High-Level vs. SKU-Level Forecasting

Understanding SKU Demand Changes

Recent data reveals that warehouse costs have climbed by 12% as consumer spending has dropped, underscoring the importance of effectively managing demand fluctuations.

What Makes SKU Demand Change

The ups and downs of SKU demand are influenced by interconnected factors like seasonal trends, promotional campaigns, and shifts in the market. A striking example is the recent semiconductor shortage, where an unexpected surge in orders from device manufacturers created a domino effect throughout the supply chain. This overwhelmed chip foundries and disrupted standard supply patterns.

One concept that vividly illustrates this is the bullwhip effect. Professor Jason Miller from Michigan State University explains it as follows:
"The bullwhip effect is the idea that the variance in orders becomes amplified as you move upstream in the supply chain…from retailer to wholesaler, wholesaler to manufacturer, and so on."

To manage these fluctuations effectively, businesses need to rely on specific metrics to monitor and understand demand changes.

How to Measure Demand Changes

Tracking demand variability requires businesses to focus on key metrics, each offering unique insights into inventory and operational efficiency:

Business strategist Nicolas Babin underscores the importance of these metrics:

"Demand variability significantly impacts inventory levels. When demand fluctuates unpredictably, companies might either hold excessive stock, leading to increased holding costs and potential obsolescence, or face stockouts, resulting in missed sales and eroded customer trust."

Limits of Basic Forecasting

Even with their advantages, traditional forecasting methods have their limitations. These techniques, which often combine expert judgment with statistical models, struggle when demand patterns become overly complex. A major drawback is their inability to simultaneously process multiple variables. As industry research points out:
"Unless you have a system that simultaneously acts on historical data, customer demand and industry trends, you can end up making significant costs from overstocking and storage."

However, companies adopting advanced forecasting tools have seen measurable benefits. For example, businesses using automated data capture systems reported a 20% reduction in excess inventory and a 15% improvement in order accuracy by aligning more closely with real-time demand signals.

Getting Data Ready for AI Analysis

Did you know that data practitioners spend as much as 80% of their time on data preprocessing and management tasks? That’s a massive chunk of time dedicated to preparing data before AI can even begin its analysis. But this effort is essential - especially when tackling SKU demand variability. Clean, well-prepared data is the backbone of any successful AI-driven analysis.

Required Data Types

For AI to accurately analyze SKU demand, businesses need to gather data from a variety of sources. Here's a breakdown of the key data categories and what they should include:
