GSD in numbers
It is easy to find many papers referencing many other authors who references other authors until a vague case was reported in GDS saying that we have problem X,Y,Z, but it may not apply for the others. What is a simple case of study starts to become a truth just by citating it. Better something than nothing I would say when I have some money in my pocket. For avoiding these kind of situations from sometime to sometime one report appears. And this one is about global software development. You feel rich at that moment thanks to this data.
I am talking about: SIIA Report 2006
I do not know if there is an updated version but I would like to have something similar but with agile GSD.
