"We are the office of GfK Turkey and as such we sought to identify business partners who could reinforce our high performance culture in the field of quantitative and qualitative research, data collection and processing. As a result, we chose one Promena e-Sourcing system, who works under Koç Holding - one of the foremost holding companies in Turkey.We drew a great amount of interest from GfK Global purchasing as we were among the first to implement this method in Turkey. With this e-procurement method we implemented a multi-purpose supplier selection process. Beyond being transparent and fair, we have also identified business partners with whom we can collaborate to increase our competitiveness in the field in line with GfK standards in a reliable and efficient manner. Thank you to the Promena team, with whom we co-managed with this process."
