A lot of processes, overall, are called Agile just for the sake of marketing. But concerning the way in which they operate, would you say that Waterfall is still the most used method nowadays (just masked as Agile most of the times)?
A few teams somehow come together and produce working products that succeed. Most teams don’t. What you call the method doesn’t matter much, because team and interpersonal dynamics drive development success and failure far more than technical skills and tools or management structure and planning.
