Our team recently took on a project that needs a lot of written material. We thought we could handle it ourselves, but now our normal work is being delayed because everyone is busy writing. We are considering whether to outsource ghostwriting for part of the project. Has anyone done this with a team before? How did you share information with the writer? Did outsourcing make things easier, or did explaining the project take just as much time? I would really appreciate hearing what worked for others.
