Totally agree, the other illustration where MVP supposedly only concerns functionality is not how I, or we in my company, ever define MVP. We use the other one to explain MVP to our customers. How can a 'product' be viable with only functionality? In my personal observation, working in a cross functional team which includes frontend and backend developers, and ui/ux designers, an MVP only consisting of functionality just wouldn't be considered. Perhaps the author is used to environments where those disciplines are siloed.
