Ability of a person to do a job properly
Competence is the set of demonstrable personal characteristics or KSAOs (Knowledge, Skills, Abilities, and Other characteristics) that enable job performance at a high level with consistency and minimal difficulty. Competency in human resources is an organizational criterion for excellence that encompasses the behaviors, experience, knowledge, skills, and abilities that enable employees to perform their roles effectively and reliably.[1][2]
Some scholars see "competence" as an aspect that can be developed through training because it is a combination of practical & theoretical knowledge which involves cognitive skills, behavior, and values used to improve performance. Competency is the state or quality of being adequately or well qualified, possessing the ability to perform a specific, measurable job. For instance, competency needed for management, depending on the sector, might include system thinking and emotional intelligence, as well as skills in influence and negotiation.
