A clear collaboration policy is essential for employees using customer, partner, and internal collaboration tools. While it takes a cross-organizational team to establish a collaboration policy, the technology organization will play an increasingly important role: to steer the policy creation process, embed the policy in tools and training, and educate employees.

This is an update of a previously published report; Forrester reviews and updates it periodically for continued relevance and accuracy.
