Every organization claims to value problem-solving. Job postings ask for it. Performance reviews rate it. Training programs promise to teach it. Yet in most companies, the actual practice of problem-solving remains remarkably shallow. People jump to solutions before understanding the problem. They collect data to justify decisions already made. They fix symptoms while root causes continue to generate new failures. And when a solution works in one department, the knowledge rarely spreads to anoth
