From a personal perspective, the capacity or ability to direct or influence the behavior of others or the course of events is the exercise of power.

Exercising power others have endowed on you through a role or title (e.g., policeman, manager, organizational leader) is more about others recognizing the authority granted to you.

This type of power is often supported by consequence or penalty if ignored.  For example, ignoring a judge could result in a fine or even imprisonmen ( contempt of court).

Granted power does have some limitations, the motivation for others behaviour is not necessarily a result of agreement but possibly fear of negative consequences.

Earned Power

The exercise of power, whether earned or granted has the same purpose.  The difference is in how the behavioural influence is initiated.

Dictorial behavior is an extreme exercise of granted power.  The person welding the power relies on obedience based on their authority.

In many ways this type of power is easier to weld.  Just do it, is the mantra.  And if you don’t, you’ll be sorry, is the threat.  Intuitively it is obvious this type of power can be the hardest to sustain over time.

Self Motivation

Earned power empathizes the value equation to motivate actions.  Those who exercise earned power create an understanding of the the results and what’s in it for you.

In brief, people follow the influence of earned power because  they want to.  As long as this desire continues, because it makes sense, the behaviour of others can be influenced and is more likely to be executed with passion.

A key attribute of good leaders is the exercise of earned power more frequently than granted.
