I agree with most of the people here, Quality can definitely be demanding for medical and pharmaceutical companies out there. It is the most important core factor in the high cost of delivering good quality products to the consumers. In an industry, when changes are to be made to any product, then the roles of quality assurance, quality engineer, and regulatory compliance are approached. Their roles are to monitor any engineering change controls on a product which eventually enhance the quality of the product. However, while making the changes, their roles also includes to not interrupt the result of a product in the manufacturing department. Ensuring this and making a quality product can be burdensome and difficult for the company as it takes away the available resources from another task. On the other hand, it is an efficient process that will deliver a good and quality product and not risking company for delivering a product that needs work to be done.
