TRIZ, or "theory of inventive problem solving," is the next step in creating an organized and systematic approach to problem-solving. This approach looks at problems not as isolated incidents, but as part of a larger system. By taking this perspective, we can see that many problems can be solved by simply converting the harm into a benefit. For example, the heat generated by a car engine can be used to warm the passengers in the car. This simple conversion can make a big difference in comfort and safety. In many industries, waste is simply recycled and put to good use. This not only saves resources, but it also helps to create new products and jobs. If something does not work well, ask "where else would this limited effect be useful?"
