Take a look at the Scaled Agile Framework (SAFe):

It's an atrocity of an overbearing bureaucracy created by a committee of consultants that obviously fetishise process.
Take a look at the agile manifesto:
Its very first principle is:
> Individuals and interactions over processes and tools
Take a look at the rest of the principles and compare them to that diagram. SAFe is clearly the opposite of agile. It calls itself "Agile", but it's as non-agile as is possible to get.
What we have here is not the no-true-Scotsman fallacy, it's somebody rightfully pointing out that somebody born in Australia, who has never left the country, with no heritage that comes anywhere near the northern hemisphere, is not, in fact, Scottish.
This isn't true though.
