David Coleman has been studying collaboration for over 20 years and has written 4 books on the topic (2 more in process). He works with successful collaboration vendors who are frustrated and are feeling a lot of pressure from competition and providing results to their investors. He also works with end-user organizations spending $millions on collaboration technologies, yet these tools are not meeting their needs. He is currently offering those that sign up for his newsletter (Profitable Collaboration) a white paper on the 10 biggest mistakes collaboration vendors make. Or the 10 traps most organizations fall into when implementing collaboration. David writes for GigaOM Pro and many other publications.
