Agile Methods and especially Scrum has been gaining a lot of popularity over the last few years and is now considered to be a mainstream methodology, where many IT-projects look to use these methods to deliver faster, better and cheaper. Still Agile Methods are not fully accepted as a methodology in large projects, which tend to take favour of traditional methods as the Waterfall Model or Rational Unified Process (RUP). This presentation focuses on how to scale Scrum to fit large projects and what Scrum principles you should keep holy and which you can sacrifice. http://javazone.no/incogito/session/Smidige+metoder+-+store+prosjekter.html
