I find myself in a frustrating conversation when I talk about minimal viable products. A goodMVP is not viable and is certainly not a product, that's what the term is about. Chances are it isn't as small as you want it to be.
In the world of lean startups, founders have to figure out how to fail as fast as possible. If you fail, you end up with a functioning business. Trying to fail involves looking at your business opportunities and thinking about where you might fail in the future. Go and figure that out.
If the entire customer base is already happy with eBay, you can't build the world's best platform for selling Beanie Babies. If the scooter companies don't care if the scooters get stolen, then it's not a good idea to create a lock for them. It would be great if there was a way to know if anyone would buy your product before you write a single line of code.
So where do they come from? The smallest amount of work you can do to confirm or debunk your hypothesis is called an MVP. Eric Ries, the author of The Lean Startup, uses a particular example. It wasn't a full product, but it was full of features. A lot of features were not stripped away. The video showed how a product might work. If they build it, they will be able to find a customer base for their product. They built the product and made it a huge success.
How DropBox Started As A Minimal Viable Product
Thinking outside of the box is what a good MVP is. How much code can you write? Is it possible to get away with doing no design? If your biggest question is whether you can attract customers for a customer acquisition cost that makes sense, could you just run an advertising campaign and a check-out page, and then just refund whoever places an order? If you're worried about brand risk, could you create a fake brand and get an answer to your product?
The trick is to think carefully about the hypothesis, what needs to be true about your product, the market, the problem space you are entering, the customers you are hoping to attract and the competitive landscape. Are your assumptions correct? A really good question is what starts the design of a goodMVP. There are a few examples.
The key is to think carefully about what the question is, and then come up with elegant, low-lift ways of asking it. Could a survey work without shipping code? Could a video demo give you the answers you need? Can you call 50 customers and ask them questions to see if they suggest a solution to the problem? They might surprise you in two ways, one being that your customers may either overwhelmingly want what you're suggesting or they may hate it.
I don't have a suggestion for a better name for it, just don't fall into the trap of thinking of it as a product, being viable or simple. There are some things that are complex. To get an answer to your questions, you should spend as little of your resources as possible.
