The DMAIC method is one of the Six Sigma tools that can be used to improve performance with a systematic level of analysis to eliminate non added value. This methode is usually applied in production process, but it can also be used for the supply chain sector. In the case of accuracy time of material procurement until its delivery to the site, corrective measures are performed using the Ishikawa diagram to determine the problem of the process stage. The improvements are focused on consistency in making the Shipping List and scheduling delivery time to the site warehouse.The results of this research were increase in accuracy from 34% to 71% after improvements were made.
