Reverse brainstorming is a technique that combines traditional brainstorming with reversing the problem statement to generate more creative solutions. The document describes applying reverse brainstorming to problems faced by an insurance claims team. Instead of brainstorming how to solve issues like missing documents, the team asked how they could cause those problems. This generated 13 potential issues, which were then treated as problems to solve. The technique helped the team think more expansively about improving their claims process.
