Weirdest co-worker? I met this one guy who preferred waterfall to agile development...

yeah, I work with a lot of weird people like that.

I know a lot of people like that. One guy in particular swore things were faster using waterfall. When I asked him what his definition of waterfall was, he described it as gathering requirements on a feature and working through the feature over the course of the next few weeks then presenting the work to the stakeholders and then gathering more requirements and doing it again...I just shook my head...

Well... waterfall is not a bad thing and is better than agile under lots of circumstances. It really comes down to what you are developing.

Agile is a buzzword. But not all development should be agile!
