Model Monitoring & Observability
Model Monitoring & Observability is the practice of continuously tracking the behavior of machine learning models after they are deployed to production. It covers detecting data drift, concept drift, model performance degradation, data quality issues, and silent failures that do not produce system errors but yield wrong predictions. Observability goes a step further than monitoring by providing the tools and instrumentation to diagnose why a model is misbehaving, not just that something went wrong.
As ML systems move from experiments to business-critical infrastructure, teams need confidence that models keep performing as expected under real-world, shifting data distributions. Regulators under frameworks like the EU AI Act increasingly require auditability and continuous validation of high-risk AI systems, making observability a compliance requirement, not just a best practice. Companies hire specialists in this area because undetected model failures translate directly into bad product decisions, financial losses, or reputational damage.
