Despite important advances in recent years, no agreement exists concer
ning what constitutes management excellence. Specific knowledge of how
managerial behaviour is perceived and evaluated by others will help t
o resolve unsettled questions about what is meant by management excell
ence and improve the actual decisions of managers. This article examin
es the determinants of managerial excellence as perceived by corporate
CEOs, directors, and financial analysts in Fortune magazine's annual
survey of the best-managed American firms in 33 industries. While the
firms perceived to be best managed are more profitable and less risky,
and grow faster and reward their stockholders more than less well-man
aged firms, these variables explain only about 30 per cent of the vari
ance in management ratings. The firms perceived to be best managed hav
e more involvement in international markets and research and developme
nt, while large firm size and firm diversification reflect negatively
upon perceived managerial quality. The relative inability of conventio
nal financial measures of firm performance to explain perceptions of m
anagerial excellence underlines the complex nature both of these perce
ptions and strategic behaviour. The results support Varadarajan and Ra
manujam's conclusion that excellent management depends upon a diverse
set of competencies and values, as well as Chakravarthy's contention t
hat the most important characteristic of firm performance is managemen
t's ability to transform the firm and adapt to a rapidly changing envi
ronment. By contrast, little support is found for the maximization of
stockholder wealth criterion of Rappaport.
