System Behavior

Behavioral Drift

Behavioral drift occurs when a system's actual behavior gradually diverges from its expected behavior over time.

Definition

Behavioral drift occurs when a system's operational behavior gradually diverges from its intended design. This can result from configuration changes, evolving workflows, or changing data inputs.

Why It Matters

Automated systems often evolve without a single major change event. Over time, small shifts can make a system behave in ways that are no longer predictable or aligned with policy.

Example

A workflow originally designed to update internal tickets slowly expands to interact with external SaaS tools after several integration changes.
