"Agile" is a very vague and shapeless idea which is hard to design an experiment for; but I would settle for clean experiments with well-defined methodologies/frameworks/strategies/whatever. Specifically, for scrum or kanban. Whenever people talk about these two, they seem to misunderstand them more often than not.
