User documentation is part of your definition of "Done." However, there aren't enough technical writers for all teams. Your Development Team doesn't have a technical writer. What should you do? (choose the best answer)
Form a separate team of technical writers that will work on an on-demand basis for the various Product Owners. Work order will be first in, first out.
Your Development Team is still responsible for creating user documentation. In this case, the Development Team members will write it.
Wait until you have a technical writer on your Development Team to take care of this.
Let the user documentation remain undone and accumulate until after the last development Sprint. It will then be done by any available technical writers.
