The best way to prioritise the questions is by uncertainty. An initial order for these three questions might then be:
- Can I make money from it?
- Can I get people to know about it?
- Can I build it?
A good read. I especially like the way it starts with a specific order of questions and reorders the questions based on uncertainty. I guess the order depends on who you are. If the startup has a marketing background the ordering may be different.
