We need something more than "adding" more women in our work context, we need to change the culture and our work organization. In these years we learned many things, mainly that if we want to change something we have to really include the gender dimension in our labs, in our researches, in our management tables. and when I speak of gender, I speak not only of women and for women, but for all.

Looking back while looking forward, a gender target would have seemed revolutionary in 1983. More recently, after ten years of gender and other diversity-related policies and actions, the Diversity and Inclusion Programme at CERN proposed a gender target strategy, “25 by ‘25”. Unanimously endorsed by the Senior Management in 2021, implementation is well underway and interim results are in. What is working and why? Beyond gender, let’s talk about how diversity and inclusion in STEM can be most effective when it is designed for, and with, everyone.
