Abstract:

Double agents on writing teams provide benefits to both product developers and technical writers with their unique skills and perspectives. You'll be more likely to get the information you need when you need it because your double agent has already set the stage for success. Learn the benefits of having a double agent working with technical writers as a part of the product development team. Discover valuable secrets never before divulged to the public that you can use to work with your product developers. Take out your magnifying glass and look for the clues.
