I'm not so sure if the number of people from a minority available for hire is fixed. It might be possible to target people who are currently not part of the workforce.

I'm thinking of things like offering part time positions. If you offer part time positions, you might reach mothers that might otherwise stay at home with their kids.

I have no clue if this specific measure would help, but I do believe that as a company you could do more to encourage diversity than just wait for someone else to fix the pipeline.
