You're absolutely right.
Setting a quota is a perfectly justified, correct and effective measure, but it isn't the only one. If we only set quotas, there will indeed be appointments but, after a few years, if the organizations haven't put something sustainable in place, we'll have to start again.
Of course, if we set a quota, there will be women on boards of directors. That's a good starting point. However, if we want to see real change within an organization, the managers need to want to change the practices and foster a working environment that will keep women in the organization and hold decision-making positions.
