The COVID-19 pandemic has harmed automotive vehicle sales. A lot of automotive companies have shifted their focus from sales to after-sales service, and the trend in after-sales service is starting to recover and has a big contribution to the revenue. Along with the growth of digital technology and e-commerce, automotive companies must adapt and develop new strategies to compete with their competitors and maximize their potential in after-sales service. This study aims to design business process improvements by using Business Process Reengineering (BPR) to increase the time efficiency of the after-sales service journey in one of the automotive companies in Indonesia. The method is used to design improvements to the service journey using the iGrafx software. Improvements are carried out on the whole journey of car service, starting from customer reception until service delivery and payment. Data collection regarding the car service process was collected in one of the automotive companies in Indonesia. The method consists of three steps namely mapping as-is process, analyzing as-is process, and modelling to-be process. The results of this study obtained an improvement scenario of a to-be process with the highest reduction in time.
