The origins of performance management can be traced back to the 1960s when behavioral scientists began applying learning principles to real world performance issues. Traditional performance management methods like quotas, targets, and top-down control are still widely used despite criticism. A new understanding of motivation and responsibility is needed. Problems cannot be solved using the thinking that created them. Key principles of an effective performance management system include analyzing current performance, being specific in goals and standards, measuring performance, providing feedback, and delivering positive consequences for desired behaviors.
