The "5 Whys" is a problem-solving technique used to identify the root cause of an issue by asking "why" five times. This method encourages deeper thinking and helps teams move beyond symptoms to uncover underlying problems. It is commonly used in quality improvement and process management. Developed by Taiichi Ohno as part of the Toyota Production System, the technique is simple and effective. By systematically questioning the reasons behind a problem, organizations can implement more effective solutions and prevent recurrence. This approach fosters a culture of continuous improvement and accountability.
