TRIZ, or "theory of inventive problem solving", is a Russian acronym that roughly translates to "the next evolutionary step in creating an organized and systematic approach to problem-solving." The theory was developed by Soviet engineer Genrich Altshuller in the 1940s, and has since been adopted by organizations around the world as a tool for improving creativity and innovation. One of the key concepts of TRIZ is the principle of periodic action, which posits that pulsed energy can be more effective than continuous force. This principle has been applied in a variety of ways, from the development of hammer drills to the invention of rear cycle lamps that flash instead of staying constantly lit. As organizations continue to face ever-changing challenges, it's likely that the principle of periodic action will continue to be a valuable tool for problem-solving.
