Our advanced machine learning (ML) based demand forecasting engine is a key pillar and a foundational element of Legion’s Workforce Management (WFM) platform. Legion’s ML-based demand forecasting has several advantages over other approaches:

  • Learns more subtle patterns
  • Incorporates different types of data
  • Scales and produces consistent and accurate forecasts week over week for hundreds of thousands of data sets.

There are a lot of claims around accuracy, but what exactly is an accurate forecast? And why does the way you report and measure it matter? It’s easy to measure accuracy – you get a forecast, wait for the actuals to come in, then compute the difference, and perhaps you express the difference as a percentage. That’s the easy part.

But, it leaves many open questions:

  • Over what time period should you measure?
  • If you have many data sets, how do you aggregate the results?
  • And most importantly, if you have a number representing accuracy, how do you know if it’s good or bad?

Read our latest white paper, Achieve New Levels of Accuracy with Legion Demand Forecasting, which provides insights about demand forecasting approaches and best practices. It describes how Legion WFM applies answers to the questions above and how we measure and report the accuracy of our demand forecasts.
