Hi Rima,
The term “Competencies”, “Competence”, and “Competent” refer to a state or quality of being able and fit. The English Dictionary describes the word Competence as the state of being suitable, sufficient, or fit. The work place definition of Competency refers to a person's fitness with reference to his or her job. In the work context, however, competence has two variations that differ in their meaning, depending on organizational frames of reference.
The two terms arise from different streams of though on the concept of fitness at work. They are:
1. Competency which is a description of behavior, and
2. Competence which is a description of work tasks or job outputs.
Despite the generally accepted distinction in meaning as given above, the terms are still interchangeably used causing them to mean different things to different people. There are also many who wonder if there is any difference between the two terms.
Let me know if you need any more details regarding these.
Regards,
Kalyan.
