The 5 Whys technique is often associated with Sakichi Toyoda, the founder of Toyota Industries.
It was developed as part of the Toyota Production System (TPS), a system famous for its emphasis on continuous improvement.
While Toyota popularized the technique in manufacturing, similar problem-solving methods have been used across various industries.
The concept is simple: when faced with a problem, you ask "why" it occurred, and then continue asking "why" to each subsequent answer, ideally five times or until you reach a fundamental cause.
This process continues until you identify the fundamental cause.
