What is OTIF?

On-Time In-Full (OTIF) is a key performance indicator that measures the efficiency and accuracy of supply chain operations. It evaluates how often a company delivers the correct order quantities on the agreed-upon delivery date, thereby meeting customer demand.

OTIF consists of two components:

  1. On-time deliveries. This refers to the orders delivered to the customer at the right time as scheduled or earlier.
  2. In-full deliveries. This assesses whether the complete order was delivered without any items missing, as per the customer’s requirements.

OTIF is one of the most important supply chain metrics that can be used to assess both your own delivery accuracy as well as that of suppliers.

Key benefits of OTIF

The OTIF KPI is a comprehensive measure that impacts almost every facet of supply chain management. Here’s how it can help your company:

  • Improves supplier performance. OTIF is an effective metric for assessing how well suppliers adhere to delivery schedules and order accuracy. High OTIF scores indicate reliable suppliers, while low scores may prompt a review of supplier contracts and performance.
  • Improves inventory management. Proper implementation of OTIF helps ensure that inventory levels are optimized. By receiving goods on time and in the correct quantities, companies can avoid overstocking or stockouts, allowing for more efficient inventory turnover, and reduced holding costs.
  • Reduces supply chain disruptions. OTIF directly addresses potential disruptions in the supply chain by highlighting issues in on-time delivery and in-full delivery. Identifying these issues in a timely manner allows businesses to implement corrective actions without significant delays, thus maintaining the smooth operation of the supply chain.
  • Increases customer satisfaction. For manufacturers, distributors, retailers, and e-commerce businesses, the ability to deliver orders accurately and on time is crucial. High OTIF performance often correlates with increased customer satisfaction, as customers are more likely to be happy when they receive what they ordered within the promised timeframe.
  • Supports effective order fulfillment. OTIF aids in improving the accuracy and timeliness of order fulfillment. This not only helps in reducing late deliveries but also ensures that customers receive complete orders, which is vital for maintaining trust and loyalty.
  • Facilitates better supply chain management. By monitoring OTIF, businesses can identify and address bottlenecks in the supply chain more effectively. This continuous improvement process is essential for staying competitive in the market and meeting consumer demands efficiently.
  • Benchmarking and continuous improvement. OTIF serves as a benchmark for measuring the success of supply chain initiatives. Companies can set specific OTIF targets and measure their progress over time, allowing for continuous improvement in supply chain performance.

Businesses that prioritize high OTIF performance are therefore better equipped to meet market demands and maintain a competitive edge.

How to calculate the OTIF rate?

Calculating the OTIF rate involves assessing the proportion of deliveries that are both on time and complete. Here is a detailed breakdown of how to calculate the OTIF rate.

  1. Define the delivery window. The delivery window is the agreed-upon time frame between a supplier and a customer for when goods should be delivered. This lead time is crucial for determining whether a delivery is considered “on-time.”
  2. Identify relevant deliveries. Compile data on all deliveries made within a specific period. This dataset should include the delivery date, the quantity of items ordered, and the quantity actually delivered.
  3. Count the deliveries made on time and in full. Count the number of deliveries that arrived within the specified delivery window and in the agreed-upon quantity.
  4. Calculate OTIF. The metric is calculated by dividing the number of orders delivered on time in full by the number of total deliveries.

The OTIF rate formula is therefore:

OTIF = On-time-in-full deliveries / Total deliveries

Example

Assume you have the following delivery data for a month:

Total deliveries: 100

On-time-in-full deliveries: 90

OTIF = 90 / 100 = 0.9 = 90%

What is a good OTIF score?

Good OTIF scores are those that meet or exceed industry benchmarks and company-specific targets. While a perfect OTIF score is 100%, meaning every order is delivered on time and in full, this level of performance is challenging to achieve consistently due to various uncertainties in supply chain dynamics. However, an OTIF score around 95% to 99% is often considered excellent in many industries. Such high scores indicate a highly efficient supply chain with effective optimization strategies in place, leading to high customer satisfaction and operational excellence.

A bad OTIF score, on the other hand, typically falls below 85%. Such scores may indicate significant issues within the supply chain, including poor supplier reliability, warehouse management problems, or ineffective supply chain strategies. Low OTIF scores can lead to customer dissatisfaction, increased operational costs, and potential loss of business and profitability as customers seek more reliable vendors.

Possible root causes of low OTIF scores

A low On-Time In-Full (OTIF) score can significantly impact a business’s ability to meet customer expectations and maintain efficient operations. Identifying the root causes of a low OTIF is crucial for implementing effective corrective measures. Here is a closer look at the potential factors contributing to underperformance in OTIF metrics.

Supplier-related issues

Poor supplier performance

If suppliers consistently fail to deliver goods on time or ship incorrect quantities or items, it will directly impact the OTIF score.

Ineffective communication

Lack of clear and timely communication between suppliers and the purchasing company can lead to misunderstandings about order specifications or changes in order requirements.

Logistics and transportation problems

Inefficient routing

Suboptimal transportation routes or logistic strategies can cause delays in delivery times.

Carrier issues

Problems with transportation providers, such as capacity constraints, operational delays, or errors, can prevent on-time delivery.

Customs and import delays

For international shipments, delays in customs can hinder the timely arrival of goods, especially if there is incomplete or incorrect paperwork.

Internal process inefficiencies

Inventory management shortfalls

Inaccurate inventory records or poor warehousing practices can result in being unable to fulfill orders fully from available stock.

Production delays

In manufacturing contexts, delays in production due to equipment malfunctions, workforce issues, or supply chain bottlenecks can prevent orders from being completed on time.

Order processing errors

Mistakes in order handling, from incorrect data entry to delays in processing customer orders, can lead to wrong or delayed shipments.

Demand forecasting and planning issues

Inaccurate demand forecasting

Poor forecasting of customer demand can lead to either inventory surplus or shortage, affecting the ability to fulfill orders promptly and completely.

Lack of flexibility in supply chain

Inability to adapt to sudden changes in market demand or supply chain disruptions can severely impact OTIF performance.

External factors

Market volatility

Fluctuations in the market can affect supply and demand unpredictably, impacting the availability of materials and final products.

Regulatory changes

New regulations or changes in existing laws can alter shipping routes, import and export conditions, or product specifications, leading to delivery delays or failures.

Natural disasters and pandemics

Events like hurricanes, earthquakes, or health crises can disrupt normal operations along the entire supply chain, from production to delivery.

How to optimize your OTIF score?
