A quality control system (QCS) is a set of procedures that are performed to ensure that a manufactured product or service adheres to a defined set of quality criteria or meets the requirements of the client or customer. It is crucial for a manufacturer to have an adequate quality control system because it minimize errors, ensures consistency in product quality, enhances customer satisfaction, and helps the organization maintain compliance with industry standards and regulatory requirements.
Quality control (QC) focuses on the identification and correction of defects in finished products, while quality assurance (QA) is aimed at preventing defects through planned and systematic activities. Both are essential to comprehensive quality management.
Statistical process control (SPC) is a methodology applied to quality control activities that employs statistical methods to monitor and control a process. The aim of SPC is to ensure that a process operates at its fullest potential to produce conforming products with the least amount of waste (i.e., rework or scrap).
Inspections are a critical aspect of quality control, involving the examination of a product or service to ensure it meets the specified requirements. Regular inspections help catch defects early, before products reach the customer.
ISO 9001 is an international standard that specifies requirements for a quality management system (QMS). Aligning with the globally recognized ISO 9001 standard enables organizations to consistently meet customer and other stakeholder needs within statutory and regulatory requirements related to a product or service, providing a framework to integrate proven principles of quality control throughout the QMS.
Technology plays a key role by providing sophisticated tools such as automated inspection systems, real-time quality data collection, and analysis software that enhance the accuracy and efficiency of quality control processes.
