It is sometime difficult to have an overview of the different principles and practices that are grouped under the Agile banner. In his blog post, Jerome Kehrli has tried the challenging exercise of classifying Agile principles and practices using the periodic table of chemical elements as an inspiration.
Jerome Kehrli has taken the principles and practices of XP, Scrum, Lean Startup, DevOps and others. He has then classified them using different perspective: their domain (architecture, software engineering, etc.), their level of maturity or complexity and if they are related more to the organization or the engineering. Around 60 principles and practices are placed according to these criteria. Each of these principles and practices is then explained in detail.
