Are 'qualified' and 'competent' the same thing?

I've just contributed to an interesting debate on a forum.  The question which was originally posed related to an HR Manager who, at audit, had said that qualified and competent were the same thing.  The person who posed the question sought the views of other auditors on this.  My response was that in discussions regarding qualifications, training and competence I regularly use the example of someone who has just passed their driving licence and is therefore 'qualified' to drive.  They will almost certainly have had some training too.  Does this guarantee that they are they competent?  No it doesn't, and based on my own recollection of getting behind the wheel after passing my test they are probably not competent (yet).   Using examples like this can help with understanding, no matter where folk sit in an organisation!
