Use: "What would make this a clear yes for your team?" That question turns resistance into requirements. Add: "What constraint should we design around so you never have to escalate?" Suddenly you are co-creating. If they hesitate, try, "Would a one-week micro-pilot reduce risk enough to proceed?" Curiosity disarms and discovers value. It proves you care about their success, not just your deliverable, building durable influence session by session.
Say: "Security piloted this approach last quarter; here are their results and the contact who can speak candidly." Referencing respected peers reduces perceived risk. Follow with, "I’ll own the first draft and the first rollback plan." Ownership sweetens the ask. If you lack proof, try, "Here’s the smallest measurable bet that honors your standards." People move when fear is named, proof is visible, and responsibility has a clear home.
