Tier 3 — Workflow Operator (Summary)
Definition
Tier 3 Workflow Operator is the first tier where AI executes workflow steps autonomously within a clearly bounded scope. The AI performs pre-approved operational actions (file, route, classify, schedule, update state) without per-step human approval. Human oversight is post hoc and sample-based, and all actions must be reversible.
What Makes a Capability Tier 3
A capability is Tier 3 when all of the following are true:
- No per-step human gating
- Steps are pre-approved at intake.
- The AI executes named workflow steps directly as part of the production workflow.
- Bounded action authority
- The Risk Register entry specifies exactly what the AI may do (e.g., classify, route, file, schedule, update status) and under which boundary conditions (jurisdiction, audience, matter type, materiality thresholds).
- Post hoc, sample-based review
- Humans do not review every action.
- A defined sample of actions is reviewed against a rubric, with sampling rate tied to risk class.
- Reversible or recoverable actions
- Every AI action can be unwound or corrected by a human.
- There is a documented path to reversal with named owners and time expectations.
Tier 3 is not just “more Tier 2.” It is a different operating mode: from human-with-tool (Tier 2) to tool-with-supervision (Tier 3).
