This is the area of software development I actively dislike. I've had interview questions about whether at work we practiced agile, or SCRUM or some other crap. I'd much rather work than relegate time to learning about the trendiest way to ship.
When I was in charge of development, it was simple. Ship as soon as it's ready as long as it's not a Friday, bugfixes go all the way to the top of the pile. I don't even know what scrum means. If it's dead, I'm glad I've heard the last of it.
