Supply Chain Risk Management of Aftermarket Products in Automotive Spare Parts Manufacturing Companies Using the House of Risk (HoR) Method

This study was conducted at an automotive component manufacturing company that produces aftermarket products. This study aims to identify risk events and agents that occur in the supply chain and develop strategies to control existing risks so as to minimize losses. The method used is the House of Risk (HoR). In HoR phase 1, 19 risk events were identified, with 38 risk agents as risk causes. From HoR phase 1, eight priority risks were selected. HoR phase 2 was carried out by determining a mitigation strategy plan with 16 mitigation actions, and then 7 priority mitigation actions were selected based on the effectiveness ratio obtained from the level of difficulty in realizing the mitigation action. Priority mitigation actions that will be carried out include conducting technology evaluations, providing supporting tools such as barcode scanners, creating clear work instructions, reviewing and updating SOPs, conducting three-point checks, conducting systematic quality control, and setting quality limits.
