Value Proposition Design
Who are your final customers? What are their needs, gains and pains? How you are going to address them? What services and pain reliever are you designing to offer?
Offering Experiment Design
Did you ever test your value proposition on a real use case? Do you have a prototype? Have you tested the offer adherence on your target market segments? Was the test conducted to real final users? How it was performed? Who performed the experiment design? Was it technical significant?
Was the product technology tested on larger customer groups? How the blockchain will scale?
