Summary: The MVP is a double-edged sword in that it focuses your engineering and product management priorities, but might steamroll user priorities. An MVP that misses 'desirable' will risk the unintended consequence of poor user adoption. Instead, MVP's should focus on what constitutes priority, need, and desire from an understanding of user context, behavior, and scenario.
Where MVP went wrong
The MVP concept comes from the Lean Startup (book by Eric Ries). Ries emphasized meeting user needs and failing fast. For Ries, this meant quick prototypes and rapid user testing. Unfortunately, like many Silicon Valley UX teams (and authors), his definition excludes the important user needs discovery process that is part of the ISO and industry-standard Human-centered Design method.
