Quality controls are an aspect of quality management which focuses on the monitoring and assessment of product or service quality throughout a business's various processes. Quality control is concerned with monitoring and maintaining the quality of finished products and service standards, in order to ensure that they meet customer needs and expectations. Quality control is an essential part of an organisation's overall quality management system, and it involves determining what standards the product needs to achieve, and then carrying out the inspection and tests to make sure that the product meets these standards.
Quality control begins with the design phase of product development, where quality is first and foremost. During the design phase, quality goals are set for the process and production of the product. It is important that quality control is considered throughout the design process and that standards are set for the product before it is even produced. This ensures that the finished product meets the customer's needs and is of a high standard.
Once product design is complete, quality control shifts to the production phase. This is where the product is actually made and where quality control is vitally important. All materials and processes must meet quality standards in order for the product to reach the desired quality level. This can be achieved through the use of quality control techniques such as design of experiments, inspection and testing, statistical process control, and product testing.
Design of experiments is a technique which is used to test different variables during the design process, to determine how they affect the quality of the product. This allows the company to identify any problems with the design and make changes to ensure that the finished product meets the required quality standards.

Inspection and testing is another important part of quality control during the production process. This involves examining the product, performing tests, and evaluating the results in order to ensure that the product meets quality standards. This can be done through visual checkups and smoke testing, or through the use of more complex testing methods such as vibration testing, ultrasonic testing, thermal imaging, and x-ray analysis. Each type of inspection or test has its own set of guidelines and best practices that must be followed in order for the tests to be accurate and reliable.
Statistical process control, or SPC, is a method used to monitor the process of production in order to identify any areas of improvement. This involves collecting data during the production process and then analyzing it to determine if any changes in production are needed in order to produce a higher quality product.
Product testing is another aspect of quality control and it involves assessing the quality of the product before it leaves the production line. This can be done through laboratory testing, or by testing the product in an actual simulated environment in order to ensure that the product is able to meet the desired quality standards.
Quality control is an essential part of an organisation's success, and it is essential that quality control is taken seriously throughout the design, production, and testing stages. Quality control techniques such as design of experiments, inspection and testing, and product testing should be utilised in order to ensure that quality standards are met and that the customer is provided with a high-quality product or service. Proper adherence to quality control guidelines and best practices will ensure that product quality is consistent and reliable.
