Business operations require quality control (QC) standards. Having the proper set of QC procedures in place ensures manufactured products or services adhere to defined quality criteria. Procedures can be built around product specifications, such as size, qualitative aspects or function.

Standard Operating Procedures

Standard Operating Procedures (SOPs) are high-level procedures that govern general quality management policies and direct the handling of specific quality systems. These procedures typically include responsibilities and procedural steps.

Test Procedures

Companies employ quality control test procedures when a product must meet certain specifications. Instruction is given for how the test must be performed. The test results must meet specific criteria. Direction also is included for what action is taken if the product results are out of specification.


Audit Procedures

Procedures are useful only if employees adhere to the rules. Audit procedures provide mechanisms for auditing process outputs and trending those results for potential improvements. Audit procedures help bring the quality control system full circle and provide valuable feedback on how the system is functioning.
