If you, just like us, ever found yourself confused by the number of agile methodologies and their hierarchy, then this post is exactly for you. We use the picture below as our cheat sheet and thought some of you would like it as well. So let us dive in!
As expected, at the core of it all we have the agile theory, representing the core values and the 12 principles defined in the manifesto. As you know, this theory in itself does not provide any specific rules, it simply reflects what the project management teams should strive for, such as improvement of the process, continuous delivery and others. Therefore we made sure to separate agile in the picture, so we would not forget and would not start to associate it with just one methodology.
Talking about the methodologies, these are the next part of the pictures. Listed closest to agile, we have the methodologies that were developed straight after the agile manifesto or adapted to fit its requirements. Here we find Agile Modeling, Adaptive software development (ASD), Agile Unified Process (AUP), Crystal Clear Methods, Dynamic systems development method (DSDM), Feature-driven development (FDD), Lean software development, Scaled Agile Framework (SAFe), Scrum and extreme programming (XP).
We consider these to be the first generation agile methodologies, because they were not influenced by or based on other agile methods. The second generation of methodologies is the exact opposite. Kanban, Scrum-ban, Large Scaled Scrum (LeSS), Disciplined Agile Delivery (DAD), Nexus, Enterprise scrum and Industrial Extreme Programming (IXP) were all created out of meshing other agile methods, or by trying to improve a single already existing method out there.
One more interesting thing about the second generation agile methods is that they are often used out of the traditional agile industry of software development and more often than not adopted to serve larger teams and even full corporations.
We hope this clears up your questions and invite you to share your cheat sheets or any possible additions to ours.
