Knowing Warehouse Picking Time Standards

Warehouse picking time is a critical metric that influences the efficiency, accuracy, and overall performance of a warehouse. Understanding and optimizing picking time standards is key to reducing operational costs, improving order fulfillment speed, and meeting customer expectations. As businesses strive to meet increasing eCommerce demand and handle large volumes of orders, reducing picking times without sacrificing accuracy has become a primary goal for modern warehouses. In this article, we will explore what warehouse picking time standards are, the factors that impact them, and how businesses can optimize their picking processes for better efficiency.

What Are Warehouse Picking Time Standards?

Warehouse picking time standards refer to the expected or average amount of time it takes for workers to locate, pick, and prepare items for packing and shipping. These standards can vary depending on the warehouse size, product types, and picking methods in use. By setting specific time standards, warehouse managers can measure worker performance, optimize processes, and ensure that customer orders are fulfilled in a timely manner.

Several factors affect picking time, including the warehouse layout, product types (small, bulky, or fragile), and the technology or automation used during picking. Monitoring and improving these standards helps businesses enhance productivity and maintain accurate and timely deliveries.

Key Factors That Impact Picking Time

Warehouse picking times are influenced by a range of factors, all of which play a role in the speed and efficiency of the picking process. Here are the key factors to consider:

• Warehouse Layout and Size: The size of the warehouse and the design of its layout greatly affect picking time. Larger warehouses may require workers to travel longer distances between picking locations, leading to slower times. A well-organized layout, with frequently picked items located near packing stations, can drastically reduce travel time and improve efficiency.
• Type of Products: The type of products being picked also impacts the time it takes. Small, lightweight items are generally easier and faster to pick than bulky or fragile items that require careful handling. Warehouses that deal with a wide variety of products may have to adjust their picking time standards accordingly.
• Picking Method Used: The strategy or method used for picking—whether it’s zone picking, batch picking, or wave picking—can significantly impact picking time. For example, batch picking allows workers to pick items for multiple orders simultaneously, reducing redundant trips, while zone picking assigns workers to specific areas to minimize travel time.
• Technology and Automation: The use of technology, such as barcode scanners, warehouse management systems (WMS), and automated picking systems, can speed up the picking process by reducing manual work and increasing accuracy. Automation is particularly effective in high-volume warehouses, where speed is critical.

By addressing these factors, warehouses can optimize their picking time standards, improving both speed and accuracy.

Industry Benchmarks for Warehouse Picking Time

Industry benchmarks for warehouse picking time vary depending on the sector, order volume, and the complexity of the products being handled. These benchmarks provide a reference for measuring efficiency and can help warehouses set realistic goals. Common benchmarks include:

• Picks per Hour: A typical benchmark for manual picking ranges between 60 to 120 picks per hour for small to medium-sized items. In highly automated facilities, this can be much higher, with some reaching over 400 picks per hour.
• Travel Time: In larger warehouses, travel time can account for as much as 50% of the total picking time. Optimizing travel routes and reducing unnecessary movement is crucial for improving efficiency.
• Order Accuracy: Accuracy benchmarks vary, but warehouses generally aim for an order accuracy rate of 99.5% or higher. While speed is important, maintaining accuracy ensures customer satisfaction and minimizes the costs associated with returns or re-picks.

Benchmarks will differ between industries. For example, e-commerce warehouses handling small consumer goods may have higher picks per hour, while warehouses dealing with bulky or fragile items, such as in manufacturing or retail, may have lower rates due to the additional care required.

How to Measure and Calculate Picking Time

To optimize picking time, it’s essential to accurately measure and track performance. Here are some key metrics to consider:

• Picks per Hour (PPH): This metric measures the number of items a worker can pick in one hour. It’s a direct reflection of picking speed and can be used to evaluate the efficiency of individual workers or the overall warehouse process.
• Pick Accuracy: This metric tracks how often orders are picked correctly, without errors. While it’s important to speed up picking times, accuracy should not be sacrificed. Pick accuracy is measured by the percentage of orders fulfilled correctly out of the total orders processed.
• Travel Time: Tracking the amount of time workers spend traveling between picking locations is crucial for identifying inefficiencies. Warehouses can use route optimization tools to minimize this time and increase productivity.

To calculate average picking time, track the total time it takes to complete a set number of picks and divide it by the total number of picks. For example, if a worker picks 100 items in two hours, their average pick time would be 1.2 minutes per pick. Warehouses can use this data to compare actual performance against benchmarks and adjust processes accordingly.

Role of Technology in Improving Picking Time

Technology plays a key role in reducing picking time and improving overall warehouse efficiency. Here are some of the technological tools that can help:

• Warehouse Management Systems (WMS): A WMS provides real-time data on inventory levels, order status, and picking routes. It helps automate tasks like assigning orders to pickers and optimizing picking routes, making the process faster and more accurate.
• Barcode Scanning and Mobile Devices: Barcode scanners and mobile devices are essential for reducing errors and speeding up the picking process. Workers can scan items as they pick them, ensuring that the correct products are selected. This also updates inventory levels in real time, reducing the need for manual data entry.
• Automation and Robotics: Automated picking systems and robots can drastically reduce picking times by handling repetitive tasks faster and more accurately than human workers. These systems are especially beneficial in large warehouses or for handling high-volume, high-frequency orders.

By leveraging these technologies, warehouses can significantly reduce picking times, improve accuracy, and better meet customer demand.

Strategies to Reduce Picking Time

Reducing picking time is essential for boosting warehouse efficiency, and there are several strategies that warehouses can implement to streamline the process. These strategies focus on optimizing workflows, reducing unnecessary movement, and enhancing worker productivity.

• Implementing Optimized Picking Routes: One of the most effective ways to reduce picking time is to optimize the routes that workers follow when retrieving items. Warehouse management systems (WMS) can calculate the shortest, most efficient paths between picking locations. This reduces the time workers spend walking and helps them pick items faster.
• Training Staff for Efficiency: Proper training is key to reducing picking time. Workers should be trained not only in the mechanics of picking but also in how to use technology like barcode scanners and mobile devices. Additionally, training should emphasize speed without sacrificing accuracy, teaching employees how to balance both effectively.
• Minimizing Travel Time Through Better Layout Design: Warehouse layout plays a significant role in picking speed. Frequently picked items should be stored in easily accessible locations near the packing area. Implementing a logical, well-organized layout can help minimize the distance workers need to travel between picks, significantly reducing picking time.

By adopting these strategies, warehouses can reduce picking times while maintaining accuracy and productivity.

Optimizing Picking Time for High-Demand Periods

During high-demand periods, such as holidays or sales events, warehouses often struggle to keep up with the increased volume of orders. Optimizing picking time becomes even more critical during these periods to ensure timely fulfillment without compromising quality.

• Adjusting Standards During Peak Seasons: During peak times, picking time standards may need to be adjusted to account for the higher volume of orders. Warehouses should plan ahead by scheduling additional shifts, using temporary workers, or employing batch picking methods to handle the increased workload efficiently.
• Hiring Temporary Staff and Training Them Quickly: Bringing on temporary staff can help manage the extra workload during peak periods. However, to maintain productivity, it’s essential to provide fast, effective training. Use simplified workflows and technology like mobile devices to ensure temporary staff can pick orders accurately and efficiently with minimal onboarding time.
• Using Batch Picking and Automation to Manage High Volumes: Batch picking, where multiple orders are picked simultaneously, is an excellent way to handle high-volume periods. Automation, such as conveyor belts or robotic picking systems, can further streamline the process, allowing warehouses to handle large numbers of orders in a shorter time frame without overwhelming staff.

By preparing ahead and utilizing these techniques, warehouses can maintain fast picking times even during their busiest periods.

Improving Picking Accuracy Without Compromising Speed

While reducing picking time is important, maintaining accuracy is equally crucial. Mistakes in the picking process can lead to costly returns, re-picking, and dissatisfied customers. Here are ways to balance speed with accuracy:

• Balancing Speed with Accuracy: Speed and accuracy don’t have to be mutually exclusive. Workers should be trained to prioritize accuracy while working efficiently. Encouraging a mindset of “accurate first, fast second” can help maintain quality without significantly slowing down operations.
• Using Technology Like Barcode Scanners to Reduce Errors: Barcode scanners are a simple yet powerful tool for maintaining accuracy. By scanning items during the picking process, workers can ensure they are selecting the correct product. Barcode systems integrated with WMS software can flag errors in real-time, allowing workers to correct mistakes before orders move to the packing stage.
• Quality Control Measures During the Picking Process: Implementing quality control checkpoints throughout the picking process can help reduce errors. For example, double-checking high-value or high-priority orders before they are packed ensures that the right items have been picked. This may add a few extra seconds per order but can save time and costs related to re-picking and returns.

Maintaining a balance between speed and accuracy ensures that warehouses can meet customer expectations without sacrificing quality.
