Not necessarily. The only way to achieve balance is to appoint/promote exclusively on ability/performance, by some pre-defined objective measure. Doing so might achieve the same balance as the wider community, but might not, for reasons quite outside the organisation's control. And, of course it would be a slow process, which is the kind of thing that motivates the calls for quotas - but quotas are always guaranteed to be discriminatory.
