Reflections on life at “De Witte Wand”…
I know from my own experience that the most exhillarating (as well as at times, the most frustrating) team I ever worked with was one that, by design, was set up to be as diverse as possible. When we learned how to manage our diversity, we were extremely productive, and came up with great results.
Encouraging diversity is not then about being liberal or tolerant (although it tends to require both) but about being rational.
