The executive chairman and former CEO of Dunkin' Donuts and Baskin Robbins reflects on the unique, results-oriented discipline he's developed over decades of leadership, which provides a blueprint for any organization to achieve prosperity.

We live in an era in which successful organizations can fail in a flash. But they can cope with change and thrive by creating a culture that supports positive pushback: questioning everything without disrespecting anyone.

Nigel Travis has 40 years of experience as a leader in large and successful organizations, as well as those facing existential crises - such as Blockbuster as it dawdled in the face of the Netflix challenge. In his 10 years as CEO and chairman of Dunkin' Brands, Travis fine-tuned his ideas about the challenge culture and perfected the practices required to build it. He argues that the best way for organizations to succeed in today's environment is to embrace challenge and encourage pushback. Everyone - from the new recruit to the senior leader - must be given the freedom to speak up and question the status quo, must learn how to talk in a civil way about difficult issues, and should be encouraged to debate strategies and tactics - although always in the spirit of shared purpose. How else will new ideas emerge? How else can organizations steadily improve?

Through colorful storytelling, with many examples from his own career - including his leadership in turning around the fear-ridden culture of the London-based Leyton Orient Football Club, of which he is part owner - Travis shows how to establish a culture that welcomes challenge, achieves exceptional results, and ensures a prosperous future.
