Dmitry Vanitski, a Principal UX Designer at EPAM, wrote an article about Object-Oriented UX. It's a framework that helps you understand from which objects your UI will be built. And what connections between them. Used twice in my work, I think it's pretty helpful on stage when you need to gather requirements for a future project. https://medium.com/design-spot/объектно-ориентированное-про-ектирование-54c96b2bca03
