- • Hire QEs who think like users—not just testers who find bugs
- • Coach your team to advocate for quality, not just report defects
- • Run 1:1s that build automation skills and product intuition
- • Give feedback that elevates testing from gatekeeper to quality partner
- • Remove blockers—fight for test environments, time in the release cycle, and respect
