SJWs find an issue in everything. Their solution strikes me as being heavily biased toward quotas and reverse discrimination. They're not so interested in root causes. Finding and remedying root causes is work and work and whining just don't mix well for them.
Only a stupid company (or project or what-have-you) would fail to take advantage of talent. That's one thing I admired about the IBM of some years ago. They made full use of the talent pool without regard to race or gender (at least that's how it appeared to me from the outside). And that's the real answer: Make sure there are no untoward barriers to entry, and then make use of the talent that presents itself.
Anything else, like bemoaning imbalances and immediately ascribing that to prejudice, is just lazy SJW whining, pointing fingers and looking for problems without being willing to work toward real solutions.
 By this I do not mean take in any "underrepresented" member regardless of qualifications or ability. I mean instead, ensure that anyone with ability and interest is not excluded arbitrarily. For instance, give scholarships and work-study opportunities to people with talent but who can't otherwise afford college.
