Chang Shin Indonesia is very focused on the quality of the products it creates. Problems found in PT. Chang Shin Indonesia, namely the reduction of a purchase decision or order from a customer, one of which causes employees to stay at home on Saturdays, which basically work normally on Saturdays as usual. Reduced orders greatly impact the company, especially on employees. One of the factors that affected the decline in orders was in terms of product quality. For example, many long threads are still attached to finished shoes and also the size label where there are many repairs, one of which is that the label does not match the tally sheet. This problem is often found in the sewing or stitching department.
