SAFe CREATOR AND CHIEF METHODOLOGIST
Recognized as one of the world’s foremost authorities on Lean-Agile best practices, Dean Leffingwell is an author, entrepreneur, and software development methodologist.
His two best-selling books, 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 practices and principles. Founder of several successful startups, including Requisite, Inc., makers of RequisitePro (acquired by Rational), 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). He currently serves as Chief Methodologist to Scaled Agile, Inc., which he co-founded in 2011.
SAFe CO-FOUNDER, FELLOW
Drew is a principal contributor to the Scaled Agile Framework, consultant, and instructor. Drew met Dean Leffingwell in early 2009 when he was developing a scaled Agile methodology for a management consulting company to bridge their strategic business framework with Agile. Since then, they have worked together with global clients to synchronize distributed teams using the Agile Release Train in the US, Europe, and India.
SAFe Methodologist, SAFe Fellow, and Principal Consultant

Clients include Intel, Elbit Systems, Cisco, Woolworths, Amdocs, and NCR.
Luke is a Principal Contributor to the Framework and the founder of Conteneo, (maker of Innovation Games®) which was acquired by Scaled Agile in 2019. The author of three books, Luke’s playfully diverse background of life experiences has uniquely prepared him to design and produce serious games to help professionals with strategic decision making. As a member of the Framework team, Luke is focused on Agile Product Delivery and is the product owner for the Agile Product and Solutions Management course. He is a regular presenter and keynote speaker at the SAFe Summit and Agile conferences around the world.

SAFe Fellow and Principal Consultant
Andrew has been supporting organizations with their Agile transformation for more than 10 years, drawing on his experiences from software development, project management, and product management. 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. As a member of the Framework team, he is focused on the Team and Technical Agility and Organizational Agility competencies. Currently, his postgraduate research includes exploring how organizational structure impacts the performance of the enterprise.
SAFe Fellow and Principal Consultant
Marc specializes in the Essential SAFe, Team and Technical Agility, and Agile Product Delivery areas of the framework. He is a former Scaled Agile partner and customer with a long history of leading enterprises through complex Agile and DevOps transformations. His experience in Lean-Agile software delivery spans more than 20 years and has included roles in development, architecture, operations, senior management, consulting, and business development.
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
We are also indebted to the many SAFe Program Consultants (SPCs) and others who are doing the serious work of applying the Framework in enterprises across all industries every day. Many have contributed indirectly in discussions, trainings, workshops, blogs, webinars, forums, etc. More specifically, the following individuals have directly provided content that is included in either the Framework primary knowledge base or in associated advanced topic 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. Even that list is not exhaustive; many others—Mike Cottmeyer, Ryan Shriver, Drew Jemilo, Chad Holdorf, Keith Black, John Bartholomew, Chris Chapman, Mike Cohn, Ryan Martens, Matthew Balchin, and Richard Lawrence—contributed words, thoughts, or encouragement.
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, Martin Fowler, Craig Larman, Ken Schwaber, Scott Ambler, and Mary and Tom Poppendieck. Still others are acknowledged in the bibliography below.
A special acknowledgment to the Lean leaders
A special acknowledgment to the Lean leaders In extending Agile to the enterprise and developing the broader Lean-Agile and DevOps movements. We are also fortunate to stand on the shoulders of Lean thought leaders as well, including Don Reinertsen, Jeffrey Liker, Gene Kim, 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.’
