Over the past 20 years, U.S. agribusinesses have been subject to a number of significant structural changes. Given that the strategic management literature emphasizes an organization’s fit with its environment as an important determinant of performance, this study examines how strategic planning practices have changed over time. Data for this study was collected from Michigan agribusinesses at two time periods, 1992 and 2012. A comparative analysis indicates that Michigan agribusinesses have become larger, more diverse, and have increased their adoption of strategic planning activities. Furthermore, these practices were found to be positively correlated with performance.
