Targets to be met, including level of performance. The manager's job is to help everyone achieve his or her level of competence. Although some evaluation systems rank order employees, usually they should not be rated on a curve but individually. Standards may involve quality of performance, quantity and meeting established goals. In law enforcement, quality rather than quantity is most important. Standards allow supervisors to be fair and consistent in promotions, awards and discipline. They should be mission related, measurable, attainable, and practical to monitor. Numerical or quantity standards are easier to meet and evaluate, but many law enforcement tasks do not lend themselves to quantitative standards. Reports can also be used to measure performance. Activity reports indicate types and numbers of tasks performed while the number of citizens complaints or commendations also indicate performance quality.
