Kaoru Ishikawa (1915 - 1989)
• born in Tokio 1915
• graduated University of Tokyo in 1939 with an
Engineering degree in applied chemistry
• worked as a naval technical officer until 1941
• worked for Nissan Liquid Fuel Company
• associate professor at the University of Tokyo in 1947
• famous person in Qualitymanagement
• not only product quality
• but also e.g. quality of Management and assistant
• developed several quality-tools
• One of these tools is the Ishikawa-Diagram(also called Fishbone- or cause and effect diagram)

basic conceptThe Idea:
think about possible causes and reasons leading to an effect or a problem
find solution for preventing those problems

basic concept• one problem/effect
• 7 causes lead to the problem/effect
• the causes are divided into main- and sidecauses
The 7 causes are:
1. Methods
2. Machinery
3. Management
4. Materials
5. Manpower
6. Environment
7. Measurement
