How Long Before Your Models Go Stale?
Drift Time Stats by Industry. The clock starts ticking the moment you deploy that shiny new ML model.
Here are model drift patterns across industries, and the numbers tell a sobering story. Your carefully trained algorithms don't age like fine wine—they decay like produce left in the sun.
The Drift Reality Check
Financial Services: 3-6 months
Credit scoring and fraud detection models face the fastest degradation. Market volatility and evolving fraud tactics mean your model's accuracy drops by 15-20% within a quarter.
Healthcare: 6-12 months
Diagnostic models hold up longer, but patient demographics and treatment protocols shift continuously. Expect performance drops of 10-15% annually.
E-commerce: 2-4 months
Consumer behavior changes with seasons, trends, and economic conditions. Recommendation engines lose 25% effectiveness within months without retraining.
Manufacturing: 8-15 months
Equipment and process models enjoy longer lifespans due to relatively stable operating conditions. However, equipment aging and maintenance changes gradually erode accuracy.⁴
Retail: 3-8 months
Demand forecasting models struggle with shifting consumer preferences and market dynamics. Inventory optimization algorithms typically need quarterly updates.⁵
Cybersecurity: 1-3 months
Threat detection models face the harshest environment. New attack vectors emerge constantly, making security models obsolete faster than any other domain.⁶
Most organizations still treat model deployment like software releases—build once, deploy, and forget. But your models are living systems that need constant care.
The companies winning the AI game aren't those with the best initial models. They're the ones with the best model monitoring and retraining pipelines.
How often are you checking your model's pulse?
