What's the Purpose of a 90-Minute PD?

If you are facilitating a 90-minute session with a group that you won't be working with ongoing my first question would be what is the level of psychological safety that exists within this group already. Maybe i do need to spend some time cultivating a context in which people can listen but maybe notMaybe i'm coming into a group that has incredible levels of psychological safety maybe they do listen to each other maybe what they need is a little bit of a primer or a reminder or to be set up to engage in conflict with each other conflict can be super healthy and so that's the first thing that i would wonder about it might be.
