Sometimes, while gathering business requirements, it is critical to listen to the subject matter expert's idea to solve a specific business problem. Brainstorming is the process of subject matter experts contributing their ideas to solve a specific business issue, problem, or requirement. During brainstorming, people can express their ideas about the topics, without any hesitation. We can use brainstorming for one or more topics and prepare ideas for the solution. Different ideas can be prioritized depending on the discussion with the group and, finally, we can come to a conclusion by selecting the best-suited solution for the business.
