This document discusses leadership behavior and its study. It outlines that many leadership taxonomies have been proposed due to different levels of abstraction and development methods. Research methods to study leadership behavior include surveys, experiments, and behavior description techniques. Leadership behavior can be described broadly, such as task, relations, and change-oriented behaviors, or specifically, such as planning activities or providing support. Both task and relations behaviors are important for effectiveness, as is understanding, adapting to, and implementing environmental change. Specific effective leadership behaviors include planning, clarifying roles, monitoring, supporting, developing skills, and providing praise.
