I think this is often where people are confused by MVP. Your minimum viable product isn't (necessarily) your initial product. It's the product you build to test a hypothesis.
This is why the article read fairly false to me, not that there wasn't the odd nugget of value, but coming up with a new MVT, is just adding to the confusion.
I quoted directly from the article. MVP is built after the hypothesis testing, but it’s still a test, a test of the independent hypotheses combined into a material product.
“Build an initial product to bring all of your insights together and test them with your target customer.”
Yeah, that initial product is the MVP.
