This study aims to identify problems and inefficiencies in the shipment monitoring process at PT X, design an improved business process, and develop a shipment monitoring system application aligned with the proposed process. The research used a qualitative case study approach, with data collected through structured interviews, direct observation, and documentation study. The analysis applied Business Process Improvement through the stages of organizing for improvement, understanding the process, and streamlining. The current and proposed processes were modeled using Business Process Model and Notation, while the root causes of inefficiency were analyzed using a fishbone diagram based on the 4M categories. The findings show that the existing monitoring process still relies on e-mail and Excel reports from forwarders, causing information delays, manual data recap, reactive SLA checking, and late detection of delivery problems. The proposed process directs monitoring toward a centralized system where forwarders update shipment status directly, SLA compliance is checked automatically, and supporting documents are stored in the same system. The application design includes a monitoring dashboard, shipment data input, status updates, status history, delay notification, monitoring reports, issue notes, and proof uploads. This design is expected to make shipment monitoring more centralized, documented, responsive, and easier to control.
