Brainstorming is a group process used to generate ideas without criticism, where all participants contribute ideas on a given topic. It is meant to spur creativity rather than make decisions. Properly facilitated brainstorming leads to more creative ideas, involvement from all participants, and buy-in for the process. The document provides guidance on preparing for and conducting a brainstorming session, including deciding the topic, notifying participants, gathering materials, setting ground rules, recording all ideas generated, and following up after the session.
