Good Read: Cargo Cult Methodology

CIO.com has an excellent article Cargo Cult Methodology: How Agile Can Go Terribly, Terribly Wrong.
The essence of the article is adopting agile practices in an organization that is unwilling to adapt to the differences in agile methodologies, i.e., an organization that demands that a project forecast and write their requirements upfront isn't agile. Instead they are waterfall projects that take the guise of agile projects.
The success or failure of the project really has no bearing on the viability of agile methodologies, but the perception from the organization is that it does.
It's a good quick read.
