Inspection
Inspection involves a systematic examination of products, processes, or services to detect any deviations from defined quality standards. This procedure typically includes visual, physical, or functional evaluations to identify defects or non-conformities early in the production or service delivery process.
Testing
Testing is the practice of subjecting products or processes to predetermined conditions under controlled environments to verify that they meet quality requirements. It is a critical step in ensuring that performance, safety, and reliability standards are achieved before full-scale production or market release.
Statistical Process Control (SPC)
Statistical Process Control (SPC) is a quality control method that utilizes statistical techniques to monitor and manage production processes. By analyzing data from process outputs, SPC helps in identifying trends, detecting anomalies, and minimizing variations, which in turn reinforces consistent product quality.
Sampling
Sampling involves selecting a representative subset of items or occurrences from a larger batch to perform quality checks. This method is cost-effective and time-efficient and helps in making inferences about the overall quality of the production lot without inspecting every single item.
Quality Audits
Quality audits are systematic and independent evaluations of an organization's processes, procedures, and systems to ensure compliance with established standards and regulations. Audits help identify areas for improvement and assist in maintaining and enhancing quality control across operations.
Calibration of Equipment
Calibration of equipment is the process of verifying and adjusting the accuracy of measurement instruments used in quality control testing. This ensures that the measurements taken are reliable and accurate, which is fundamental for making informed quality decisions.
Corrective and Preventive Actions (CAPA)
Corrective and Preventive Actions (CAPA) are proactive strategies adopted to identify, correct, and prevent the recurrence of quality issues. Corrective actions address existing problems, while preventive actions focus on eliminating potential causes, thereby promoting continuous quality improvement.
