What is Quality Control (QC), and why does it matter?
A business uses quality control (QC) to maintain or improve the product’s quality. The company must create an environment in which employees and management strive to achieve perfection. It is achieved by training employees, creating benchmarks to measure product quality, and testing the products for statistically important variations.
The establishment of well-defined control is a significant aspect of quality assurance. These controls standardize production as well as the response to quality problems. By limiting the room for error, you can reduce the risk of employees being involved in production tasks they are not trained for.
Why is QC Needed?
It is expensive, time-consuming, and dangerous to create a product without proper controls. A company that sells defective products could also be held responsible for any injuries or problems caused by the products. Inspectors of quality control ensure that unsafe or defective products are identified and corrected.
How is QC Done?
In general, quality testing is completed at each stage of manufacturing or business processes. Employees will often start by testing the raw materials before pulling samples from the production line and testing the final product. The testing at different stages of production helps to identify the problem and what remedial measures are needed.
Quality testing in a non-manufacturing company can include customer service evaluations or surveys. It may also involve inspections or audits. Any process or method can be used by a business to ensure that the end product or service is safe, legal, and meets customer needs.
QC is Different by Industry
Quality control in business depends on both the product and the industry. In the food and drug industry, for example, quality control involves ensuring that the product will not make the consumer sick. To do this, the company tests samples taken from the production line using chemical and microbiological methods.
Quality control and assurance are of paramount importance in aircraft manufacturing. To prove that all phases and items of a build are completed according to strict standards, manufacturers must document, track and inspect them.
Quality control in automobile manufacturing focuses on parts that meet specifications and tolerances. QC is responsible for ensuring that engines, drivetrains, and mechanical parts work smoothly, efficiently, and safely. Quality testing in electronics may involve the use of meters to measure electricity flow and stress tests.
