Is there really a truly diverse company, or even close? One that weighs color, gender, ethnicity a naught.
Since ~4yrs, I have markedly noticed serious attention on increased female presence, across the leadership, board and in general. (at least, amongst companies housed in western developed countries)
Yet, I find this shortsighted. For instance, in a global company operating in 50+ countries, with non trivial growth and revenues coming from US, EU and Asian markets - key leadership is always rooted in country of origin.
A German global company never lets power quorum go non-German. Leadership needed in a fast growth asian market? Send a German leader to China for 4 years, instead of hiring a local talent. 40% asian workforce? In 10 years, 0% representation in board, or even corporate executive leadership.
For example, many would argue that your definition (color, gender, ethnicity blind) would not be diversity at all.
