    How A DC Walkthrough Can Improve the Inventory Control Workflow

    How A DC Walkthrough Can Improve the Inventory Control Workflow

    A DC Walkthrough is an engaging assessment that includes discussions, observations, and interviews among workers, supervisors, and management personnel with the objective to document current business and operational processes and look at ways technology and process changes can be applied to make improvements. The DC Walkthrough can be an informal or formal review/audit conducted by the company or external third parties. 

     

    At Honeywell we have the opportunity to conduct DC Walkthroughs throughout the world for every conceivable type and size of DC. The goal of our assessment is to validate logistical/operational processes relative to industry best practices focused on time savings, increased worker productivity, and improved accuracy. We focus on the identification of opportunities to both improve stand-alone general processes, as well as improve processes with new technology. 

    When we review the Inventory Control workflow, we ask questions like:

    1. Is cycle counting performed in the DC?
    2. When are cycle counts performed?
    3. Are cycle counts interleaved with other work processes?
    4. What tools are used for cycle counts? (paper, RF, voice)
    5. How are the products/locations determined for cycle counting? (scheduled, random, ABC classification)
    6. Can cycle counts be requested for specific items/locations? If so, how is this communicated?
    7. What steps are taken if a discrepancy is discovered?
    8. What changes are desired in the cycle-count process?
    9. How often is a physical inventory taken?
    10. What is the physical process?
    11. Is it a blind count?

    Inventory Control Walkthrough Observations and Recommendations Example

    Conducting a DC Walkthrough is done with “fresh eyes.” Fresh eyes is defined as looking at the workflow with the intent of learning and understanding the current state of operations without bias or preconceived conclusions, and then applying industry knowledge and best practices to recommend ways to improve upon the current performance.

    The following is an example of a DC Walkthrough Honeywell did for a medium-sized DC in North America for the Inventory Control workflow, which includes observations with associated recommendations.

    DC Walkthrough Observations

    1. Doing physical inventories
      1. Cost is about $750K annually
    2. Location utilization is high
      1. Cube utilization is not as efficient
    3. 85% of inventory is similar across 3 NA DCs
    4. Issues with master carton being labeled correctly but material inside carton wrong
      1. So, is Master carton really labeled correctly, then?
    5. Overstock area has dog items
      1. Some have not moved in years
      2. Carrying cost has now exceeded any revenue gained

    DC Walkthrough Best Practices Recommendations

    Inventory control practices in a DC are vital to the accuracy of the overall inventory. This accuracy is monitored closely by both internal and external auditors as the accuracy is paramount to properly valuating the inventory contained in your supply chain network.

    We recommend using a RF cycle-count process as it should be supported by the WMS. Use any WMS functionality that supports interleaving the process with fork moves or picking where possible. By interleaving the processes, you can count exceptions as they occur and count slots that drop below a certain level once retrieval from a location is made (i.e., less than 3 or 5). By only counting those slots with little inventory you are not negatively impacting the operator’s productivity and you are making the process more proactive vs. reactive. The WMS should also support live cycle counting without the need to shut down an aisle while counting.

    If using voice for picking, Honeywell Voice provides an interleaved picking and cycle-count process that provides greater productivity and accuracy in this workflow.

    We also recommend utilizing any ABCD functionality in the WMS, which focuses on your fastest movers being counted more often and by default maintains a more accurate overall inventory. Most WMS systems also support Value-Based cycle counting of higher-priced items.

    We recommend working with the auditors to prove the cycle-count process accuracies and eliminate the physical inventories. Not only are they costly to perform and costly to the business (the need to halt operations results in being behind in fulfillment), but they can introduce inaccuracy with poor counts.

    We noticed that location utilization is high but cube utilization is not ideal in some areas. We know there is a current effort to address this with TI x HI audits and adding additional levels of racking to some areas to create smaller height locations for those items. This a great initiative and should be carried forward aggressively.  

    Some items in the DC have not moved in years and should be eliminated as judiciously as possible. Industry averages show that carrying costs for inventory can be as high as 3%, so if this product has not moved in years the cost of carrying it this long has already eroded the revenue it would create now.

    Recommended hardware and software for these processes includes:

    All recommendations are Android™ capable.

    Technology Improvements in the Inventory Control Workflow

    According to the 2018 WERC study1, technology within the supply chain is becoming increasingly important. Many companies are beginning to focus on digital transformation by focusing more on mobile technologies, cloud-based services, and big data practices. 

    The study also points out that a majority of distribution centers use no other technology beyond a warehouse management system (WMS) and mobile devices with RF/barcode scanners. In terms of adoption plans, over 90% of warehouse managers expect to be using mobile technologies within five years (which is just over 50% today). Eighty-six percent expect to be using big data and real-time analytics within five years, which is a 60% increase over the percentage of people using the technology today.

    Honeywell brings a wide set of solutions together that can influence positive outcomes in the Inventory Control workflow throughout the DC. They include the following:  

    • Mobile Computers with 1D and 2D Imaging. Utilizing mobile computers with imagers to scan product and label information as well as capture additional data is more productive (~25%) and accurate (~50%) than paper/manual-based methods. It helps ensure quality control, vendor compliance, and quantity-received information is captured in real-time.
    • Wearable Solutions. A growing number of companies have turned to hands-free computing solutions to streamline operations and improve productivity. The Honeywell 8680i wearable mini mobile provides a hands-free solution that offers increases in productivity and improved ergonomics over handheld devices.
