• Importance: Measures the effectiveness of inventory management in preventing stockouts. Lower rates indicate better inventory control.

Carrying Cost of Inventory:

• Definition: The total cost associated with holding inventory, including storage, insurance, and obsolescence.

• Formula: (Carrying Costs / Total Inventory Value) x 100

• Importance: Helps in assessing the financial impact of inventory holding. Lower carrying costs indicate more efficient inventory management.

Inventory Accuracy:

• Definition: The accuracy of inventory records compared to actual physical inventory.

• Formula: (Number of Accurate Inventory Records / Total Number of Inventory Records) x 100

• Importance: Ensures that inventory records are reliable and align with actual stock levels, reducing discrepancies and errors.

4. Order Fulfillment Metrics

Order fulfillment is a key driver of customer satisfaction, and tracking performance in this area is crucial for meeting customer expectations.

Order Cycle Time:

• Definition: The total time taken from order receipt to order delivery.

• Formula: Order Delivery Date - Order Receipt Date

• Importance: Measures the efficiency of the order fulfillment process. Shorter cycle times indicate faster order processing and delivery.

Perfect Order Rate:

• Definition: The percentage of orders delivered without any issues such as delays, damage, or inaccuracies.

• Formula: (Number of Perfect Orders / Total Number of Orders) x 100

• Importance: Reflects the overall effectiveness of the order fulfillment process. A higher rate indicates better performance in delivering orders as promised.

Order Fill Rate:

• Definition: The percentage of customer orders that are fulfilled in full without backorders.

• Formula: (Number of Orders Fulfilled in Full / Total Number of Orders) x 100

• Importance: Indicates the ability to meet customer demand without delays or partial shipments. A higher fill rate enhances customer satisfaction.

5. Customer Service Metrics

Customer service is a critical component of logistics performance, impacting customer satisfaction and loyalty.

Customer Satisfaction Score (CSAT):

• Definition: A measure of customer satisfaction with logistics services.

• Formula: Average Satisfaction Rating (typically gathered through surveys)

• Importance: Provides insight into how customers perceive the quality of logistics services. Higher scores indicate better customer satisfaction.

Net Promoter Score (NPS):

• Definition: A measure of customer loyalty and likelihood of recommending the company’s services.

• Formula: % Promoters - % Detractors

• Importance: Indicates the overall customer experience and loyalty. A higher NPS suggests positive customer experiences and strong brand advocacy.
