I would never have expected to see anything related to the political process as a model for business collaboration - but I guess this is part of "change". Just a couple of (old-ish by now) links to anecdotal evidence of how powerful web-based collaboration can be. In these examples, it was Google Docs (spreadsheets) used as a tool in the 2008 US presidential campaign process...
From Huffington Post:
"While the presidential contenders had enlisted technologies such as Facebook, YouTube, Twitter and LinkedIn, which all received a great deal of attention, it was Google Docs which had the most amount of influence, in spite of receiving the least amount of attention.
... The Obama campaign was aware that this had become a major player in the grassroots space, sparking a revolution in the way people self-organize and conduct grassroots efforts and political campaigns. Since a campaign is constantly on a quest for money and voters, Obama's grassroots organization valued agility over hierarchy; online collaboration became a necessity."
"All of us have access to the data, and Google has quick and easy ways to share that data (while retaining the privacy of our volunteers) with the Oakland Campaign headquarters.
... With the advent of Google Docs, what was once a fact of life in community organizing, the lost, corrupted and out-of-date sign-in sheet, has become a much more powerful tool."
