On June 11th in San Francisco, at the offices of MindJet, we’re going to hold the first ever gathering of Agile Marketing practitioners, which we’re calling SprintZero. I’m super excited. One of our goals will be to put together an Agile Marketing Manifesto. In preparation for this, Travis Arnold posted a roundup of Agile Marketing Manifestos. Reading over Travis’s roundup, I’m struck by the role of the manifesto compared to the other elements that have made Agile Development such a success: the manifesto is the visible tip of the iceberg, but without the remainder of the iceberg, the principles and the methodologies of Agile Development, it would never have had such a big impact.
