This is a perenial problem isn't it?
It's easy enough to have a competency framework but how can you measure improvements in a consistent systematic manner.
Appraisal and performance management are can help but they're are not an exact science.
In addition how can training be measured so that it's contribution to improved competency (or otherwise) can be assessed?
Counting the number of days somebody attends training isn't the answer - that just measure training activity, not learning or behaviour change.
Any ideas? Any pointers?
