I am trying to improve my brainstorming skills - to be more structured and be able to come up with ideas instantly. Under time pressure I have a tendency of coming up with random ideas instead of using an issue tree to brainstorm instantly.
I'm wondering what resources / approaches to practice brainstorming are suggested? Ideally, there would be (1) different types of brainstorming questions categorized (2) reference answers (3) good to have - a timer to limit time to think.
I'm already using cases as material, but I feel it is not efficient enough as I am planning to do “drills” specifically for brainstorming.
Thanks for any suggestions!
