I have certainly seen US and UK leaders in Europe who struggle. They personally might not have the tolerance for ambiguity and go into meetings where things do not seem bolted down - yet the numbers are good and they scratch their heads and wonder how.

When in any new culture, it's common sense to demonstrate basic restraint, tolerance and to show a desire to learn. To me, that is more about engendering good relations than going in holding a business card and saying if I do this at least they will think I have tried.

Too much at the moment can be left until after the decision is made.

I have seen and been involved in acquisitions where that big question is left unanswered.

If IT directors can't answer that, they are not managing their portfolio.

They were prepared to play the long game.
