Portrait of Esther Derby
Esther Derby
I started my career as a programmer, and over the years I’ve worn many hats, including business owner, internal consultant and manager. From all these perspectives, one thing became clear: our level of individual, team and company success was deeply impacted by our work environment and organizational dynamics. As a result, I have spent the last twenty-five years helping companies design their environment, culture, and human dynamics for optimum success.

I’ve written over 100 articles and co-authored two books–Agile Retrospectives: Making Good Teams Great and Behind Closed Doors: Secrets of Great Management. I write about management, leadership, collaboration, organizations and change (or another topic I’m currently exploring).

I’m an original founder of the Scrum Alliance and the AYE Conference, and I have served two terms on the Board of Directors for the Agile Alliance.
