The subject of leadership has received special attention in organisational studies, given the centrality of this phenomenon to management. Although they don't specifically use this nomenclature, both Taylor and Fayol began their contributions to the study of organisational behaviour at the beginning of the 20th century, more precisely in 1911, with the publication of Frederick W. Taylor's book The Principles of Scientific Management. The basic approach of this study, which is among the situational perspectives - which is part of the Contingency approach - is the Situational Leadership Theory, proposed by Hersey and Blanchard, which is the result of this evolution of studies on the subject of leadership. For these authors, the success model is achieved by choosing the right leadership style related to the level of maturity (or readiness) of the team members in a given situation, i.e. a theory with a central focus on those being led.
