The practitioner who wrote it down, then set it running.
Joshua Barnes is the founder of Process Mentors and the co-creator of End-to-End Flow, co-authoring the End-to-End Flow Series with Curtis Hibbs. He is the creator of e2e Flow, the value stream management product built as one continuous worked example: a single connected thread of value traced from a customer idea through strategic objectives, initiatives, value and innovation increments, features, stories, and tasks, used worldwide to make value delivery visible from ideation through consumable release.
For over two decades he has guided Fortune 100 companies, government agencies, and enterprises across financial services, healthcare, telecommunications, and retail: improving end-to-end value delivery flow, translating strategy into execution, and quantifying Cost of Delay. He has coached executives, trained thousands of practitioners, and guided hundreds of teams. He is a LinkedIn Learning author, an international keynote speaker and livestream host, and has served on the board of the Value Stream Management Consortium.
Methodology authorship is a habit, not an event.
Before End-to-End Flow, Joshua spent years at the center of the Disciplined Agile world, becoming one of its most recognized voices and co-creating Disciplined Agile Next, the framework’s evolution toward value acceleration. That era served organizations of size well, and what it taught is written into everything on this site: that frameworks succeed or fail at the level of daily instruments, that examples teach what abstractions cannot, and that a way of working nobody adopts is a shelf of binders.
End-to-End Flow, the Delivery OS, and the Increment Delivery Chain are where that road led: the practices proven over two decades, written down as one lifecycle, and set running under agentic skills.
