And it's unlikely that more than a low 1s% of companies do agile as originally conceived. "Agile" has become everything it was originally opposed to: tons of process, specialized roles that have nothing to do with development (scrum masters), little to no direct communication with customers (at least in the places where I've worked). The dominant tool for doing "Agile" (Jira) says it all - a slow, heavy, bug tracking system with everything and the kitchen sink in terms of features often imposed on teams from the top down. Very "agile" indeed.

I can 100% guarantee you my SAFe company still thinks of themselves as Agile. Sure, we just planned out what were doing in every sprint for the next quarter, but we still do the ceremonies, and that's what's important, right?
