Remember the mid 90s (or not) with the so called PoC Products where you would create a minimum viable product? Well many of those PoC are still around in production (about a third of all barcode Point of sales as an example)and others are responsible for some of huge IT disasters (usually as they were used for everything as they worked great for a small area). while again others created untold black holes of disintegration. Like TNT MVP are neither new nor they are good or bad, but in the wrong hands they can be dangerous, while in good hands they are very useful.
The area where they are useful are low interfaced isolated systems that only create one extract and one import. All other complex systems is where the minus is not viable. However many PM do not understand this and that is why you should not give TNT or MVP in the hand of non technical managers.
The other argument about doing a job proper and as such not using MVP actually really went out of the window in the 90s and is not worth to rehash.
