Competency

How often do hear this word at your workplace?

Been looking at a lot of stuff regarding this for some time now, and it's starting to me make wonder about my own level of competency.

From what I gather (without going too deep into the technical definition, discussions etc.), competency is what an employee is capable of.

Performance, on the hand, is what the employee actually does and achieves.

The details are lengthy and the actual stuff are at the office desk, not with me. Now I see why competencies don't count when our performance is being evaluated.
