From what I understood after I watched it and looked into it a bit more is that individuals have roles within the organization and are able to decide their own actions on how to fulfill that role. The actions are informed by the collective understanding of their goals and norms that are formed during their frequent meetings (which are very different in vibes from regular corporate meetings).

This is how I understood it works for most decisions but there a few decisions that fall back on voting which after the vote occurs the individuals are expected to carry out whatever was voted on.

So like it says in the video it is a largely informal structure but one that seems to work very well.
