Robert Kerner, vice-president at New York Stock Exchange (NYSE), said that business needs change and software development needs to change along with them. One way that NYSE has become more agile has been to turn to open source technologies including PHP and the popular Drupal content management system.
Kerner said that the NYSE keeps developers agile by having them run code sprints that last for two weeks.
Building software in a waterfall approach where there is a big milestone release at the end of the process, isn’t conducive to success in the modern world, according to top executives from the NYSE and GE.
Speaking at the Zendcon PHP developers conference, Kerner told developers in no uncertain terms, that the waterfall approach doesn’t work.
