Quality is one key parameter that can determine the success of a fashion brand and this is the key selling point of many luxury fashion brands. Global competition in apparel manufacturing has also pushed manufactures to make sure they supply high quality products that are defect free. But it is inevitable that defects do occur in production especially in apparel manufacturing where one product passes through many hands before it is dispatched. Some of these defects result in what is commonly referred to as reworks and some end up being downgraded. Reworks negatively affect the overall efficiency of apparel production lines leading to increased decline in profits and loss of customers. Five apparel manufacturing companies were purposively sampled to find the common types and causes of reworks. In depth interviews were done with the quality representatives in the five companies and on site observations were made at the reworks station. The results show that reworks are mainly caused by sewing and seaming defects. There is absence of clear documentation on how a defect is handled in almost all the companies leaving the decision to in-line inspectors to decide. The study revealed that employees lack training on handling of reworks thus calling for the need to improve their quality control process so that reworks can be reduced. To effectively manage quality and mitigate reworks, it is essential to identify and implement key quality management factors tailored to the unique challenges posed by globalization in textile-apparel supply chains. Addressing quality in apparel manufacturing not only enhances product perception but also serves as a competitive advantage in a global market as it impacts sustainability. In conclusion the model suggested in the study can be used by the apparel manufacturing companies to improve their operations.
