What is the best leadership style? By now, you must have realized that this may not the right question to ask. Instead, a better question might be: under which conditions are different leadership styles more effective? After the disappointing results of trait and behavioral approaches, several scholars developed leadership theories that specifically incorporated the role of the environment. Researchers started following a contingency approach to leadership—rather than trying to identify traits or behaviors that would be effective under all conditions, the attention moved toward specifying the situations under which different styles would be effective.

Situational Leadership

Another contingency approach to leadership is Kenneth Blanchard and Paul Hersey’s Situational Leadership Theory (SLT) which argues that leaders must use different leadership styles depending on their followers’ development level. According to this model, employee readiness (defined as a combination of their competence and commitment levels) is the key factor determining the proper leadership style. This approach has been highly popular with 14 million managers across 42 countries undergoing SLT training and 70% of Fortune 500 companies employing its use.http://www.situational.com/Views/SituationalLeadership/RightHereRightNow.aspx

The model summarizes the level of directive and supportive behaviors that leaders may exhibit. The model argues that to be effective, leaders must use the right style of behaviors at the right time in each employee’s development. It is recognized that followers are key to a leader’s success. Employees who are at the earliest stages of developing are seen as being highly committed but with low competence for the tasks. Thus, leaders should be highly directive and less supportive. As the employee becomes more competent, the leader should engage in more coaching behaviors. Supportive behaviors are recommended once the employee is at moderate to high levels of competence. And finally, delegating is the recommended approach for leaders dealing with employees who are both highly committed and highly competent. While the SLT is popular with managers, relatively easy to understand and use, and has endured for decades, research has been mixed in its support of the basic assumptions of the model. Therefore, while it can be a useful way to think about matching behaviors to situations, overreliance on this model, at the exclusion of other models, is premature.

Path-Goal Theory of Leadership

Robert House’s path-goal theory of leadership is based on the expectancy theory of motivation. Expectancy theory of motivation suggests that employees are motivated when they believe—or expect—that (1) their effort will lead to high performance, (2) their high performance will be rewarded, and (3) the rewards they will receive are valuable to them. According to the path-goal theory of leadership, the leader’s main job is to make sure that all three of these conditions exist. Thus, leaders will create satisfied and high-performing employees by making sure that employee effort leads to performance, and their performance is rewarded. The leader removes roadblocks along the way and creates an environment that subordinates find motivational.

The theory also makes specific predictions about what type of leader behavior will be effective under which circumstances. The theory identifies four leadership styles. Each of these styles can be effective, depending on the characteristics of employees (such as their ability level, preferences, locus of control, achievement motivation) and characteristics of the work environment (such as the level of role ambiguity, the degree of stress present in the environment, the degree to which the tasks are unpleasant).

The path-goal theory of leadership has received partial but encouraging levels of support from researchers. Because the theory is highly complicated, it has not been fully and adequately tested. The theory’s biggest contribution may be that it highlights the importance of a leader’s ability to change styles, depending on the circumstances. Unlike Fiedler’s contingency theory, in which the leader’s style is assumed to be fixed and only the environment can be changed, House’s path-goal theory underlines the importance of varying one’s style, depending on the situation.

Vroom and Yetton’s Normative Decision Model

Yale School of Management professor Victor Vroom and his colleagues Philip Yetton and Arthur Jago developed a decision-making tool to help leaders determine how much involvement they should seek when making decisions. The model starts by having leaders answer several key questions and working their way through a funnel based on their responses.

Let’s try it. Imagine that you want to help your employees lower their stress so that you can minimize employee absenteeism. There are a number of approaches you could take to reduce employee stress, such as offering gym memberships, providing employee assistance programs, establishing a nap room, and so forth. Let’s refer to the model and start with the first question. As you answer each question as high (H) or low (L), follow the corresponding path down the funnel.

1. Decision significance. The decision has high significance because the approach chosen needs to be effective at reducing employee stress for the insurance premiums to be lowered. In other words, there is a quality requirement to the decision. Follow the path through H.
2. Importance of commitment. Does the leader need employee cooperation to implement the decision? In our example, the answer is high, because employees may simply ignore the resources if they do not like them. Follow the path through H.
3. Leader expertise. Does the leader have all the information needed to make a high-quality decision? In our example, leader expertise is low. You do not have information regarding what your employees need or what kinds of stress reduction resources they would prefer. Follow the path through L.
4. Likelihood of commitment. If the leader makes the decision alone, what is the likelihood that the employees would accept it? Let’s assume that the answer is Low. Based on the leader’s experience with this group, they would likely ignore the decision if the leader makes it alone. Follow the path from L.
5. Goal alignment. Are the employee goals aligned with organizational goals? In this instance, employee and organizational goals may be aligned because you both want to ensure that employees are healthier. So let’s say the alignment is high, and follow H.
6. Group expertise. Does the group have expertise in this decision-making area? The group in question has little information about which alternatives are costlier or more user friendly. We’ll say group expertise is low. Follow the path from L.
7. Team competence. What is the ability of this particular team to solve the problem? Let’s imagine that this is a new team that just got together and they have little demonstrated expertise to work together effectively. We will answer this as low, or L.

Based on the answers to the questions we gave, the normative approach recommends consulting employees as a group. In other words, the leader may make the decision alone after gathering information from employees and is not advised to delegate the decision to the team or to make the decision alone with no input from the team members.
