The amount of process and ceremony required is inversely proportional to the trust level on the team.
Once we had some difficult conversations and realigned expectations, we found our daily standup was extremely redundant. Team members began to realize that others would simply reach out as needed. Everything is much more async now. Only 3rd party interactions require explicit scheduling these days. Prod down, vendor integrations, etc.
Other observations: We seem to somehow spend more time on adhoc calls than our prior scheduled calls, but A Lot More (tm) is getting done regardless. Stress levels seem down as well. Weird how you can have cake and eat it too sometimes.
I don’t know if I would sit here and proclaim that process is exclusively a bandaid for lack of trust, but it certainly seems like one indicator of this condition.
