In All the Difference, bestselling author and head of the Simmons University Institute for Inclusive Leadership Susan MacKenty Brady, business negotiation expert Stuart D. Kliman, and retired US Army Lieutenant General Leslie C. Smith argue that leaders must shift their view: difference is not just noise to tolerate—it's the raw material for creating value. When difference isn't understood or acknowledged, it breeds disconnection, saps performance, and undermines your team's potential. What's needed is a leadership playbook for turning human difference into your organization's greatest strength.
