Challenge

Comparing to the fresh and high quality data of user acceptance testing (UAT) systems in İş Bank, integration and prior test systems had lower quality and older data. For this reason developers tended to use UAT systems for testing purposes which resulted integration and test systems being underutilized while the UAT environments become too crowded and overutilized.
