What Is Demand Sensing and Why Supply Chain Executives Need to Know More
Understanding more about the needs and wants of customers can help supply chain leaders make informed decisions, improve inventory management, and increase profitability. In recent months, conversations about how to improve forecasting in the supply chain have focused on a subject: demand sensing. However, what is demand sensing? In its most basic sense, it’s about sensing demand based on variables in supply and demand, but that’s only half the concept. The remainder lies in understanding what demand sensing means for current supply chain and inventory management operations and how to utilize demand sensing best.
Deficiencies in the Supply Chain Derive From Inaccurate, Poor Forecasting
Methods
Failures in the supply chain derive from problems in supply and demand management. Peaks and lulls in consumer orders result in longer shelf-life for products in warehouses. During peaks, demand is so high that the company may run out of stock, and items are back ordered. Unfortunately, a cause for increased lead time for products is a result from over-ordering, so in this back and forth situation, carrying costs continue unchecked. While long-term forecasting is still crucial to supply chain management, supply chain leaders need a way to refine the short-term forecast, within 56 days, to reflect the realistic demand of products. At the same time, millions of SKUs, thousands of vendors, and globalization have made manual inventory tracking and forecasting obsolescent. This is where demand sensing comes into play.
Demand Sensing Leverages New Methodologies and Data to Enhance Models
Demand sensing automates the process and leverages new
technologies, including automation in the
warehouse, to achieve speed and accuracy in forecasts, resulting in
decreased lead time. According to Arindam
Sen of HD Tech, demand sensing refers to the use of mathematics and
real-time data to calculate forecasts with greater accuracy. In other words,
it’s a concept similar to the application of analytics to understand what products
customers want, but demand sensing is based on supply and demand variability.
Instead of traditional demand forecasting, demand sensing goes back to using
updated data to create more accurate, short-term forecasts. These forecasts
apply to purchase and procurement, so the warehouse can restock and reorder
products to meet consumer demand. This helps enterprises manage the effects of
fluctuation without sacrificing long-term success and plans.
Applied in conjunction with inventory and slotting optimization, companies can move toward a just-in-time inventory management model. This effectively lowers carrying costs and enhances the responsiveness of the supply chain. Of course, supply chain leaders still need to know to put the power of demand sensing to work in the modern supply chain.
How to Go From “What
Is Demand Sensing” to “How Can I Take Advantage of Demand Sensing”
Many arguments have been made that the value of demand
sensing makes it less opportunistic than other improvements in the supply chain.
Unfortunately, that concept is nothing shy of a dominant myth, and retail
giants, like Nike, have successfully leveraged demand sensing to cut lead times
by half and achieve double-digit growth, notes Emma
Cosgrove of Supply Chain Dive. Nike’s version of demand sensing uses
rapid prototyping and connected systems, leveraging real-time data, to refine
replenishment and increase flexibility in the supply chain. Executives can
learn from Nike’s example by following these key steps:
- Integrate your WMS with other supply chain
systems. - Collect real-time data from all operations and
channels. - Focus on product lead-time.
- Know the basics of demand sensing, including
automated, real-time forecasting and continuous refinement of forecasts, in
vetting vendors that offer demand sensing. - Work with suppliers and vendors to collect data
and streamline replenishment activities.
Put the Power of Demand Sensing in Your Supply Chain to Work
Demand sensing is a term that predates analytics, but it is
an invaluable resource and way of managing inventory, mainly replenishment, in
supply chains. Executives need to leverage technology and software to use
demand sensing to drive lead times down and move other inventory optimization
processes into the 21st century.
