This article aims to provide a literature review regarding the application of QFD in improving product quality in food companies as well as providing contextual knowledge as an effort to implement QFD to improve product quality. The method used in this research is a systematic literature review. The results of the literature review analyzed show that QFD is proven to have an influence on the process of improving the quality of a product or company.
