I ask myself "Will my idea solve a problem?Will it be helpful for the people?"
If the answer is YES,I calculate the budget for my project and I think about ways to fund my project(if my personal savings are not enough.My list is quite simple.
1.Funding solutions.(crowfunding,ICO,get a loan)
2.Hire a team of developers,marketers...Where to find the best ones?How much it will cost?
3.Creating your idea(all the costs involved-hosting,programming,design)
4.Advertising and marketing.Budget for promotion.What marketing chanells are we going to use?Audience targeting.Creating polls and surveys.Hope that this answers your question,OP.
