Scott Ambler has put together a survey that shows surprisingly positive data regarding application of Agile in companies. Apparently, more than two thirds of respondents were already adopting Agile practices, and among them close to half were already on their second project, or even more. Success rates are also very high.
OK, this is no scientific data: participants had to go to Dr Dobb’s website, which probably tends to attract American developers, with at least some passing interest in their work. So certainly not too representative. Also, Mr Ambler seems a slightly controversial figure
Still, we are lacking data in the Agile world . This survey is akin to clinical trials: an encouraging result, though it does not prove definitely the effectiveness. Useful.
