Reinertsen's keynote presentation at GOTO Copenhagen 2012, titled "The Science Behind Lean Product Development." One of his most visible and widely circulated conference presentations, publicly available online and frequently referenced by practitioners encountering his work for the first time.
The talk serves as a condensed introduction to the core arguments of principles-of-product-development-flow: the mathematical foundations of lean practices, the cost-of-delay framework, queueing-theory-applied to product development, batch-size-reduction, and the critique of first-generation lean for missing the economic reasoning behind Toyota's tools. The "science" framing is characteristic — Reinertsen consistently positions his work as grounding intuitive lean practices in verifiable mathematical and economic logic.
The GOTO conference audience (software developers and technical leads) made this a significant vector for Reinertsen's ideas reaching the software community directly, rather than through the Poppendiecks or agile consultants. Practitioners in the audience who had not read principles-of-product-development-flow could encounter the core framework in accessible form. The talk covers the twelve-cardinal-sins framework and the economic-framework-for-prioritization in enough depth to convey the main argument.
The presentation complements the 2012 HBR articles — six-myths-of-product-development and wrong-lessons-from-manufacturing — that Reinertsen and stefan-thomke published the same year, making 2012 a high-water mark for Reinertsen's public visibility.
