Role of WMS in Streamlining Processes

As already clear, warehouse management systems are key to ensuring every step involved in warehouse management is seamless. 

Below is the list of 8 critical warehouse management processes and how WMS can help make them efficient. 

1. Reception of products + quality inspection

This step involves the acceptance and verification of the goods that your vendor or supplier sends. You can check the items you receive against your purchase orders to ensure their quantity and quality are as requested. Following that, you label and document each product in your inventory. Relying on a manual approach like using pen and paper for all this may be time-consuming and error-prone. 

However, a WMS solution can help you define business rules and warehouse flow to receive, process, and transport goods to your designated storage area. It provides the Radio Frequency Identification Technology (RFID) and allows for integration with billing software. This helps automate the reception, validation, and reconciliation of received goods against digital purchase orders using barcode scanning. It also helps auto-generate labels for easy storage and retrieval of your products.

2. Order picking and packing

Picking is the process of selecting and gathering items from your warehouse inventory to fulfill orders. It can be of various types as follows:

• Piece picking: Also known as single-order picking, this method involves picking items to fulfill a single customer order at a time. It is suitable if your warehouse is small and order volume is low so that pickers can navigate your entire warehouse easily to pick desired items. 
• Batch picking: Using this method, you can select items to fulfill multiple orders simultaneously. You can then sort the picked items into individual orders. 
• Cluster picking: This method lets you pick items for multiple orders at the same time but sort them into individual orders at their pick location instead of a central sorting facility, unlike in batch picking.
• Zone picking: It involves dividing your warehouse into multiple zones and assigning a specific zone to each picker to select items from. It is generally suitable if your warehouse is large with a vast range of items. 
• Discrete order picking: It involves assigning particular orders to individual pickers, who then pick the items to fulfill those orders accordingly. Once the picking is complete, you can consolidate items for packing. 
• Wave packing: It involves grouping multiple orders into waves. Each wave represents a set of orders that you can pick simultaneously, often at specific times of the day and in short intervals. 

Once you pick your order, packing follows. It refers to placing items in appropriate packaging, including bins, containers, or polybags, based on their type to prepare them for shipping. 

WMS can help you store, retrieve, and pack products efficiently. In addition to enabling standard picking methods discussed above, it supports advanced picking technologies. These can include Radio Frequency (RF) with or without scanning verification, pick-to-voice or pick-to-light technology, robotics, automation, and algorithms to optimize picking paths.

3. Shipping 

Shipping means loading packaged goods onto vehicles to transport them to your customers. During shipping orders, your packaging must be secure to prevent any in-transit breakage or damage. It is also crucial to optimize your package volume to reduce delivery costs. 

Warehouse management solutions can integrate with your logistics and delivery management software to expedite your fulfillment process. For instance, it can help automate the generation of bills of lading (BOL), packaging lists, invoices, and shipment notifications to your customers.

4. Labor management

Labor management entails planning, organizing, and optimizing your workforce involved in the day-to-day warehouse tasks like picking or packing. It can include estimating the right number of workers for each shift and creating schedules that align with their operational demands. 

Training and skill development, along with regular labor performance evaluation, are also an important part of it. 

A WMS can deliver valuable and actionable insights into different aspects of your labor. For example, it provides real-time visibility into your warehouse workers’ working hours, their costs, response times, and adherence to safety protocols. Moreover, WMS software enables you to combine different tasks like the movement of goods to storage areas and picking in a single trip. It reduces the time to execute them individually, increasing your overall warehouse efficiency.

5. Yard and Dock Management 

Yard and dock management is the process of managing and optimizing all the activities that occur in your yard or dock. It helps achieve a continuous outflow of goods in and out of your warehouse.

An advanced warehouse management solution provides yard and dock management features. It helps schedule appointments and assign a particular loading dock for your incoming and outgoing carriers or delivery drives based on priorities, product types, or vehicle weight. This helps cut down waiting time to access a dock, prevent congestion, and handle high-priority shipments promptly.

6. Inventory cycle counting 

Inventory cycle counting is an ongoing and systematic way of inventory management. It involves counting a subset of inventory items periodically to spot any gap between the actual physical count and recorded numbers. This identification of discrepancies contributes to their timely investigation and resolution before they disrupt warehouse operations drastically. 

Using warehouse management software, you can track your inventory items to know whether they are in your warehouse, store, or transit. WMS leverages Automatic Identification and Data Capture (AIDC) technology like barcodes or RFID to collect and enter data about items electronically and use it to track them. Some sophisticated software also facilitates cycle counting and generates reports on your product and vendor performance to forecast demand accurately. 

7. Reverse logistics management (returns, exchanges, repairs, recycling, replacements)

Reverse logistics constitutes all the activities involved in managing the flow of goods or materials from your customers to your warehouse. It can involve managing returns, replacements, exchanges, or disposition of obsolete inventory. 

Warehouse management software helps track the location and condition of returned items to facilitate informed decisions on how to handle them. For instance, it helps define rules and workflows to categorize returns for restocking, refurbishing, or recycling. It can also generate exhaustive reports on return reasons and trends. These insights facilitate data-driven decisions on how to improve your product quality and lower your return rates. 

8. Warehouse organization and performance reporting 

Warehouse organization (sometimes referred to as warehouse slotting) is the strategic organization and management of inventory goods in your warehouse. Warehouse performance analysis is defined as evaluating the efficiency, effectiveness, and overall productivity of your warehouse operations. It involves tracking key performance indicators (KPIs) like order fulfillment rate, average lead time, or return rate. Insights into these performance indicators help you know how well your warehouse is functioning and identify improvement areas.

WMS helps reduce manual efforts to track metrics like on-time shipping, inventory accuracy, distribution costs, order fill rate, or cycle time. Besides, a warehouse management tracking system can generate reports on people-related aspects, including staffing needs, certifications, and licenses required. It analyzes factors like stock-keeping-unit (SKU) velocity, size, and demand patterns to determine optimal storage locations, enhancing space utilization and hence, warehousing efficiency.

So, it is evident that every warehouse management process holds its own importance and contributes to efficient warehouse management.

Following are the tips to help you excel at your warehouse management.

1. Conduct ABC Analysis

Using ABC analysis to organize and classify your inventory is crucial for effective warehouse management. This method uses criteria like sales frequency and storage value to categorize items accordingly. Sales frequency is the average number of days it takes to sell a product, while storage value is the cost of storing it in your warehouse. 

You can classify all your goods into three categories, as below:

Category	Storage Value	Sales Frequency
A	High	Low
B	Moderate	Moderate
C	Low	High

For instance, if you are a grocery retailer and sell premium truffle-infused olive oil, it will fall into category A. On the other hand, table salt will fall in category C. 

Once you classify products like this, you can place high-demand products like table salt in easily accessible areas of your warehouse. On the contrary, you can keep olive oil at the back of your warehouse to minimize the impact of external factors and ensure it stays in optimal condition.

2. Keep your warehouse clean

Cleaning your warehouse regularly is essential to ensure hygiene, safety, and easy operations. So, you should plan a cleaning schedule for your warehouse that can be weekly or fortnightly as appropriate.
