 So I've got a little bit of experience with the dynamics there and I serve as chief scientist for a company called Valtech and we have an office here with around 600 people and we do agile offshore development and I've helped evolve and create that and I've lived here and I've worked on the other side of the fence as well working with clients who are working with offshore service providers and so forth. So I've kind of worked several sides of this fence If you want to go deeper into this, we have a whole chapter in our book that describes many of the experiments that apply in this domain and we want to get more concrete and there's often an intersection between multi-sites and offshore as well and so we find the tips in that chapter These have been based upon our experiences with respect to nation Let's start now you've some people have questions in their hands and Some of those people were born in the month of January And please hold up your hand if you were born in the month of January All right, let's take your question I'm going to branch for a moment and make a comment that Murray Bovendick has also mentioned and I think is a theme in lean thinking There's no such thing as best practices in domains like R&B It frees the whole idea incorrectly at least in English best means best Which means that there's nothing better And so if you set up a culture with the best practices group and the list of best practices And that immediately freezes you from the idea of continuous improvement and Challenging the status quo right or thinking that in this context of vinyl don't write or since talked about this for many years as well That in different contexts different practices are appropriate So I urge you to expunge from your vocabulary and mindset the idea of best practices I'm quite sure that in repeatable domains like Flying an airplane or a heart surgery there are currently best practices which are relatively context-independent But in young good domains like ours and domains with lots of variability that are highly context-dependent There's no such thing as a best practice Now what was your question again? Please ask your question again I'll just get out of the written words practices for better understanding For collaboration between on-site and offshore team Okay so
