It is 9am in Krasnoyarsk, western Siberia. Oleg Deripaska, Russia's second richest man, has headed from his Gulfstream private jet to the boardroom at Kraz, the world's second largest aluminium smelter and the heart of his UC Rusal

The two men are standing in front of a flow-chart and speaking about Kraz's gemba, the Japanese word for factory floor. Mr Deripaska has become an enthusiastic convert to the Toyota "way", as taught by Mr Youmans. "Don't call me a guru, I'm a coach," the latter says.
