Joke aside, that's basically the issue. "You're doing it wrong". Now there's various flavors of Agile, and one size doesn't fit all. But often, when people use "hybrids", instead of using the best of both worlds, they use the worse.
So we want sprints, but I can't just let my engineers work unchecked! So we'll have a full day planning meeting every 2 weeks, and a checkpoint meeting every week. The daily standups are going to last 45 minutes, and the PM will also have a 20 minute talk with each individual every day to see if anything changed during the day!
Now, I also want the full design documents and architecture up front, before the sprint start, lets have everyone sign off on it, and if anything changes, we'll just extend the sprint. /true story, happened at my last job...I quit a month and a half in.
Nothing is set in stone and each company has to figure out what will work for them...but virtually all the "hybrid methodologies" or pseudo-agile I've worked in only took the parts of Agile that suck, slapped in the worse parts of Waterfall on top, then wondered why it was a shit show.
