The company I work for are on the verge of introducing the agile project methodology to our coding process.

Having read Steve Yegge's Good Agile, Bad Agile - http://steve-yegge.blogspot.com/2006/09/good-agile-bad-agile_27.html - I am somewhat skeptical about it being anything more than an unnecessary fad.

What are HNer's experiences with agile and would you recommend/advise against it?

UPDATE: Changed title to something less black and white :-)
