Discretionary coalition – a population engaged in deliberations.

The second pattern from Pava is the social artefact matching the technical one, the deliberation. It was a novel organizing principle where the formal organization chart became scaffolding.

As you see, there has been a proliferation of the principles from Cherns' nine, even more so from the original handful of ones from the origin of STS back in the 50s. So much so that some have seen the need to synthesise them, one being this paper from 2020, which arrived at a total of 20.
