The ability to control or influence people, situations and resources in order to obtain desired results is power. Power can be used both positively and negatively depending on the intent and execution. Power is a key tool in leadership. It allows a leader, when used correctly, to set performance expectations, motivate team members, take decisions with authority and assert themselves.
At the same time, however, power must always be wielded responsibly – i.e., not abused in order to bully or intimidate others but instead used in such a way that the needs of the group are balanced against those of individuals within it. Good leaders should strive to build a culture of mutual respect, where people feel comfortable speaking their minds without worrying about the consequences.
