Holacracy Community of Practice Archive, 2015-2019 Community Holacracy Web Site

It seems to me that a lot of coaching opportunity is available here for the super circle Lead Link and others. That individual seems to be thinking as a manager or department head, and that they control what happens 'below' them.

That's not Holacracy.

What actual live need (tension) does that person perceive? Is there a problem or a lack that the existence of that sub-sub-circle creates? 

Is that sub-sub-circle functioning? Look at meeting record, ask Facilitator to audit. If it's an empty shell then maybe there is a process breakdown and Facilitator can intervene to restore process.

In the course of our effort we have at time created sub-circles out of imagineered design rather than real tension, then they withered due to inactivity and were collapsed.

But like Brian said, that LL has no say in how the sub-circle is structured (with or without additional sub-circles) as long as it is fulfilling its purpose & accountabilities.
