Conduct Product Tests and Assessment
The main duty of a quality control specialist is testing and assessing products, usually in an industrial or warehouse setting. The quality control specialist may test parts or products using a variety of techniques, checking that specifications are met and that the product works as intended.
Identify Product Defects
A quality control specialist is ultimately responsible for identifying product defects or potential issues and determining what to do to resolve the issue. This may mean sending the product back through certain stages of the manufacturing process or pulling a product entirely if it does not meet expected standards of quality. The quality control specialist analyzes the results of lab or usability tests to identify these defects and make sure they do not persist.
Record and Report Issues
The quality control specialist also keeps detailed records of product defects or manufacturing issues as they test and assess products. These detailed records can help identify and eliminate recurring problems and also provide a paper trail to aid in accountability and error reporting. The quality control specialist may provide these reports to supervisors or plant managers to help them make decisions about manufacturing processes and practices.
Support Process Improvements
Quality control specialists are also responsible for supporting process improvements throughout the testing and quality assurance processes. If several products arrive with a similar defect, for example, the quality control specialist might make a suggestion to improve a specific part of the manufacturing process. This helps ensure that products are produced consistently and that defects or other errors will not persist throughout the manufacturing process.
Make Necessary Repairs
In some cases, a quality control specialist may also be responsible for making necessary product repairs. If a particular product has a single, minor defect that the quality control specialist is equipped to resolve, then making this repair instead of sending the product back through the manufacturing process can save significant time and contribute to overall cost reductions.
