Rotation

Rotation is a basic organising principle where different participants take up rotating roles. For example, first person 'A' is the co-ordinator and person 'B' is taking care of the outreach. Then later on it reverses. Like this everyone can learn the skills needed.

Downsides

 * 1) Not always is the best person suitable for the job doing that work.
 * 2) Neither are you always doing the thing you like the most.

Upsides

 * 1) Everyone can learn the skills needed to perfom the actions
 * 2) The organisation has a whole will progress as empathy and understanding is higher of other functions
 * 3) No-one will get attached to a certain function

Variations

 * Participants can subscribe for certain functions, not all, so that downside 2 is taking into account
 * Rotating doesn't happen suddenly, with enough participants person 'A' can first work together with person 'B' on the same function, until person 'B' reached the level needed to perform the function well enough

Examples
Food-cooperatives are often organised according to rotating principles. Also, in the old Greek 'democracies' rotation by lot took place for citizens to take different roles of administrator.
