Is it me, or is "a series of small waterfalls" like TFA describes not actually anything to do with Agile? I mean, I guess it's more agile than one big waterfall, but it's still not embracing the principles of Agile (like involving developers in product decisions, or letting developers assign deadlines). It's still locked in the worldview of "serious people spec the product, then the nerds push the nerdbuttons to build it".
