From the very beginning, Riggs made a great effort in searching for an objective and effective model for analyzing public administration in developing regions. With his background in sociological theory, Riggs created the “fused-prismatic-diffracted model.” This model covers a wide range of research. For instance, economic life, social structures, political symbols, and the allocation of power are all part of the analysis of structural function. From the perspectives of heterogeneity, overlapping, formalism, and social transformation, the model observes peculiar characteristics in prismatic society. Even though the theory behind it needs refinement, it has exerted tremendous influence on the understanding of public administration and organizational behavior.
