Good beginnings are crucial to any project. There's one thing you can't evolve into a software product: the ability to evolve it. Lean Architecture is a treasure of practical advice on how to build a great architecture for any Agile application, building on Trygve Reenskaug's Data, Context and Interaction (DCI) paradigm.
