Mumford, Zaccaro, Harding, Jacobs, and Fleishman have argued that leadershi
p can be understood in terms of knowledge, problem-solving skills, solution
construction skills, and social judgment needed to solve organizational pr
oblems. In this article, we review the results obtained in a series of inve
stigations intended to examine this proposition. We begin by reviewing the
central implications of this skills-based model of leader performance. The
strengths and limitations of the available evidence bearing on this model a
re discussed along with some potential directions for future research. Rese
arch directions are considered with respect to model development and refine
ment, linkages to other models of leadership, and potential practical appli
cations. It is argued that this kind of skills-based model may provide a vi
able new perspective for understanding leader performance-one particularly
appropriate for the dynamic, knowledge-based industries of the twenty-first
century.
