I think it really focuses on the culture of the organization. You can take the public service as an example where leadership has to be driven from the top. The top of the organization has to drive it and they have to drive it down through all the levels of their organization, for example, by looking at how they do promotions, how they bring any candidates before any kind of promotion boards.
Also, I think the second thing would be looking at so-called family friendly policies and how they may disadvantage women instead of actually advantaging them.
