Less is more agile | Tales about Software Engineering

There is this view, I'll call it Agile Purist, that I find frustrating in software. There are more than a handful of folks, including some very smart people that I highly respect, who seem to believe the only thing we need to know to build great software is the Agile Manifesto. Frankly, I've never seen that be enough to organize anything more than a trivial size team creating a small number of things. It is a frustrating argument to get into too, since inevitably the purist will refute all your arguments to the contrary with "Your doing it wrong".

The Agile Manifesto was a good solution for the time but it misses a lot of dimensions. There were no marketing, sales, or customer teams writing that manifesto. There were also no operations people making sure stuff works 24 hours a day. There also weren't any women authoring the manifesto.
