I tend to agree with Marcus Buckingham (First, Break all the Rules). Do you? What's been your experience with "competencies"?
"Competencies are part skills, part knowledge and part talent. They lump together, haphazardly. Consequently, even though designed with clarity in mind, competencies can wind up confusing everybody. Managers soon find themselves sending people off to training classes to learn such 'competencies' as strategic thinking or attention to detail or innovation. But these aren't competencies. These are talents. They cannot be taught. If you are going to use competencies, make it clear which are skills or knowledge and therefore can be taught, and which are talents and therefore cannot."
