A quality management system (QMS) is both necessary and good business in scientific manufacturing, clinical diagnostics, pharmaceuticals, and medical device facilities. In addition to controlling cost, these systems ensure that a safe, effective, and reliable product or service is offered to end-users. The International Standards Organization (ISO) publishes standards relating to research and manufacturing facilities. ISO 9001 covers current good manufacturing practices (cGMP) and the implementation of a QMS, whereas ISO 13485 covers QMS design and implementation for medical devices, including clinical diagnostics tests. Many pharmaceutical and clinical facilities also fall under the jurisdiction of the Food and Drug Administration (FDA), who inspect facilities globally to ensure compliance with their safety regulations. Quality control (QC) covers processes used in product development to verify that all design inputs and specifications are fulfilled. Quality assurance (QA) is the testing/batch sampling analysis that validates final product performance and intended use. When issues arise, experiments uncover root causes for corrective and preventive action. Standard operating procedures (SOPs) guide manufacturers with release criteria and maintaining retains to investigate performance issues. Analytical equipment used for QA/QC studies such as raw-material evaluation and stability testing include clean benches, balances, moisture analyzers, spectrophotometers and stability chambers.
