Difficult Feedback Writer

Help me write constructive feedback for [person] about [behavior/performance]. Context: [relationship, history, stakes]. Using the SBI-I model: Situation (when specifically), Behavior (observable, not interpreted), Impact (on me/team/work), and Intent question (what was your intent?). Draft: (1) A written version for async delivery. (2) A spoken version for a 1:1. (3) How to open the conversation. (4) What to do if they get defensive. (5) How to close with a clear agreed path forward.
