[ Knowledge / Behaviour ]
Defining competency inevitably recognises two aspects: knowledge and behaviour. In our engineers, we want a high level of both.
We want highly knowledgeable professionals who can give us the right answer to any problem within their expertise. Just as important as the right answer, is the accompanying behaviour to a set of professional principles and ethics.
It’s quite possible for individuals to rate highly on one aspect but not the other.
So while we don’t want an ethical person who makes constant mistakes, we also don’t want a person who’s always right but uses it in nefarious or unsafe ways.
