Most business education courses concentrate on strategy, accounting and economics. Few teach how to look at, and change, a leader’s behaviour.

This was a problem for Hermien Uys, legal counsel for group exploration operations at mining company De Beers . When De Beers develops new operations, Ms Uys helps ensure that they establish the correct company structure, know how many expatriate workers they can bring in and know how local finance laws permit them to get a dividend out. Much of her time is spent on De Beers’ Angolan operations.
