David Nadler: A life of congruence

Abstract

David Nadler was a scholar-turned-practitioner who left his mark on the field of organization development through his work with CEOs and his writing about organizational diagnosis, data feedback, organization design, transformation, and boards. The consulting firm he created, Delta Consulting, was the premier firm specializing in consulting to CEOs on matters related to their personal and organizational effectiveness. He is perhaps best remembered for creating, along with Michael Tushman, the congruence model, which serves as a guide for organizational diagnosis and design. However, his greatest impact was on those who knew him as clients, associates, and friends.
