As a quality control procedure, management at Roger Company reviews each approved vendor at least once a year. In the reviews, management compares pricing across vendors, retests products being purchased from vendors to ensure they meet quality control standards, and performs testing to ensure purchasing personnel are not inappropriately favoring a vendor or potentially colluding with vendors (e.g., receiving kickbacks from the vendors). Use IDEA to check the Roger Company Vendors table to make sure each vendor has been reviewed sometime since January 1, 2021
