Chapter 4 Fit as Moderation and Matching: A Test of Strategy and Structure Congruence in Relationship to Performance

Abstract

Many researchers and executives have viewed fit as a key to organizational survival and high performance (Summer et al., 1990). However, the type of fit and how it can be best achieved may often be in question (Venkataraman, 1989). The current study empirically examines both external and internal fit as predictors of firm performance where: (1) external fit is the alignment of, or congruence between, the organization's strategy and/or structure and the task environment, and (2) internal fit is the multidimensional matching of strategy with structure. The argument presented here is that both internal and external fit can, and do, occur simultaneously. Further, the presence of one type of fit may compensate for deficiencies in the other. Using fit in terms of both matching and moderation, hypotheses are tested to determine the nature of both internal and external fit of strategy and structure. Testing of the hypotheses is conducted using data from the medical group industry. Findings support the influence of individual strategy and structure variables on medical group performance. However, fit found between strategy and structure, be it as matching or moderation, shows little influence on performance. Implications for medical groups and the broader health care industry are discussed.
