In the transition from a Newtonian paradigm of control and equilibrium to one of chaos and disequilibrium, organizations have substantially changed their structures (e.g., moving to diverse project‐based teams, advancing knowledge management, and building innovative cultures), but they have only minimally changed their leadership styles and practices. This paper describes a model of leadership proposed by Ron Heifetz that optimizes the characteristics of the 21st century in which the leader's role is to disturb equilibrium, differentiate between technical and adaptive challenges, and engage the followers in solving the organization's problems. This model is contrasted with other leadership models to validate its usefulness in the face of chaos, ambiguity, and rapid change. The commitment of the leader to holding steady in the face of predictably strong resistance and the dangers to the leader in using this model are discussed.
