With all due respect to Seth Godin, while he may be a marketing guru, his post about minimum viable product makes me think that he hasn’t participated in the product development process in a very long time, considering that his definition of minimum viable product is pretty coarse (and likely why it doesn’t work!).
As a product guy, minimum viable product is one important method with which to organize product development efforts, and to maximize the amount of benefit derived from scarce engineering, development, and management resources. In agile development circles, Product Owners work with the team to consciously choose to release “MVPs” frequently, or release a bunch of them together in an integrated package or manner. My take is that “minimum viable product” is the set of features that satisfy the core needs of your target champion audience and provides the team with the greatest return in both actionable feedback and revenue/revenue potential. More than one can go live at a time!
