Starbucks uses several quality systems. The first starts with the baristas on the floor. The drinks are called from the barista on the point of sale to the barista making drinks. This is then recalled to the first barista. When the drink is called back it is checked for accuracy as well as making sure no drinks are missed. After the drink is made the barista checks the drink for accuracy before handing it off to the customer. A second system that Starbucks uses is random check ins from District Managers (DM). In these check in the DM talks to the customers, watches the baristas, and do random checks of drinks to ensure quality. The final system the Starbucks uses is a third party. Starbucks uses a company called ECOSURE to to perform checks on all the stores to ensure all quality standards are met every six months. The stores have a copy of the required qualifications that it must meet to prepare for these checks as well as maintain these standards.
