START WITH A QUESTION
How do you start?
Well, like any story. I don't want to wirite about a topic. I want to answer a question. Start with a question and then find the data that will help you answer it.
How does it compare to elsewhere?
Be prepared that your question may not be answerable. You may have to pivot, or try a different question. Be flexible.
Places to start:
Folo old stories
Steal ideas from other news orgs. (IRE)
Is x doing its job?
