What is the Quality Loss Function?

The Quality Loss Function, developed by Genichi Taguchi, quantifies the financial loss caused by deviations from the ideal (target) value. It is used in quality control to measure the impact of variability on product performance and customer satisfaction.

Why is the Quality Loss Function Important?

The Quality Loss Function is essential for:

• Quality Control: Identifying the cost of deviations from the target value.
• Process Optimization: Minimizing variability to reduce financial losses.
• Customer Satisfaction: Ensuring products meet customer expectations by staying close to the target value.
