What does a quality inspector do? - A quality inspector typically works in the manufacturing industry to ensure that the standards set forth by top engineers continue throughout the production process. Also known as quality-control inspectors or product testers, these professionals are counted on by management to spot defects in a company's products before consumers have the chance to. Though various quality-control certification agencies exist to provide more generalized training, many companies tailor their quality-assurance programs to suit their particular mission and product line.
