Core Leadership Theories
The Four Core Theory Groups
Let's
look at each of the four core groups of theory, and explore some of the tools
and models that apply with each. (Keep in mind that there are many other
theories out there.)
1. Trait Theories – What Type of
Person Makes a Good Leader?
Trait
theories argue that effective leaders share a number of common personality characteristics,
or "traits."
Early
trait theories said that leadership is an innate, instinctive quality that you
do or don't have. Thankfully, we've moved on from this idea, and we're learning
more about what we can do to develop leadership qualities within ourselves and
others.
Trait
theories help us identify traits and qualities (for example, integrity,
empathy, assertiveness, good decision-making skills, and likability) that are
helpful when leading others.
However,
none of these traits, nor any specific combination of them, will guarantee
success as a leader.
Traits
are external behaviors that emerge from the things going on within our minds –
and it's these internal beliefs and processes that are important for effective
leadership.
2. Behavioral Theories – What Does a
Good Leader Do?
Behavioral
theories focus on how leaders behave. For instance, do leaders dictate what
needs to be done and expect cooperation? Or do they involve their teams in
decision-making to encourage acceptance and support?
In
the 1930s, Kurt Lewin developed a framework based on a leader's behavior. He
argued that there are three types of leaders:
1. Autocratic leaders make decisions without consulting
their teams. This style of leadership is considered appropriate when decisions
need to be made quickly, when there's no need for input, and when team
agreement isn't necessary for a successful outcome.
2. Democratic leaders allow the team to provide input
before making a decision, although the degree of input can vary from leader to
leader. This style is important when team agreement matters, but it can be
difficult to manage when there are lots of different perspectives and ideas.
3. Laissez-faire leaders don't interfere; they allow people
within the team to make many of the decisions. This works well when the team is
highly capable, is motivated, and doesn't need close supervision. However, this
behavior can arise because the leader is lazy or distracted; and this is where
this style of leadership can fail.
Clearly,
how leaders behave affects their performance. Researchers have realized,
though, that many of these leadership behaviors are appropriate at different
times. The best leaders are those who can use many different behavioral styles,
and choose the right style for each situation.
3. Contingency Theories – How Does
the Situation Influence Good Leadership?
The
realization that there is no one correct type of leader led to theories that
the best leadership style depends on the situation. These theories try to
predict which style is best in which circumstance.
For
instance, when you need to make quick decisions, which style is best? When you
need the full support of your team, is there a more effective way to lead?
Should a leader be more people-oriented or task-oriented? These are all
questions that contingency leadership theories try to address.
You
can also use the Leadership Process Model to
understand how your situation affects other factors that are important for
effective leadership, and how, in turn, these affect your leadership.
4. Power and Influence Theories –
What is the Source of the Leader's Power?
Power
and influence theories of leadership take an entirely different approach –
these are based on the different ways that leaders use power and influence to
get things done, and they look at the leadership styles that emerge as a
result.
Perhaps
the best-known of these theories is French and Raven's Five Forms of Power .
This model highlights three types of positional power – legitimate, reward, and
coercive – and two sources of personal power – expert and referent (your
personal appeal and charm). The model suggests that using personal power is the
better alternative, and that you should work on building expert power (the power that comes
with being a real expert in the job) because this is the most legitimate source
of personal power.
Another
leadership style that uses power and influence is transactional leadership . This
approach assumes that people do things for reward and for no other reason.
Therefore, it focuses on designing tasks and reward structures. While this may
not be the most appealing leadership strategy in terms of building
relationships and developing a highly motivating work environment, it often
works, and leaders in most organizations use it on a daily basis to get things
done.
