The most common definition of Quality to date comes from the Japanese word, Kaizen, meaning continuous improvement.
The concept was shaped by Toyota Motor’s history of lean manufacturing and total quality management system, which aims to constantly find ways to improve and obtain zero defects. Kaizen is a way of life at Toyota.
Techniques for continuous improvement include: eliminating waste of time, mistakes and transport; eliminating fear of workers to report problems to their supervisors; the elimination of mistakes from the root of the cause; creating a relationship of satisfaction between customers who receive the product or service with their providers; creating long-term solutions through intellectual and mathematical rationalization rather than quick, short-term solutions.
Today, Toyota’s slogan is «75 Years of TOYOTA – Ever Better Cars». That «ever better» pertains to the concept of kaizen.
