Oh, man, you haven't seen Jira driven disorganized waterfall until you've seen SAFe -- Scaled Agile Framework. Basically Agile with cement shoes, for organizations that are scared to do anything without getting it countersigned in triplicate.
I love how there is an ongoing war between "the old guards" of agile and SAFe. Look up some of the rants, it's a great read. Certificate peddlers flaming each other.
SAFe has a great, telling name though - it's designed to be safe for corporate control freaks. They might not know waterfall, they just live it in their guts.
Easy to identify, they believe in being a "visionary leader" and "inspiring the lower rank".
