Ishikawa (Kaoru Ishikawa)

Kaoru Ishikawa was a Japanese quality control expert known for developing the fishbone diagram, also called the Ishikawa diagram. This tool helps identify root causes of problems by visually mapping out all potential contributing factors, such as methods, materials, equipment, and personnel. It promotes teamwork and thorough analysis, guiding organizations to address issues effectively and improve processes. Ishikawa's work emphasizes that quality improvement is a collective effort, and his methods are widely used in industries aiming for continuous quality enhancement.
