Recently Andrea Tringo posted in Sun Alumni mailing list asking questions in every executive's mind who wants to adopt agile development methodology (like XP) but do not know how to proceed safely. Andrea asked: I know a lot of tech companies are enthusiastically adopting Agile, as many of us embrace(d) Six Sigma, among other practices.
