Quality costs are the all the costs that a manufacturer incurs to ensure it produces a quality product. Quality costs to prevent low-quality production costs and costs that arise after a low quality product is produced, so the cost of poor quality can cause rework, retesting, delay,and loosing money too.
I think the success of any medical device industry is contributed by different factors such as global market growth, technology innovation, financial investment, educated human resources, governmental initiatives (FDA), and QA/QC people.
QA professionals should make sure that the products meet FDA-current Good Manufacturing Practices (cGMP) and internal standards. They are also responsible for training, audits, documentation, and communication to leadership to prevent extra costs for poor Quality.
