In multicultural organizational contexts what could be a good strategy to keep people motivated towards a common task?

I think the motivation in any environment has to be treated the same way, if its on a working, or students, or family environment, it is the same and having multicultural organizations its a good challenge because of misuderstandings.
Taking into account this, I think a really good strategy would have to include the following aspects:

• Have clear rules and give clear instructions 
• Set the benefits that the people is going to get by going the tasks 
• Recompense people by their efforts, trying to be fair
