I attach a conference paper, some data about the conference and the "acceptation" of that paper, improved, in the Journal of Business Ethics. It will be published soon (I hope). It gives an answer to your question thru the "Sagrada Familia" study case.
Thank you very much for your input. For your info, I'm leading a team that is rewriting the US national policy document on Partnering for highway construction. Coincidentally, the PhD student who is working on this research is from Panama, so documentation in Spanish is both welcome and valuable.
I'll connect with you as we move forward in this research project. If you would like to stay in the loop our progress, please send me an email at my Iowa State University email address found on the web.
SImVision, a project organization simulation software package offered by ePM in Austin Texas http://epm.cc can model a project's workflow and organization structure, predict the required amount of coordination that should be engaged in between different pairs of stakeholders and model where information overload or breakdowns in communication are likely to occur.
