UserVoice use of Trello and Google Docs

Our development process spans 6 different Trello boards. The focal point of all of these boards is the Current Development board. The goal of all the other boards is to feed cards (representing either an enhancement or a bug, more on these in a minute) into the Current Development board and specifically into its Next Up column. The Next Up column is THE single prioritized list that all of the product team (developers & designers) looks at when they’re ready to take a new card to work on.
