Three things that actually reduce your exposure right now, based on the Oracle pattern.

Make sure at least two people outside your direct team know what you own and why it matters. Build one external relationship a week - a former colleague, someone in your network you haven't spoken to in a year. And move at least one piece of your work from process to outcome this quarter. Volunteer for the result, not just the deliverable.

None of this is about learning a new tool. It's about being harder to put in a spreadsheet.

I've been running this checklist on myself. It's uncomfortable. Do it anyway.
