At the beginning, the test farms often receive several products at the same time. However, the timing of the tests is basically individual. Depending on the product, they remain in use for a longer period of time in order to be able to understand the wear process; in the case of porcelain, we test for several months. ‘If there is no time in the hectic of everyday life, tests can also be paused; in our case it was recently two months. Before that, we tested a lot of products in parallel for three months. Since we have a total of four restaurants, we can also test many different products in parallel,’ says Papageorgiou.
This is how the feedback reaches METRO
METRO first uses standardised questionnaires to gather customers' opinions. In personal conversations, problems with the products and possible solutions are brought to the table. ‘The conversations are always very open. If a product is still unsuitable, METRO picks it up very quickly and revises it or finds an alternative. It's a fluid process,’ says Papageorgiou.
Based on the customer feedback, the METRO experts improve the product and it goes back to the product testers. Then the quality is 100% right - for permanent use by professionals.
