Everything is a priority, so put them in order. The team suggests, one person holds the pen, a line marks the real work. $5 a month or $50 a year per team.
In many occasions that i've worked in smaller teams, ordering priorities was always a struggle.
So i've built Penholder to solve that problem: One Penholder edits, the other follow and request changes. Now everybody in my projects knows the order of priorities.
