Agile software development processes are influenced by best practices in Japanese industry, particularly by lean development principles [12] implemented at companies like Toyota [13] and Honda [14],  and knowledge management strategies developed by Takeuchi and Nonaka [11], now at the Hitotsubashi Business School in Japan, and Peter Senge [15] at MIT.  Scrum is an Agile methodology that delivers software to customer and end users faster, better, and cooler [16, 17]. As the Chief Product Owner at Yahoo observed, coolness is a requirement at Google, Yahoo, and most software game companies. It must be highly suited to a creative approach to development of complex and innovative systems and it must scale. It is used on some of the world's largest projects at British Telecom and Siemens because of its high productivity with distributed and outsourced development teams. It is the only software development process that has repeatedly demonstrated linearly scalable productivity when adding resources to large projects [18, 19]. The most profitable software product ever created (Google Adwords [20]) is powered by Scrum and the most productive large project with over a million lines of code (SirsiDynix and Starsoft [18]) used a distributed, outsourced, Scrum implementation. CMMI Level 5 companies cut costs in half with Scrum while simultaneously improving quality, customer satisfaction, and the developer experience (Systematic Software Engineering [19]). At the same time, Scrum remains the process of choice in small entrepreneurial companies where it has it roots.
