My current focus is scaling lean and agile methods for a single product group of 200 to 2000 people (Asia, Europe & NA—usually multisite including offshore), and large (10,000+ people) enterprise transformations to lean and agile methods. Collecting these as Large-Scale Scrum. Much of my work is in large embedded systems (telecomm, control systems, printers, ...), investment banking, and energy and exploration industries.
videos of QConkeynote and interview, on very large scale product development with Scrum.
After my QCon keynote in London, wrote a short InfoQ article on practices for scaling agile design, that includes a free download of the Design & Architecture chapter from our Practices for Scaling book
