What Is The Difference Between OTIF And DIFOT?

In the realm of supply chain management, efficiency and reliability are paramount. Businesses strive to ensure that products are delivered to customers in a timely and satisfactory manner. To measure and improve performance in this aspect, various metrics are utilized, with two prominent ones being OTIF and DIFOT.

OTIF (On Time In Full) and DIFOT (Delivery In Full On Time) are both crucial indicators of supply chain performance, yet they differ in their focus and application. This article delves into the nuances of these metrics, highlighting their definitions, significance, and disparities.

Understanding OTIF


OTIF, standing for On Time In Full, is a metric used to assess the percentage of customer orders that are delivered according to the specified requirements, both in terms of timeliness and completeness.

It measures whether products arrive at the designated destination on or before the agreed-upon delivery date and in the correct quantity and quality.


OTIF is a fundamental metric for evaluating supply chain efficiency and customer satisfaction. Achieving a high OTIF score indicates that the supply chain is effectively meeting customer demand, minimizing stockouts, and ensuring that products are available when and where they are needed.

It reflects the ability of the supply chain to fulfil orders accurately and reliably, fostering trust and loyalty among customers.


The OTIF metric is typically calculated by dividing the number of orders delivered in full and on time by the total number of orders, expressed as a percentage. It provides insights into the overall performance of the supply chain in meeting customer expectations.

Key Components:

  • On-Time Delivery: This aspect of OTIF measures the percentage of orders that are delivered by the agreed-upon delivery date. Late deliveries can lead to dissatisfaction among customers and disrupt their operations.
  • In-Full Delivery: In-Full Delivery evaluates whether the complete order is delivered without any missing or damaged items. Partial deliveries or incorrect quantities can result in additional costs and inconvenience for customers.

Understanding DIFOT


DIFOT, which stands for Delivery In Full On Time, is another vital metric in supply chain management that focuses specifically on the timely and complete delivery of customer orders. Like OTIF, DIFOT emphasizes the importance of meeting customer expectations regarding delivery performance.


DIFOT is a key performance indicator (KPI) that provides insights into the effectiveness of the supply chain in fulfilling customer orders accurately and punctually. By monitoring DIFOT metrics, businesses can identify areas for improvement and implement strategies to enhance delivery reliability and efficiency.


Similar to OTIF, DIFOT is calculated by dividing the number of orders delivered in full and on time by the total number of orders, expressed as a percentage. However, DIFOT places equal emphasis on both timeliness and completeness of delivery.

Key Components:

  • Delivery On Time: Timely delivery is a critical aspect of DIFOT, measuring the percentage of orders that are delivered by the agreed-upon delivery date or within the specified timeframe. Delivery delays can lead to dissatisfaction and have ripple effects across the supply chain.
  • Delivery In Full: Delivery In Full evaluates whether the entire order is delivered without any missing or incorrect items. It ensures that customers receive the products they ordered in the right quantity and condition, minimizing disruptions and avoiding additional costs.

Key Differences Between OTIF and DIFOT

While both OTIF and DIFOT are metrics used to assess supply chain performance, they differ primarily in their focus and emphasis:

  • Focus:
    • OTIF primarily emphasizes the completeness of orders, ensuring that all items are delivered as requested, while also considering timeliness.
    • DIFOT, on the other hand, places equal emphasis on timeliness and completeness, considering both aspects essential for customer satisfaction.

  • Calculation Method:
    • Both metrics are calculated using the same formula: dividing the number of orders delivered in full and on time by the total number of orders. However, they may vary slightly in terms of how timeliness and completeness are measured and weighted.

  • Application:
    • OTIF is commonly used in industries where order completeness is critical, such as retail and manufacturing, where stockouts or missing items can significantly impact operations.
    • DIFOT is more broadly applicable and is used across various industries to evaluate overall delivery performance, considering both timeliness and completeness as essential factors.

  • Customer Perspective:
    • From a customer perspective, both metrics are important indicators of service quality and reliability. However, customers may prioritize either timeliness or completeness based on their specific needs and preferences.


In summary, OTIF and DIFOT are two essential metrics in supply chain management that focus on evaluating the timeliness and completeness of customer order deliveries. While OTIF emphasizes order completeness with consideration for timeliness, DIFOT places equal importance on both aspects.

By measuring and monitoring these metrics, businesses can gain valuable insights into their supply chain performance, identify areas for improvement, and enhance customer satisfaction.

Ultimately, a robust supply chain that consistently achieves high OTIF and DIFOT scores is essential for driving operational efficiency, reducing costs, and maintaining a competitive edge in the marketplace.


What Is Otif Reporting?

OTIF reporting refers to the process of tracking, analyzing, and presenting data related to On Time In Full (OTIF) performance within a supply chain or logistics operation.

OTIF reporting plays a crucial role in evaluating the effectiveness of supply chain processes, identifying areas for improvement, and ensuring that customer orders are delivered according to expectations.

OTIF reporting is a critical component of supply chain management that enables organizations to monitor, evaluate, and improve their order fulfilment performance.

By collecting and analyzing data on delivery timeliness and completeness, organizations can identify opportunities for optimization, enhance customer satisfaction, and drive operational excellence.

OTIF reporting facilitates data-driven decision-making, fosters continuous improvement, and ultimately contributes to the success and competitiveness of businesses in today’s dynamic marketplace.

What Is The Formula For OTIF KPI?

The formula for calculating the OTIF (On Time In Full) Key Performance Indicator (KPI) is relatively straightforward. It involves dividing the number of orders delivered on time and in full by the total number of orders and then multiplying by 100 to express the result as a percentage.

Here’s the formula in detail:

OTIF=(Number of Orders Delivered On Time In Full/Total Number of Orders) x 100

In this formula:

  • “Number of Orders Delivered On Time In Full” refers to the total count of orders that were delivered according to the agreed-upon delivery date and in the correct quantity and quality.
  • “Total Number of Orders” represents the overall number of orders fulfilled within the specified time.

By calculating this formula, you can determine the percentage of orders that were successfully delivered on time and in full, providing a valuable measure of supply chain performance and customer satisfaction.

What Is Difotai?

“DIFOTAI” is an acronym that stands for “Delivery In Full On Time And Invoiced.” It is an extension of the DIFOT (Delivery In Full On Time) metric, incorporating the additional aspect of accurate and timely invoicing into the evaluation of supply chain performance.

DIFOTAI provides a comprehensive measure of supply chain performance, encompassing not only the timely and complete delivery of customer orders but also the accuracy and efficiency of invoicing processes.

By considering all these aspects together, organizations can gain a more holistic understanding of their ability to fulfil customer requirements and maintain satisfaction throughout the order-to-invoice cycle.

The DIFOTAI metric is typically calculated by combining the individual performance percentages for delivery in full, delivery on time, and accuracy of invoicing. The formula for DIFOTAI may vary depending on the specific criteria and weight assigned to each component.
