The "5 Whys" is a problem-solving technique used to identify the root cause of an issue by asking "why" multiple times. Developed by Taiichi Ohno as part of the Toyota Production System, this method encourages deeper thinking and helps teams uncover underlying problems rather than just addressing symptoms. Typically, the process involves asking "why" five times, although it can vary depending on the situation. Each answer forms the basis for the next question, leading to a more profound understanding of the issue. This technique is widely used in various fields, including manufacturing, healthcare, and business management.
