The Korea Transportation Safety Authority saw remarkable improvements with implementing the OZ e-Form. They were able to streamline their work processes and increase the accuracy of their inspections, resulting in a savings of 3,200 work hours per year and a 10% increase in workforce efficiency. Additionally, they reduced their paper usage by 390,000 sheets annually. Inspection processing time was also drastically reduced from 20 days to just one day. We enabled the inspection result to be guided through various communication channels, including web portals, mobile devices, and SMS, allowing for real-time communication and increased transparency in their operations.
