It seems really simple, right? But those of you who have been in entrepreneurship long enough will know that introducing a new product is a scary venture to say the least.
I think that Johnson's quote was rock solid. So many times we want to push out a product that really has no significant difference to the end user at all. We may introduce a new interface, or a new look and feel, but a product will only succeed if there is a demonstrable difference to the client.
If you want to figure out whether you should introduce a product to market, test your market. Show your product to the end users you will be marketing to. Do they say any of the following?
1. That is exactly what I need.
2. Finally I won't have to do x and y to get z.
3. Now I'll be able to x because of your product.
If any of these can be said about someone else's product, chances are you need to rethink your plan. And worse, if none of these statements are made by your test market, then you need to rethink your solution.
