The Leadership Continuum is a concept that attempts to illustrate the range of possible leadership behavior available to a manager. Their behavioral pattern can be placed from one extreme of complete autocracy to the other extreme of pure democracy. This model was developed by R. Tannenbaum and W.H. Schmidt in 1958 as a continuum leadership model. 
The purpose of the Leadership Continuum is to give managers a framework to understand and interpret their leadership behavior in terms of the degree of authority used by the manager and the area of freedom available to non-managers in arriving at decisions.
The autocratic leadership style is at one end of the continuum, where the manager makes decisions without consulting their team. This style can be effective when quick decisions are needed, but it may lead to low employee morale in the long term.
At the other end of the continuum is the democratic leadership style, where decisions are made collectively with the input and involvement of the team members. This style can lead to high employee satisfaction and better quality decisions due to diverse viewpoints, but the decision-making process can be time-consuming.
In between these two extremes lie various degrees of participative leadership, where managers increasingly involve their team members in decision-making.
The Leadership Continuum highlights that there is no one-size-fits-all approach to leadership. It emphasizes the importance of flexibility and adaptability in leadership based on the situation, the team's capabilities, and the organizational culture.
However, critics of the Leadership Continuum suggest that it oversimplifies the complexity of leadership and does not consider factors such as emotional intelligence, situational factors, and individual personality traits.
An example of the Leadership Continuum in action could be a manager who typically favors a democratic leadership style but switches to a more autocratic approach during a company crisis when quick decisions are necessary. After the crisis, the manager may move back along the continuum towards a more participative leadership style to maintain team morale and engagement.
