Mike Beedle was an American theoretical physicist turned software engineer, and he was the author of the first book and earliest papers about Scrum. He was also a co-author and a signatory of the Agile Manifesto.
He debated that SAFe is not Agile, and he added that there are many other better alternatives. He articulated how SAFe in particular and the Agile Train Releases concept, violate all the values in the Agile Manifesto.
