We need a new innovation infrastructure for the new industrial revolution. As startups disrupt every market, the software complexity crisis continues to kill the competitiveness of large organizations. Just as mastering mass production defined the winners and losers of the automotive landscape in the 20th century, mastering large-scale software delivery will define the economic landscape of the 21st. Unfortunately, technology leaders are woefully ill-equipped to solve the new problems posed by digital transformation: Despite breakthroughs such as Agile and DevOps, we are still burdened with decades old software architectures and technical debt. The smallest changes to complex systems require heroic efforts, making large-scale software delivery slower than ever. Something more is needed, because by definition, transformation must include every person, process and tool involved in software delivery. The value of solving this problem is truly immense -- it will elevate the productivity of every member of your IT staff by at least one order magnitude, dwarfing the productivity advantage created by the first automobile assembly lines. Solving this problem creates an infrastructure for innovation will enable every organization to win a portion of the $2.5 trillion that will be created annually through better software delivery. This book provides leaders the Flow Framework to create the technology equivalent of an assembly line, across thousands (or even tens of thousands) of IT professionals -- and enables optimizing value creation across your entire organization. The framework is based on two decades of research spanning almost every domain of software delivery. It builds on data collected from the value streams of hundreds of organizations and open source projects to give you a toolkit for delivering software at the pace of a startup. Rather than cars coming off the line, it will be new apps and features that delight your customer and drive revenue results.
