That's a complex topic, that I don't have any experience with.
Fortunately, there are people who know much more about it - and they are easy to find if you google for "offshore scrum", which I'd suggest you do! And don't hesitate to ask more specific questions here!
The soul is dyed the color of its thoughts. Think only on those things that are in line with your principles and can bear the light of day. The content of your character is your choice. Day by day, what you do is who you become. Your integrity is your destiny - it is the light that guides your way. - Heraclitus
