Written by the founders of Delta, Sim Sitkin and E. Allan Lind, the white paper presents a summary of their model of leadership referred to as the Six Domains of Leadership Model that draws broadly on the social science research literature. It conceptualizes leadership in terms of specific clusters of behaviors that have distinguishable effects on those a person is trying to lead. While there are many theories of leadership and voluminous writings on the subject, this research-based framework is intended to synthesize that work into a systematic, intuitive, and grounded set of behavioral guidelines by which anyone can consciously work to improve their leadership effectively.
