Quality control is a procedure used to ensure compliance with predefined quality criteria.
Quality assurance is the process by which companies ensure that the quality of their products and services is consistently high and that customer requirements are met. In addition to customers, this also applies to employees and suppliers.
Quality assurance comprises organizational and technical measures that are used to maintain the consistency of processes used to produce products or provide services. As a rule, these are all processes that are part of the value chain.The organizational tasks essentially include
The technical tasks essentially include
The aim of quality assurance is to identify influences that could potentially affect the quality of an end product in good time and to eliminate them. In this way, quality assurance ensures that quality management specifications are adhered to and implemented.
ISO 9001 is the standard most frequently used in quality management. It regulates the minimum requirements for a quality management system. Companies must implement these in order to meet the requirements of customers and the quality of products and services. The aim of ISO 9001 is to optimize processes and thus ensure their safety. It is therefore the basis for functioning quality assurance.
The main types of quality assurance are statistical and dynamic quality assurance.
Static quality assurance stipulates that defined quality parameters, which serve to describe processes and products, may fluctuate within a defined range. Statistical (Statistical Process Control) and computer-aided procedures (Computer-Aided Quality) and external auditors check whether the parameters are being adhered to. The resulting audit reports formulate the need for action. Companies can use this method to prove to the outside world that the minimum quality assurance requirements in the quality area in question are being reliably met.
In the dynamic type, quality assurance follows an optimization cycle. Actual conditions are recorded and evaluated and compared with target conditions. These values are based on measured values obtained on the basis of statistical procedures or customer surveys. If deviations are identified, measures for improvement must be taken as part of quality assurance (often in the form of a balanced scorecard).
There are also numerous methods for quality assurance. The best known include
A defect card enables attributive testing, but only the number of defects can be evaluated. It provides valuable insights for optimizing production processes in the long term.
Documentation can also be important in quality assurance. Documented, planned and implemented procedures make it possible to determine how processes run. They are thus measurable.
In quality assurance, audits are used to check various parties, such as suppliers but also the company itself, for compliance with standards. A high level of conformity to standards can ensure that products and services are of a higher quality.
These two methods ensure that measuring systems and test equipment are suitable and that measurements can be carried out without external influence.
The methods mentioned analyze the possibility of errors occurring or whether they occur. Processes can then be adapted accordingly to avoid these errors.
An 8D report stands for eight disciplines or process steps that are run through between the supplier and customer when a complaint arises. The 8D report is exchanged as a document. 8D reports make it possible to investigate problems schematically according to the PDCA cycle (Plan, Do, Act, Check; concept to continuously improve processes) and find suitable solutions. Troubleshooting is thus carried out with:
Quality management describes all measures that serve to ensure the minimum quality of products and services.
Quality assurance is process-related and deals with the planning of test mechanisms such as test concepts, test and measurement systems across the entire value chain or the entire manufacturing process. Quality assurance is therefore a phase of quality management
Quality control is also a part of quality management. In contrast to quality assurance, however, it is product-related. Its aim is to ensure the quality of a finished product by means of specific testing mechanisms. Quality control therefore comes into play at the end of the manufacturing process, whereas quality assurance is used as a preventative measure.
