What are the different types of quality control methods?
Quality control, or QC, is a set of practices established by many types of companies, although they can be most common in production companies. By creating a program of quality control methods, the company hopes to ensure that products and procedures are safe, consistent and efficiently managed. There are many different quality control methods, including random checks, mutual evaluation and mapping.
Many experts suggest that the best quality control methods use systems that require routine examination and control built into everyday work. Permanent quality control control can be recorded and solved faster. Those who rely solely on occasional quality controls or reviews can find themselves in serious problems if the problem requires a download that might require the exchange of thousands or millions of products. Some experts recommend employee training in QC from Peer Review to be built up consistent quality examination directly into the job description, although not distantACTING Workers from their primary tasks.
Random testing is a commonly used quality control practice. This includes a random selection of the product and submitted to strict tests to make sure it is on the standard. The theory for random checks is that the pre -selected product can cause a change in normal production routine that could create a sample that would testify to general quality. By using the random selection process, a general quality feeling can be obtained.
Charting is one of the most commonly used quality control methods. It includes the use of product samples to create graphs that report the product characteristics compared to the required standard. The use of mapping allows quality control staff to see how the process is controlled over time, compared to the ideal. For example, for measurement, if the nails produced have heads of consistent diameter, can be created a chart thatThe rice examines 20 random samples during the day of production to see how close or how far they can be from the required average. High levels of variations found by mapping may indicate a process that is not well controlled.
Some quality control methods revolve around training and involvement of workers in the QC process. A well -trained worker can not only be likely to make fewer mistakes, but can also be more likely to notice QC problems when they occur. In addition, if it actively supports the inputs and feedback on employees in quality related to quality, workers may feel more comfortable to bring proposals or noticed problems on control. Methods of quality control can be more efficiently by training workforce.
