Most leaders think trust is an outcome of success. The best leaders know it's the foundation.

Your next transformation, AI investment, or growth strategy depends on people being willing to act. But what happens when they no longer trust you? Employees question the systems they are asked to adopt, customers doubt the brands they once relied on, and leaders struggle to keep pace with shifting expectations. Trust determines whether people embrace change, buy again, contribute their best ideas, or walk away. For organizations facing constant disruption, those decisions can determine whether an investment delivers—or stalls.

In The Trust Advantage, bestselling author and Deloitte Consulting LLP principal Ashley Reichheld offers a practical guide to making trust your organization's operating infrastructure—built into how decisions are made, work gets done, and relationships are sustained. Drawing on years of research, field experience, and the proprietary TrustID system she developed, Reichheld shows how trust can be measured, managed, predicted, and deliberately strengthened across teams, customers, and partners. Throughout the book, coauthor Simona Spelman, leader of Deloitte's US Human Capital practice, brings readers inside the leadership decisions that test trust—and how to navigate them—from guiding teams through transformation to repairing a client relationship when it nearly falls apart.

Through case studies and real-world examples, the authors show how Humanity, Transparency, Capability, and Reliability shape behavior—and how leaders can act on each to improve performance. Readers will learn to diagnose trust gaps, design experiences that earn trust, and build the conditions for faster technology adoption, stronger customer loyalty, and teams willing to take initiative.

The Trust Advantage equips leaders to make trust a repeatable source of business value, with ideas and tools they can put to work immediately.
