Evaluating Supply Chain Performance Based on Delivery Performance Analysis Chart Approach

On-time delivery is a primary determinant of customer satisfaction in a supply chain. Measuring and improving delivery performance for a supply chain is always desirable to increase competitiveness in the modern business environment. To assess delivery performance of each stage in a supply chain, in this paper, we integrate the process capability index C_pk and Motorola six-sigma quality levels to present a delivery performance analysis chart (DPAC). Based on the plotting points on the DAPC, practitioners can simultaneously visualize some important information such as the delivery accuracy and precision of each stage and provide improvement directions of delivery performance in a supply chain. The proposed methodology is illustrated by an example of an apparel-industry supply chain.
