Recently I read a press release by Gartner, Inc., an IT research and advisory firm based in CT, which identifies 5 collaboration myths. The myths are:
1) The right tools will make us collaborative.
2) Collaboration is inherently a good thing.
3) Collaborating takes extra time.
4) People naturally will/will not collaborate.
5) People instinctively know how to collaborate.
I might tweak #3 a bit to reflect those on the other side of that particular myth; Collaborating takes extra time/saves time. And I might want to add a myth about the costs of collaboration. Maybe #6 - Collaboration saves money/is too expensive.
It's a quick read that invites you to challenge your assumptions. Have a look.
