Slow Demand Inventory Mistakes Even Smart People Make

Is Managing Slow Demand this Painful for You?

Slow and Intermittent traffic is bad, worse is a snowstorm shutting down the highway leaving you stranded in your car for 10 hours. There is nothing worse than slow or dead stopped traffic in a snowstorm right? Maybe, while we sit in traffic, we should consider the slow demand products in your assortment.

Why Sales Forecasting Systems are Wrong for Inventory Replenishment

Sales Forecasting is the wrong tool for inventory replenishment and inventory planning. Sales Forecasting, by its very name itself, is a measure of total sales. In our last article, we discussed that the key difference between sales forecasting and demand forecasting is whether (or not) sales data is broken out into the type of sale, analyzed, and the results input into the forecasting algorithms. Sales type might include any or all of the following: regular, lost, promo, event, and closeout sales. Without the knowledge that sales went up or down due to market factors like out of stock and promotions, a sales forecasting system will forecast based only on the total sales. This may not be the intended goal for inventory replenishment or inventory management.

Key Limitations to Sales Forecasting

Sales Forecasting, by its very nature, doesn’t know why sales rise or fall and cannot connect events to sales behavior. For example, when sales were down 20% four weeks ago, you probably knew this was due to constrained supply which created out of stock issues. The sales forecasting system will react to the 20% drop by lowering the forecast. The resulting inventory replenishment orders from the new forecast will be low, creating a repeat scenario of lost sales again next month.

Proof: Improving Forecast Accuracy delivers High ROI

A mountain of research today shows that improving forecast accuracy delivers a high ROI. Improved forecast accuracy, when combined with software that translates the forecast into demand-driven events, will decrease inventory and operating cost, increase service and sales, improve cash flow and GMROI, and increase pre-tax profitability.

Lowering Inventory and Raising Sales at the Same Time

Many people are conditioned to accept mediocre demand forecasting accuracy. The most common excuses I hear for keeping inaccurate forecasting include: “We paid a lot of money for the software” and “The software does a good job with other operations.” The irony is that the same people when asked if they shopped for better software, will respond no. The explanations range from they do not see the value to disbelief – there isn’t a better demand forecasting solution in their market. Businesses have reacted for the last 20 years by placing more value on the plan, a top-down approach that costs more money and has lower returns.
