Customer needs for automotive products are still increasing, this has forced the automotive assembly industry to
focus more on productivity and make measurement adjustments and improvements to produce products that meet
customer demands and improve performance. As one of the largest automotiveare unprepareds in Indonesia, PT
Astra Honda Motor faces complex problems related to increasing customer demand which is not in accordance with
the plan, reducing component availability and disrupting the production process, while also causing greater
performance losses, including operators who unprepared, erratic machine cycles can even be slower because they
have to work not according to machine capacity, it can even cause start-up defects in machines used for production
processes. All that of course resulted in quality problems becoming more frequent. The overall productivity of the
integrated manufacturing system through the overall effectiveness of the equipment regardless of capabilities, and
flexibility is considered insufficient as a solution to drive improvements and improve performance. Therefore, PT
Astra Honda Motor must pay attention to equipment flexibility and overall equipment effectiveness (OEEFlex) to
address customer requests. This study aims to identify losses related to the effectiveness of the equipment as a whole
and the possibility of repairs carried out by implementing equipment flexibility that can drive the repair process, this
is done by looking at the planning, losses, and availability of parts by eliminating unplanned events by finding the
causes and take precautions. This study provides a contextual model of overall equipment effectiveness and
equipment flexibility that will help automotive assembly companies meet customer demands through customization.
