SAFe CREATOR AND CHIEF METHODOLOGIST
Recognized as one of the world’s foremost authorities on Lean-Agile software development practices, Dean Leffingwell, creator of SAFe, is an author, executive, entrepreneur, and methodologist. Alongside SAFe, his best-selling books, including Agile Software Requirements: Lean Requirements Practices for Teams, Programs, and the Enterprise, and Scaling Software Agility: Best Practices for Large Enterprises, form much of the basis of modern thinking on Lean-Agile values, principles and practices. Founder of several successful startups, including RELA, Inc., Requisite, Inc., and Scaled Agile, Mr. Leffingwell also served as Chief Methodologist to Rally Software, and prior to that, as a Sr. Vice President at Rational Software (now part of IBM).
CHIEF METHODOLOGIST AND SAFe FELLOW
As Chief Methodologist, Andrew is passionate about helping SAFe Enterprises identify better ways of working through the application, of Lean, Agile, and DevOps at scale and evolving SAFe guidance to support these goals. In addition, he fulfills the role of Framework Product Manager, ensuring that Scaled Agile has a clear vision, roadmap, and set of priorities for how the Framework will meet the needs of our customers.Andrew has successfully guided numerous organizations through SAFe transformations from across a wide range of industries, drawing on his many years of Lean and Agile experience. He previously led the Agile Services Practice across EMEA for CA Technologies (formerly Rally) and is a regular speaker at Agile conferences and contributor to the Agile community. He is a lifelong learner and recently completed research exploring how organizational structure impacts organizational performance.

As a methodologist and trainer, he has led numerous rollouts of SAFe, involving teams in North America, Europe, and Asia. He has trained over a thousand coaches and change agents whose key role is to help their organizations achieve higher productivity and quality by adopting scalable, Agile methods. As an early innovator, author, and proponent of SAFe, Alex returns this year to contribute to the latest version.
SAFe Fellow and Principal Contributor
Richard has 30 years of experience in software and systems development and has led large-scale Agile transformations for over 15 years. He is a SAFe Fellow and a Principal Contributor to SAFe. He is the co-author of SAFe® Distilled and the SAFe® Reference Guide and contributed to the SAFe® Lean Portfolio Management course, among others. Richard is a keynote speaker and has written several white papers on SAFe, Value Stream Management, and Technology Business Management.
The SAFe Fellow achievement is Scaled Agile’s most prestigious distinction, recognizing individuals who have exhibited the highest level of thought leadership and transformational expertise for implementing the Scaled Agile Framework. The SAFe Fellows program recognizes a select number of individuals with the depth and breadth of experience to work at the highest levels of complexity in enterprise transformation and strategy, and who have established themselves as thought leaders in Lean-Agile development. In addition, many have contributed—directly or indirectly—to core SAFe guidance and advanced topic articles. We are humbled and honored to work with these individuals to the benefit of all those who build and use the world’s most important systems.
SAFe COMMUNITY CONTRIBUTORS
In addition to the direct participation of the Methodologists and Fellows in developing SAFe content, there is an active community of SPCs and others who contribute to the IP that makes SAFe safe. One such forum is the Community Contributions section of this website. These contributors provide articles that interpret and extend SAFe based on their direct, personal, and specialized experiences. These articles are peer-reviewed, but the opinions expressed are those of the attributed authors.
Jon Feld, COO of The Feld Group
Eliminating the Blind Spot: A Proven Approach to Enterprise Technology Strategy Formulation
Agile Software Engineering courseware plus collaboration on team-level competency, testing, and quality articles.
The Scaled Agile Framework has been proven to deliver substantial business benefits in a large number of software and systems enterprises. We admire these companies for the courage to innovate, and we are indebted to them for the feedback they have provided. Specifically, we’d like to thank the many companies in our Customer Stories, each of whom has adopted the Framework and many of whom have provided specific input to help it evolve.
The contributors to Agile Software Requirements
Initial concepts behind the Framework were first documented in Scaling Software Agility, but the Framework per se was first documented in Agile Software Requirements: Lean Requirements for Teams, Programs, and the Enterprise (ASR), so it’s appropriate to repeat and update the book acknowledgments here. Thanks to the ASR reviewers, Gabor Gunyho, Robert Bogetti, Sarah Edrie, and Brad Jackson. Don Reinertsen provided permission to use elements of Principles of Product Development Flow. Thanks to my Finnish collaborators Juha-Markus Aalto, Maarit Laanti, Santeri Kangas, Gabor Gunyho, and Kuan Eeik Tan. Alistair Cockburn, Don Widrig, Mauricio Zamora, Pete Behrens, Jennifer Fawcett, and Alexander Yakyma contributed directly to book content.
A special acknowledgment to the Agile thought leaders
Of course, SAFe stands on the shoulders of many who came before us, particularly the Agile thought leaders who created the industry movement. It starts with the signers of the Agile Manifesto and continues with those outspoken thought leaders who have helped move the industry toward the new paradigm. The following have contributed most directly to our understanding of Agile development: Kent Beck, Alistair Cockburn, Ron Jeffries, Mike Cohn, David Anderson, Jeff Sutherland, Craig Larman, Ken Schwaber, Scott Ambler, and Mary and Tom Poppendieck. Others are acknowledged in the bibliography below.
A special acknowledgment to the Lean leaders
We are also fortunate to stand on the shoulders of Lean thought leaders, including Don Reinertsen, Jeffrey Liker, Gene Kim, Mik Kersten, Jez Humble, Eli Goldratt, Eric Ries, Jeff Gothelf, Josh Seiden, Henrik Kniberg, Dr. Alan Ward, Jim Sutton, Michael Kennedy, Dantar Oosterwal, Steve Womack, and Daniel Jones.
And to Edwards Deming
Finally, where would we be without the seminal works of W. Edwards Deming, to whom we perhaps owe the deepest gratitude of all? He was a visionary, whose tireless quest for the truth and unwavering belief in continual improvement led to a set of transformational theories and teachings that changed the way we think about quality, management, and leadership. The impact of his revolutionary ideas has been compared to those of Copernicus, Darwin, and Freud. Others have referred to him as the father of the third phase of the Industrial Revolution.
LEARN MORE about Edwards Deming at The Deming Institute.
SAFe is based on our own work, the work of the contributors and SPCs worldwide, and an incredible body of knowledge about Agile, Lean Thinking, Lean product development, systems thinking, organizational change management, human potential, business strategy, management philosophy, and more. Each of the books and articles in the bibliography below have contributed materially to the authors’ perspectives and are integral to what makes SAFe ‘safe.’
