Prime ambition of Rhein S.Q.M. is to provide superior services. Whether and to what extend we reached our guidance level is regularly analysed with a customer satisfaction questionnaire. Every year customers evaluate issues like (service) quality, our flexibility or price-performance-ratio on a scale between 1 (= very good) and 5 (= inadequate). In 2022 we were again able to outperform the excellent values of the previous years. These positive results will be an essential driving force for our work in diverse customer projects.
