Why would anyone take something seriously that was created and peddled by consulting outfits at $700-per-hour bill rates? I had the misfortune of being incarcerated at Pivotal Labs for a month by a misguided boss who thought their bizarre religion was the answer to all of life's ills. Boy, was that eye-opening.
As many people rightly point out, that doesn't mean we can't pick up some new ideas from it - my company now does short daily meetings and have a chart with everyone's daily tasking on it, and those have proven very effective. But the other 99% of what the Snowbird 17 vomited forth upon our industry is empty zealotry and jingoism. It was like Scientology right in our codebases, and worked about as well. And no, for god's sake, it wasn't because we just weren't doing it well enough.
We do have shockingly dramatic quality issues in the software industry, but they will never be addressed by the next dumb-ass management fad. We need to sit down and re-think the ways that we learn to code, get serious about "Software Engineering" degrees in our colleges, and let go of fetishized code patterns as the primary unit of engineering ability. In my own experience, we know plenty enough design patterns, but almost no one understands how to exercise coding judgment in the context of a team or long-term project.
