The final way to come to a consensus is through a brainstorming session. Each group member will come up with a list of the items that he/she thinks should take priority. These items are then recorded on a blackboard or whiteboard. These items are then numbered and reviewed to ensure that everyone understands each issue.
Group members then write down the top items that they think should take priority. Each person should pick a third of the list. For example, if you have a list of 12 items, each person should pick 4 to work on. If you do not require secrecy, you can do this by a show of hands after reading out items.
The votes are then tallied, and the list cut down to reflect the top items. These items are then discussed. A final vote is either done by paper ballot or hands to choose the one item that takes the top priority.
