This is a technique that I've just thought of 2 hours ago and I'm not sure if it's employed by anyone else because I've read a lot of articles and chapters about creating characters and I've never seen anything like this. I'm trying to write a fantasy novel and of course the first thing you need is creating the characters. I already had like 4 or 5 I had in mind, but then creating ones beyond that small group, the supporting characters and minor ones, became quite tedious; listing out their hobbies, their everyday lives, what they do, history, etc. And then I remembered something I've read in a book how a characters true colours come out in the face of adversary. I thought, what if instead of listing out boring descriptions of the characters, you outright place them in a dire situation and ask yourself what they would do in that situation? Like for me, the character(s) are by themselves in the woods, and they see a stranger running away. Then they see a person with a knife chasing them, but the character has yet to be seen by both the victim and chaser. What would they do under those circumstances? And it's not just a two answer question if the character is going to save the stranger or not. But like would the character completely ignore the situation and continue hiding in the shadows? Would he think about it, but still hide in the shadows? Would he jump out without hesitation? Would he jump out, regret midway, and run like hell? And I could even twist it up; what would the character do if the victim saw the character? Would it change his decision? What if the man with the knife saw him? Would it also change his decision? I've already had a lot of fun with this and it's saved me a lot of time creating characters. I feel like everything else falls in place about their overall persona because in the face of adversary, you know what they are going to do.
