferrel Heady and Fred W. Riggs were major contributors to Comparative Public Administration (CPA), but while Heady emphasized comparative analysis of administrative systems and structures, Riggs explained administration through its interaction with the wider social environment.
Body
Ferrel Heady – Structural-Institutional Focus:
1. Heady compared administrative systems through features such as bureaucracy, political institutions, recruitment, accountability and civil-service structures.
2. His approach was relatively descriptive and comparative, identifying similarities and differences across developed and developing countries.
3. It provides clarity for analysing formal institutions and administrative capacity.
4. However, it may inadequately explain why similar formal structures function differently across societies.
Fred Riggs – Ecological Prismatic Model:
1. Riggs viewed administration as inseparable from its social, economic, cultural and political environment.
2. His Fused–Prismatic–Diffracted model located developing societies in a transitional “prismatic” stage.
3. Prismatic societies display:
- Heterogeneity – coexistence of traditional and modern practices;
- Formalism – gap between formal rules and actual behaviour;
- Overlapping – multiple institutions performing similar functions.
4. His Sala model explains phenomena such as nepotism, administrative corruption and weak institutional differentiation.
Which is More Effective?
Riggs is generally more useful for developing nations because it explains the context behind administrative behaviour, rather than merely describing structures. However, his models are criticised for being overly abstract, deterministic and difficult to empirically verify.
Conclusion
Thus, Heady offers a useful comparative structural framework, but Riggs provides a deeper explanatory tool for developing societies by linking administration with ecology; ideally, both approaches should be used complementarily.
