Sir/SIEN: A communication protocol for production outages

I’ve spent the last 14 years in PM and Engineering roles. One thing I've consistently seen is that the technical skill of fixing a P0 is often undermined by the 'soft skill' of reporting it to leadership.

Engineers often over-explain, while CEOs just want to calculate business risk. I’ve been using these two frameworks (SIR/SIEN) to decouple technical investigation from executive communication. I'm curious if other teams have formalized communication protocols, or if it's mostly handled by a 'shield' person (like a Director or Senior PM)?
