Agile is an idea, over the past ten to fifteen years it has been turned into a process complete with certifications. That difference captures the essence of the difference between working in a corporate environment and working in a startup environment - and I've worked in both environments. The "suits" like processes, methodologies, and certifications. Startups, especially self-funded startups, have to get results otherwise they can't make money. As negative as Corporate Agile may sound, it's a far cry better than what they were doing before.

Bottom line? "McKinsey Agile" isn't intended for startups and small organizations or large organizations whose product is tech.
