Internally, collaboration has never been better or easier. Using ProofHQ and Workfront's comment features, we can easily discuss a project and have that be a part of the official record. We can work far more easily with all of our employees no matter where they are and Work simultaneously to more easily meet difficult deadlines. We had one instance where an editor was marking up a PowerPoint presentation, while our medical writer collaborated and answered questions while our Desktop artist followed them and made the changes as they were written. Its not how we normally operate, but we hit that deadline hardly breaking a sweat.
As for external collaboration, its only been tried by a few brave employees and our clients who are willing to try something new. I'm confident that with time, many more of our clients will be directly collaborating with us using Workfront and ProofHQ.
