• How do I design a Block chain app
• What does this solution need to let users do?
• Will the proposed solution reduce or remove the problems and pain points currently felt by users?
• What should this solution prevent users from doing?
• Do you need a solution ready for heavy use on day 1?
• Is your solution idea enhanced by the use of Block chain? Does the use of Block chain create a better end-user experience? If so, how?
• Has your business developed custom software solutions before?
• What level of support are you going to need?
• How big is the developer community?
• Does your vision of the future align with the project or platform’s vision of the future?
• Does the platform aim to make new and significant contributions to the development space, or is it an efficiency / cost play?
