Many women sit on different boards. However, they are in a minority position. You need about a third of board members to be women for the board to evolve. Until a board reaches that proportion of women, it will not make any major advances in its governance process.
Then, there is also the competency matrixes. I sit on many boards and support others. The competency matrixes allows us to recruit women, very strong women, that really meet the set criteria. There will be a sort of floating period where men who already sit on boards might fall behind because they will not have been recruited using a competency matrix with many required qualifications. Eventually, they will catch up and everyone will be recruited based on the same criteria.
Nowadays, women who get nominated on boards are very strong. They help the organizations move forward; I see it on many boards.
