In 1938, Lewin and Lippitt proposed classifications of leaders based on how much involvement leaders placed into task and relationship needs. This range of leadership behaviors was expressed along a continuum by Tannebaum & Schmidt in 1973, ranging from boss-centered (task) to subordinate-centered (relationship).To choose the most appropriate style and use of authority, the leader must consider:
- Forces in the manager: belief in team member participation and confidence in capabilities of members.
- Forces in the subordinate: subordinates who are independent, tolerant of ambiguity, competent, identify with organizational goals.
- Forces in the situation: team has requisite knowledge, team hold organizational values and traditions, teams work effectively.
- Time pressure: need for immediate decision under pressure mitigates against participation.
- Gives managers a range of choices for involvement.
- Presents criteria for involvement and delegation.
- Focuses decision maker on relevant criteria (e.g., forces & time).
- Emphasizes employee development and empowerment.
- Is heuristic--encourages research to see how effective delegation may be under the model.
- Involves only the initial step of assigning a task to someone, not the following processes that may determine the effectiveness of the outcome.
- Assumes the manager has sufficient information to determine disposition to self or team.
- Assumes "neutral" environment without social bonds or politics.
- Simplifies complex decisions to a two-polar dimension; more simple than reality is.
