Picking is one of the most crucial activities within logistics and warehouse management. A good execution of this process can make a difference in the operational efficiency, customer satisfaction and profitability of a company. Below, we will explore the importance of optimizing picking, the benefits it brings and the main strategies to achieve it.
What is picking and why is it important to optimize it?
Picking refers to the process of selecting and collecting products in the warehouse to fulfill customer orders. It represents one of the most critical steps in the logistics chain, as any error or delay can lead to delivery delays and, consequently, affect customer satisfaction.
Optimizing this process involves implementing work methods, technologies and good practices that reduce times, minimize errors and make the most of available space and resources. By doing so, companies can significantly improve their competitiveness and profit margins.
What is the importance of picking in the supply chain?
Picking is an essential link that connects various phases of the supply chain, from the receipt of raw materials to the delivery of finished products to the customer. Efficient picking allows:
Maintaining operational fluidity: It ensures that products move quickly between different stages (storage, packaging, shipping, etc.).
Avoiding bottlenecks: A slow or inefficient picking process can delay the entire supply chain.
Reducing costs: By optimizing picking, errors and rework are minimized, which results in lower operating costs.
Improving service quality: Faster and more accurate deliveries increase customer satisfaction and strengthen brand image.
Benefits of picking optimization
Increased Productivity: Staff can complete more orders in less time.
Reduced Errors: Improving picking methods reduces the likelihood of inventory errors or wrong shipments.
Cost Savings: A more agile operation results in lower labor costs and more efficient use of resources.
Improved Customer Satisfaction: Orders delivered on time and with the desired accuracy translate into more loyal customers.
Optimized Warehouse Space: A well-designed layout and the implementation of appropriate technologies help to make better use of the facilities.
Strategies to optimize picking
Picking optimization requires a combination of planning, technology and staff training. Below, we will review the main strategies and actions to achieve this.
Warehouse organization
The basis for efficient picking lies in good organization. It is essential to plan the layout of aisles, storage areas and accesses.
Layout design
Aisles of adequate width: Facilitate the transit of people and equipment (forklifts, pallet trucks).
Separation of areas: Delimit areas for picking, storage, reception and dispatch, avoiding interference.
Logical flow: Design routes that reduce unnecessary travel and optimize the collection sequence.
Product location (slotting)
Categorization by rotation: Locate the products with the highest demand in areas of easy access.
Grouping by affinity: Place complementary products or those that are usually sold together in nearby areas.
Periodic rotation: Adjust the location of products according to seasonality or sales trends.
Picking methods
Selecting the appropriate picking method can make a big difference in warehouse performance.
Wave picking
Order batch planning: Orders that share shipping characteristics or picking zones are grouped together.
Optimizes time: Orders can be prepared and sent in waves, which speeds up dispatch.
Zone picking
Assigning zones to each operator: Each employee is responsible for a specific section of the warehouse.
Reduced travel: Operators are prevented from traveling throughout the warehouse to fulfill a single order.
Batch picking
Simultaneous order picking: Several orders are gathered at the same time to collect the same or similar products in a single trip.
Greater efficiency: The time spent moving an item several times for different orders is minimized.
Picking optimization technologies
Technological solutions can automate and streamline processes, helping to achieve higher levels of efficiency and accuracy. Warehouse management systems (WMS)
Real-time inventory control: Allows the exact location of each product to be known.
Route optimization: Suggests logical picking routes based on demand and inventory.
Mobile devices (handhelds, voice picking)
Real-time guidance: The operator receives precise instructions on what product to pick and where to locate it.
Error reduction: Scanners and voice confirmation minimize the possibility of confusion and incorrect readings.
Automatic picking systems (pick-to-light, robots)
Visual indications: Through lights or panels, the system guides the operator on the exact location of the product.
Advanced automation: Robots that can perform picking without human intervention, especially in high-volume environments.
Key performance indicators (KPIs) in picking
To evaluate the effectiveness of the implemented strategies, it is essential to measure and analyze key performance indicators.
Picking accuracy rate
Reflects the percentage of order lines picked correctly on the first attempt. High accuracy indicates a reliable system and well-trained staff.
Picking cycle time
It measures how long it takes from the start of picking an order until it is ready for shipment. The lower this indicator is, the faster the logistics process will be.
Cost per order line
Represents the average cost of picking each order line. Including labor, equipment, and technology helps determine the profitability of picking operations.
Best practices for picking optimization
In addition to the strategies and technologies mentioned above, there are good practices that strengthen results and improve the overall performance of the operation.
Staff training
Continuous training: Regularly update the team on new technologies and working methods.
Standardized procedures: Instruct operators in clear processes to reduce errors and delays.
Motivation and commitment: Involve staff in continuous improvement to encourage productivity and innovation.
Ergonomics in the picking area
Shelf height: Ensures that the most frequently moved products are within reach of the operators without forcing them into awkward positions.
Support equipment: Transport carts, conveyor belts and lifts to minimise excessive physical effort.
Lighting and signage: A well-lit and signposted workspace reduces errors and accidents.
Preventive maintenance of equipment
Periodic inspections: Ensure the correct operation of forklifts, conveyor belts and picking systems.
Failure prevention: Avoid unplanned stops that interrupt operations and generate additional costs.
Extended useful life: Keeping equipment in good condition prolongs its durability and efficiency.
Picking optimization is a continuous process that requires the combination of technology, organization and human talent development. By implementing appropriate strategies and measuring results through key indicators, companies can increase the efficiency of their operations and improve their customers’ experience. With a proactive approach and the adoption of best practices, picking becomes a strategic factor for competitiveness and success in today’s market.
