Answer: c. kaizen
In the Japanese language, the word “Kaizen” is closely associated with “constant improvement”. It is a business ideology that Japanese people use to describe a process of continuous improvement in business practices involving every person who works for the company. Kaizen is an ideology that tends to show that improvement — especially in productivity — is gradual and strategic. This concept relies on the idea that commitment and cooperation can improve the reputation of a business and does not rely on taking harsh measures to effect change.
