Smells like Agile in 2002:
Your DevOps efforts will probably fail unless your entire management team buys into the required changes, and executives recognize that they’re going to have to change the way they operate, as well.
Have fun storming the castle.
Anecdotally, I hear fun tales of BigCo’s being befuddled by all the changes needed here. It shows why it’s vital to prove to The Business side that it’s worth it, which is always tough for such dramatic changes.
