I suffered many years developing software with the waterfall methodology, until a great manager convinced us that Agile was the cure for our suffering. It was not an easy sell for him, because many of us were too used to waterfall to believe that the problems were in the process, not in us, but after doing just one project with Agile we saw the light! NO way back!
