# Step 11 Review Results – NID, MII, IS, Inspection Effectiveness

## ![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/SRBI%20(7).jpg?sv=2026-02-06&spr=https&st=2026-10-28T11%3A54%3A21Z&se=2026-10-28T12%3A54%3A21Z&sr=c&sp=r&sig=1AB3IB42u0VQDBI4gqEiDL0Kr2oWIzjReDftFduSMKI%3D)

## Aim

The S-RBI deliverables are:

- A Next Inspection Date (NID) – mainly for AR DMs.
- An Inspection Strategy (IS) and sometimes Maximum Inspection Interval (MII) – for NAR DMs.
- A required Inspection Effectiveness* [](/docs/step-11-review-the-results-nid-mii-is-inspection-effectiveness#footnote-4)– for AR DMs. The user can use the S-RBI results (Interval Factor (IF) and Remnant Life (RL)) to determine this. The required Inspection Effectiveness then in turn determines the required combination of Inspection technique and coverage.

*Note: According to API RP 581.

These 3 deliverables determine how and when to inspect, i.e., how to verify the Barriers, and should be reviewed and interpreted, before being assigned to an inspection in [Step 12](/v414/docs/step-12-assign-s-rbi-results-to-inspectioncorrosion-schedules-andor-update-monitoring-plan).

See [Methodology Step 11](/v414/docs/methodology-step-11) and [Software Step 11](/v414/docs/software-step-11).
