A companion repo for my talk at DDDBE on the 2026/05/12 called Domain Prototyping, before I knew of the existence of Tobias Goeschel's concept of Domain Prototyping.
Go check it out though, if I had to put it in my own words, Tobias describes a way of working that leverages the strengths of Clarity, Lean, Systems Thinking, and Domain Driven Design, to build malleable software that matters.
