The term "leadership impact" refers to the influence that a leader has on their followers, organization or community. It is an assessment of how much change or difference a particular leader has made in the lives of those they lead through their actions and decisions. This can be measured by observing changes in behavior, attitudes, performance, and overall success of the group or individuals being led. A positive leadership impact would indicate that the leader has been effective in inspiring, motivating, and empowering others to achieve their goals, while a negative impact may suggest that the leader's actions have had a detrimental effect on those they lead.
