Minimum Viable Secure Product, Minimum Viable Marketable Product, Minimum Viable Sellable Product.
I don't get it. Why do we need all these additions? Perhaps it is me who does not understand the meaning of "Viable". MVP is not a restricted, well-defined end-goal. "Viable" means viable for your case. You can fill in whatever you want. It does not mean "Viable" without security or "Viable" without "Marketability".
