Step-by-step explanation:
Inspection reports used to monitor the quality of raw materials delivered to manufacturers are an example of preliminary control.
Preliminary control refers to measures taken in advance to identify and prevent potential problems before they occur. In this case, inspection reports help manufacturers assess the quality of their raw materials to ensure that they meet the required standards and specifications. By conducting inspections and reviewing the reports, manufacturers can identify any issues or deviations from quality standards early on and take corrective measures.
For example, if a manufacturer receives a batch of raw materials with a higher-than-acceptable level of impurities, the inspection report will highlight this issue. The manufacturer can then take appropriate actions such as rejecting the batch, notifying the supplier, or requesting replacements to ensure that only high-quality materials are used in the production process.
