The place where I work, we discuss the estimates until we agree on a shared estimate. If there are no outliers, we just take the average.

We usually start by discussing the outliers on both sides.

This makes it easy to uncover simpler solutions (if everyone had a higher estimate) or pitfalls (if everyone had a lower estimate).

Yes, that's exactly what I meant to describe.
