You have 3 lanes, TODO, DOING, DONE.<p>Have a max of Work In progress that can be in the DOING lane based on size of team. Once that limit is hit, nothing else can move into the DOING lane, if other's are finished, they go help others until work starts moving into the DONE lane.<p>DONE means DONE, if it needs QA, Documentation, install script, whatever, it stays in DOING until it's truly DONE.
