A method of examining the product inspection is provided, which includes the following steps. Perform an inspection step multiple times to obtain the inspection data of the products, and record the inspection data in the product items in the database. The first party selects a plurality of product items from the product items in the database through the first electronic device. The data management system generates a check code corresponding to the check items, and generates a notification message. After the second party responds to the notification message through the second electronic device, the data management system determines whether the inspection data of each of the check items satisfies the corresponding check condition, and transfers the check items satisfying the check condition to the second electronic device. Thereby, it would be more convenient to examine the product inspection.
