The effectiveness of strategic planning: competitiveness in the Brazilian supermarket sector

This paper considers the relative impact of management strategic planning practices and economic changes on company performance. The paper focuses on the Brazilian supermarket sector during the period 1988–1999. This was a period marked by significant changes in economic and competitive conditions. Using sales figures as indicators of company performance, ANOVA tests were applied. The results derived suggest that variables representing changes in economic conditions and strategic planning were both statistically significant when they were used to explain performance differences among Brazilian supermarket operations. Differences in company management practices were found to play a more important role than changes in the environment. However, the results clearly suggest that management by itself was unable to take advantage of the upward and downward movements in the economy to modify the relative competitive positions of companies operating within the market. This finding challenges the existing literature on strategic planning.
