The delivery service level describes the percentage of deliveries completed on time and in full in relation to the total number of all deliveries. For Purchasing, this KPI is essential for evaluating supplier performance and ensuring a stable supply.
Example: An automotive supplier achieves a delivery service level of 98.5% by receiving a total of 985 deliveries on time and in full out of 1,000 deliveries in the first quarter of 2023, while 15 deliveries have deviations.
The delivery service level is a key figure that indicates the extent to which a company can fulfill its customers' orders in full and on time. It measures the ability to deliver the desired quantity of a product to the right place at the right time. A high delivery service level is an indicator of efficient logistics and customer-oriented processes.
In purchasing, the delivery service level is a key criterion when evaluating suppliers. A high delivery service level has a direct impact on end customer satisfaction and supply chain efficiency. By monitoring this key figure, buyers can identify potential bottlenecks at an early stage, optimize stock levels and strategically select suppliers.
The delivery service level is a key indicator of supply chain performance and has a direct impact on customer satisfaction. Traditionally, it was recorded manually, which was time-consuming and error-prone. In an increasingly digitalized world, however, there is a need to optimize this process and respond more quickly to deviations. The transformation to digital methods enables more precise and efficient monitoring of the delivery service level.
Traditional approach: In the past, delivery service level data was often collected manually from various sources. Employees collected information from delivery bills, orders and demand analysis and entered it into spreadsheets. The evaluation was usually carried out monthly or quarterly, which led to delays in identifying problems. In addition, manual data entry was prone to errors and inconsistent data, which impaired the reliability of the analyses. The time required meant that companies could only react to delivery deviations to a limited extent and were unable to avert potential effects on production or customer service in good time.
Real-time analytics: Modern companies rely on digital technologies and real-time analyses to continuously and precisely monitor the delivery service level. By integrating ERP systems, SCM software and IoT sensors, delivery data is automatically recorded and analyzed in real time. Risk management and machine learning algorithms analyze patterns and predict potential delivery bottlenecks or delays. This enables proactive measures to be taken, such as adjusting order quantities or rerouting deliveries. Real-time monitoring not only improves the accuracy of the data, but also increases flexibility and reaction speed within the supply chain. As a result, companies can significantly increase their delivery service level and boost customer satisfaction.
An electronics manufacturer implemented a real-time tracking system to monitor its delivery service level. Thanks to automated data collection and the use of advanced analytics, the delivery service level rose from 90% to 99% within six months. At the same time, the stock levels reduced by 20% as the improved transparency in the supply chain enabled more accurate demand forecasting. The company benefited from reduced costs and increased customer satisfaction as delivery dates were met more reliably.
The delivery service level is an essential key performance indicator for evaluating logistics efficiency and customer satisfaction. Its systematic recording and optimization enables companies to improve their supply chains, reduce costs and achieve competitive advantages. By using modern technologies and strategic supplier management, companies can achieve a high delivery service level and secure it in the long term.
