Here's a presentation I gave to some executives on the possibility of tokenizing invoices with ethereum and selling them on a DeFi market.
With any project, especially one that is net-new, it's good to understand the flow, how a user might engage, through what interface, and how it works.
I like to use a method akin to a service design blueprint that combines the flow with the front-stage action (user interface) as well as paired up with what is required to drive that functionality (back-stage action). Plus a notes section for riskiest assumptions and next action steps needed to be taken.
Let me know what you think.
