Measuring how well activities are done in meeting goals. Proficiency of skills, choice of skills, and ability to execute are all components here. Generally the questions will be about maximizing one's performance or ability to perform tasks.

Performance management (PM) includes activities that ensure that goals are consistently being met in an effective and efficient manner. Performance management can focus on the performance of an organization, a department, employee, or even the processes to build a product or service, as well as many other areas.
