OTIF in Supply Chain Management: Meaning, Formula, and How to Improve Performance

Supply stability is a crucial performance indicator for supply chains, and it is monitored using OTIF (acronym of On-Time In-Full) metric to track the precision and punctuality of deliveries.

Imagine On Time In Full (OTIF) as the pulse of your supply chain. A robust and steady pulse means every part of your operation syncs—from inventory management to replenishment—ensuring products reach your stores seamlessly and on time. But when OTIF falters, it's like a weak pulse, causing disruptions that can result in stockouts, lost sales, and dissatisfied customers. McKinsey points out that companies with excellent OTIF scores meet customer expectations and are skilled at managing supply chain disruptions. This is especially important in a post-pandemic world where supply chains face constant pressure to perform reliably.

What does OTIF stand for, why is it essential for supplier-to-retailer deliveries, and how to calculate and improve this metric as part of your OTIF supply chain improvement strategy?

Key Takeaways

OTIF measures reliability and directly impacts costs & customer trust.

• Tracks orders delivered as promised. 

• Identifies supplier or logistics gaps. 

• Links to penalty or incentive contracts. 

• Improves supply chain agility. 

• Monitored continuously by category.

First things first, to understand the OTIF meaning in supply chain, think of it as a performance indicator that shows whether deliveries arrive exactly when expected and with the correct quantities. Understanding the OTIF full form helps differentiate it from other delivery metrics such as fill rate or lead time variance. It includes two key components: On-time delivery assesses whether orders arrive by the set date, and In-full delivery checks that the quantity received matches the amount ordered.

In the simplest terms, OTIF in the supply chain reflects the percentage of orders delivered on time and in the right amount without any discrepancies. Delivery on time in full is important for understanding how effectively a business fulfills its promises to customers and highlights areas for improvement.

Consider a scenario where a retailer orders 100 product units and expects delivery within five days. If the supplier delivers all 100 units on the fifth day, the order is considered on time and in full. However, if only 90 units are delivered on the fifth day or if the delivery is delayed, the OTIF score for that order will be lower, indicating that the supplier failed to meet the retailer's expectations.

On-Time In-Full (OTIF or DIFOT) performance indicator directly correlates with a company's capacity to fulfill orders accurately and punctually. A robust OTIF score signals that a supply chain operates smoothly, minimizing disruptions, curtailing expenses, and achieving maximum satisfaction. Here's why:

1. Customer focus boosts On-time In-Full (OTIF) scores. Ensuring products are on shelves when needed builds trust and loyalty, prevents stockouts, and enhances customer satisfaction. Effective supplier-retailer collaboration and diligent OTIF metric management lead to satisfied customers who drive this process.
2. Operational efficiency. Tracking OTIF can help identify issues and opportunities for improvement, leading to more efficient operations and less waste. It can also determine where the supply chain is slow and how to improve processes.
3. A strong OTIF improves financial performance. It lowers costs by reducing stockouts, excess inventory, and the need for rushed shipments. Fulfilling orders correctly on the first try also avoids expensive mistakes and returns, boosting profitability.

Calculating OTIF involves assessing both the timeliness and completeness of deliveries. Here's a breakdown of its aspects:

On-time delivery measures whether an order arrives at the retailer's warehouse by the agreed-upon date. This aspect considers factors such as lead times, transit times, and potential supply chain delays. Ensuring on-time delivery requires effective coordination between suppliers, manufacturers, and logistics providers to minimize disruptions and meet delivery schedules.

If a supplier promises delivery within three days, and the order arrives on the second day, it is considered on time. However, if the delivery occurs on the fourth day, it would be late, negatively impacting the OTIF delivery performance.

In-full delivery evaluates whether the quantity delivered matches the quantity ordered. This aspect ensures that retailers receive the complete order without shortages or discrepancies. In-full delivery requires accurate inventory management and order fulfillment processes to ensure all items are available and correctly packed for shipment.

When a retail chain orders 50 units of a product and all 50 units are delivered as expected, the order is delivered in full. If only 45 units are delivered, the order is incomplete, affecting the OTIF delivery performance.

The OTIF calculation involves dividing the number of orders delivered both on time and in full by the total number of orders placed.

In simple terms, On-Time Delivery (OT) measures whether your outgoing orders arrive on time.

The In-Full Delivery (IF) component checks whether the correct quantity arrived.

Evaluating both aspects together yields meaningful insight, assuming the orders are in good condition upon arrival.

The OTIF formula is straightforward:

The OTIF KPI, a supply chain metric, allows companies to measure performance, establish benchmarks, and foster better collaboration, ultimately making the entire supply chain run more seamlessly.

For example, Walmart and Procter & Gamble are well-known supply chains that have successfully used OTIF KPIs to identify areas for improvement. Walmart improved its inventory management and logistics using OTIF dashboard, leading to a successful OTIF supply chain with reliable deliveries and increased customer satisfaction. Which, in turn, leads to profit for both the supplier and the retailer.

Therefore, the OTIF formula can assess supplier reliability and significantly contribute to broader business objectives.

In a perfect world, suppliers would aim for a 100% OTIF score across their retailers' base. However, in reality, a solid OTIF benchmark to aim for is in the high 80% or perhaps 90% range. OTIF standards can be a moving target, as requirements vary across industries and individual retailers.

Given these high expectations, companies should focus on achieving the highest possible OTIF score and aim for consistent performance across suppliers.

Here are some situations where a good OTIF score can be a game-changer:

The cases: your shipment arrived two weeks early, and now your warehouse is overflowing, and unexpected storage costs are mounting. Or perhaps you receive double the expected volume, requiring additional handling and logistics adjustments. The On-time In-full metric helps prevent these costly scenarios by ensuring accurate deliveries, optimizing inventory management, and minimizing the need for expensive expedited shipping. Maintaining a high OTIF score enables you to reduce unnecessary logistics expenses.

What if half of your order goes missing or a delivery is late? Will you be able to stock the shelves before your customers go elsewhere? OTIF in the supply chain helps keep shoppers satisfied by ensuring they find what they need precisely when needed.

By monitoring the OTIF score, you can ensure your suppliers stay on their toes and that shelves are always stocked, keeping your customers coming back.

A high OTIF score does more than just ensure you meet delivery times. It also helps your bottom line by preventing both stockouts and excess inventory. Managing OTIF effectively means better control over your stock, which cuts down on extra costs and boosts your profits.

A high OTIF score positions companies ahead of the competition by enabling swifter responses to fluctuating markets. Moreover, OTIF aligns with sustainability goals through optimized delivery routes and waste reduction.

The following strategies can help you improve OTIF performance across your supply chain:

• Leverage historical data: Analyze past sales data, seasonality, and trends to build more accurate forecasts.
• Incorporate external factors: Consider economic indicators, demographic data, and competitive analysis to refine your predictions.
