Measuring strategy coherence through patterns of strategic choices

Abstract

Strategies at different levels need to be coherent to ensure competitive advantage (Hofer and Schendel, 1978). Strategy coherence is the consistency of strategic choices across business and functional levels of strategy. In this paper we focus on strategy coherence. Using patterns of strategy, we develop a measure of the extent of strategy coherence. The relationship between coherence and performance is used to validate the measure. We illustrate the application of the measurement and validation process, in the context of acute care hospitals. The results indicate that our measure of coherence is monotonically related to performance. We also find performance differences between more and less coherent hospitals on the industry specific performance indicator of occupancy. Implications for theory and practice are highlighted.
