The technology sector has traditionally been dominated by men. In 2015, Google, Apple, and Facebook all reported the ratio of men to women in their organization was 7 to 3. However, while companies are working on diversifying their workforce, the culture of the industry has been slow to change and 52% of women are leaving the tech industry. More recently, there has been a flurry of activity around empowering women. However, gender equality is not only a women’s issue. True equality requires involvement from everyone—both men and women. This project explores the challenges men face in supporting women within their technology organizations; without addressing the barriers men face we will not be able to realize the full potential and benefits of their advocacy. The project uses participatory design and generative research to co-create and prototype a toolkit of resources for male advocates.
