@mickc79 Capital One, several government agencies, Time Warner Cable, Home Depot, Allstate, Microsoft, Google, Twitter, Tesla, Honeywell, the list is quite long. Lean principles apply quite nicely to most software projects, and big enterprises such as those listed may not be 100% lean, but there are absolutely teams within the org that operate following these principles. Also, can't forget Toyota, the granddaddy of the lean movement with the Toyota Production System.
@alentodorov basically where a bunch of suits sit in an office for 6 months building what they think a product should be, which is then handed to developers who have no say in what happens or how it should be built.
@mickc79: GE, Intuit, Humana, American Family Insurance, ING, AIA. These are the big ones that have integrated the Lean Startup process to the point of having a program with playbooks, dedicated trainings, etc.
