The best person form the job is the person who will make the team perform at its best. Which in IT would probably mean a technically savvy, creative person with good social skills and some domain knowledge. Those would be the merits upon which to build our meritocracy.

So you can be a productive coder or a good presenter or whatever but by themselves, these are incomplete metrics. If you happen to also be an a*hole, you are probably an overall liability.

An even more useless metric, though, is your specific flavour of sexuality or your skin colour. None of these count as qualifications in any sense, and if management if measuring these things I'd be wary of their sense of judgement.
