Explain how improving quality can lead to reduced costs

Improving quality of a product can lead to a lower cost since if products are faulty, the customers will return which is sometimes need to be replace thus it would be a profit loss but if it is of good quality this can be avoided. Another would be if there is no warranty in the shop it can damage the reputation causing them to lost customers and can also result to lawsuits. If there is good quality then these can't be happening.
