How often do industrial models need retraining?

Trigger-based beats calendar-based: retrain on detected drift, product introductions, or instrumentation changes. Mature platforms automate the detection and make the retrain a reviewed, versioned event rather than a silent overwrite.

Do we need an MLOps team to buy an ML platform?

No — that's the platform generation's core promise. You need someone accountable for acting on model-health signals, the way someone is accountable for calibration. Building custom models in-house is a different decision that does require the engineering bench.

MLOps (industrial)

Key takeaways

Factory models degrade by default: materials, tools, seasons and product mixes shift the data underneath them.
Industrial MLOps is the discipline of keeping models honest — drift monitoring, retraining, versioning, and regime updates.
In platform buying, MLOps should be invisible: the vendor's problem, surfaced as health indicators, not your new engineering discipline.
The buyer's question is not 'do you have MLOps' but 'what happens, concretely, when my line changes products or a sensor is recalibrated?'

A model trained on last year's line is a model of last year's line. Tools wear, suppliers change, a sensor gets recalibrated, a new product joins the mix — and the learned “normal” quietly stops being normal. Unmanaged, this produces the second-year failure pattern: a system that was sharp at deployment and is politely ignored eighteen months later.

What the discipline covers

Drift monitoring: watching whether live data still resembles training data, and whether model performance (precision of alerts, accuracy of estimates) is decaying. Retraining: scheduled or triggered refreshes that incorporate recent history without swallowing recent anomalies as “normal.” Versioning and rollback: knowing which model made which call — increasingly an audit requirement. Regime management: telling the system about planned changes (new product, maintenance events) so it adapts deliberately rather than learning accidents.

The buyer's translation

For a plant buying platforms (rather than building models), MLOps should be the vendor's problem, visible to you as model-health indicators and a clean answer to concrete questions: What happens when we introduce a product? Who approves a retrain? Can we see why this month's model flags differently than last month's? Vendors with real answers have operational maturity; vendors who answer with algorithm names do not.
