Expand the definition with a couple of sentences
Competency can be defined as groups of related knowledge, skills and attitudes (KSAs) needed by a person to perform a particular job . It is thus the part of an individual's KSAs which can be observed and evaluated. The concept represents a HRM based view on managing knowledge embedded in individuals and is closely related to qualification of individuals.
The concept of competency is often mixed with the related job-task . Competencies are the mental, physical and behavioral tools with which an activity or a task is executed. When describing competencies a difference should be made between describing the required task and the competencies which allow a person to perform the task to a standard. These competencies may include knowledge and skills which are not directly connected to the specific task. For example to perform a maintenance task a person usually needs to understand the safety relevance of the task.
