In today’s era of artificial intelligence, it is increasingly tempting to pursue models that deliver the highest possible statistical performance—often at the cost of transparency. Many of today’s most powerful AI systems are “black box” models: while they can produce highly accurate predictions, the logic behind their decisions is largely opaque, even to their designers. This creates serious challenges for trust, accountability and real-world decision making. Explainable AI (xAI) addresses this problem by developing models and tools that not only predict outcomes, but also clearly communicate why those predictions are made. In demand forecasting, for example, a black box model may accurately predict next month’s sales but provide no insight into whether the driver is price, seasonality, geography, inventory constraints or promotions—leaving managers with little guidance for action.
Now consider a simple but consequential question: if you are a supply chain manager preparing for the next quarter, which is more useful—an opaque model that outputs a single forecast number, or an interpretable model that shows how price changes, regional trends, warehouse flows and seasonal effects collectively shape demand? That exact tension motivated xLab’s collaboration this semester with a global manufacturing company to modernize its demand forecasting process using explainable AI. Student teams worked closely with industry partners to rebuild forecasting pipelines using interpretable machine learning models, engineering features that captured seasonality, pricing, regional distribution patterns and warehouse logistics. Instead of delivering predictions alone, the models revealed the economic and operational forces underneath those predictions.
The results reshaped how forecasts were used. With explainable models, managers could not only anticipate demand, but also identify which operational levers—pricing strategies, regional inventory positioning and distribution flows—were most responsible for projected changes. Strong predictive performance mattered, but it was the transparency of the models that made the forecasts actionable. For students, the project offered a powerful lesson in applied data science: technical accuracy creates potential, but interpretability creates adoption.
The value of explainable AI extends well beyond demand forecasting. In finance, it shapes how credit risk is evaluated; in healthcare, how diagnoses and resource allocation are justified; in marketing, how customer targeting decisions are defended; and in operations, how efficiency gains are understood and sustained. Across these settings, leaders and data science practitioners face the same responsibility—to ensure that models do more than produce predictions, and instead generate understanding. That responsibility is where technical rigor meets human judgment. xLab exists to help bridge that gap.
