Quality control (QC) is a process by which a company seeks to guarantee that product quality is maintained or improved. It is designed to reduce inconsistencies and enhance the quality of the product. Quality control requires the establishment of an environment in which management and employees strive for excellence. To do this, staff are trained, reference points are created for product quality and the products are tested to see if there are statistically significant variations. Quality control is the ultimate goal of an efficient company.
Any product or service that is produced with a certain level of quality that a company seeks to achieve. Quality control methods help to standardize production and reactions to quality problems in various industries, from food production to automotive manufacturing. Quality control can be a rewarding profession if you enjoy working with people, communicating, presenting results and working to make products better and safer. Nowadays, with robotics present in all processes, quality control can be carried out entirely by robotics through artificial vision and analysis. Quality control is developed to improve the industrial atmosphere by increasing employee morale, which ensures cordial relations between the employer and the employee that lead to better understanding and closeness between them.
Quality control is part of quality assurance, which consists of programs and departments that guarantee high-level management, customers, and government inspectors that products meet all quality requirements and safety regulations. A common form of quality control chart is the X bar chart, in which the y-axis of the graph shows the degree to which the variance of the tested attribute is acceptable. Companies that have quality control methods usually have employees who pay close attention to their work. Usually, you start by being hired as a quality control or control associate after meeting educational and work experience requirements. Quality control can be done in many ways, from testing products, reviewing manufacturing processes and creating reference points.
By producing better quality products and meeting customer needs, quality control increases people's goodwill. Three examples of quality control could occur in the food industry: monitoring ingredient specifications, reviewing supplier lists and ensuring that the facilities where the food product is made are hygienic. In addition, to differentiate and establish a product in the market, quality is one of the most important parameters, so it is necessary to control it. Having quality control within a company helps ensure product quality and the overall success of a company. The company has adopted a total quality management system in which it adopts statistical methods of quality control and quality management to ensure that its products comply with all specified controls and procedures and are of the highest quality. Quality control plays an essential role in operations management as it helps businesses reduce inconsistencies and improve product quality.
It also helps companies differentiate themselves from their competitors by providing high-quality products that meet customer needs. Quality control also increases employee morale by creating an environment where management and employees strive for excellence. Finally, it helps companies ensure that their products meet all safety regulations.
