# Performing an Anomaly Assessment

> [!NOTE]
> **This page in the Handbook describes how to perform an Anomaly Assessment in IMS.**

Anomaly Assessments are a structured approach to assessing the risk associated with an Anomaly.

The Risk evaluation for an Anomaly includes an assessment of *Unmitigated Risk*, or the risk before considering existing controls or barriers, and the *Mitigated Risk* which is intended to represent the risk after considering existing controls or barriers.

Unmitigated and Mitigated Risk is scored using a familiar Risk Assessment Matrix combining the Probability and Consequence of Failure.

## Managing and Creating Anomaly Assessments

Anomaly Assessments are managed in the **Assessment** section on the Anomaly Details Page. From there, you can either manage an existing Anomaly Assessment or Create a new revision Anomaly Assessment.

The Assessment Section contains a number of columns containing the information described in the table below:

| Field | Description |
| --- | --- |
| Revision Nr | Read-only. Starts at 0, increments with each new Assessment. |
| Date | Defaults to today. **Mandatory.** |
| Description | Free-text justification/notes. **Mandatory.** |
| Anomaly Response | The response selected for this revision (e.g. Monitor, Repair, Investigate, Other Response Needed, No Response Needed - the exact list is configurable). **Mandatory.** |
| Unmitigated Risk | Risk position before controls, selected from the Anomaly Risk Assessment matrix. Optional. |
| Unmitigated Risk Note | Free-text note on the unmitigated risk (max 250 characters). |
| Mitigated Risk | Risk position after controls. Cannot be set until Unmitigated Risk is saved, and cannot exceed it. Optional. |
| Mitigated Risk Note | Free-text note on the mitigated risk (max 250 characters). |
| Schedule Name / Schedule Status | Linked Schedule and its current status, auto-populated when a Schedule is linked via the Recommendation button or Add to Schedule. |
| ECH Name / ECH Approval Status | Linked ECH and its approval status, populated once the linked Schedule is credited. |
| Action Item Name / Title / State | Linked Action Item details, auto-populated when an Action Item is created via the Recommendation button. |
| Reviewed By / Reviewed Date | Populated when a reviewer signs off using the Review button. |
| Created By / Created Date | System-set on creation. |
| Modified By / Modified Date | System-set on last edit. |

### Manage an Existing Anomaly Assessment

#### Edit Anomaly Assessment Details

To edit the details of an Anomaly Assessment (Date, Description, Anomaly Response, etc.):

1. Navigate to an Anomaly’s Details Page.
2. Click the *Edit* button at the left hand and make any changes as required.
3. Click **Save.**

#### Manage or Change an Anomaly Assessment

To manage or change an existing Anomaly Assessment:

1. Navigate to an Anomaly’s Details Page.
2. Select a row corresponding to an Anomaly Assessment version.
3. Click on the *Unmitigated Risk* field to select a Risk from the Unmitigated Risk Matrix. Click **Save** to accept your selection. Enter an Unmitigated Risk Note, if desired.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/image-RCFUYMNK.png?sv=2026-02-06&spr=https&st=2026-10-28T21%3A54%3A49Z&se=2026-10-28T22%3A54%3A49Z&sr=c&sp=r&sig=Hc0QZKxxgPr0vJNqXnVSeevKiFNgcUEznf0MFd4BRY8%3D)

1. Click on the *Mitigiated Risk* field to select a Risk from the Mitigated Risk Matrix. Click **Save** to accept your selection. Enter a Mitigated Risk Note, if desired.

Your selected Unmitigated and Mitigated Risk Scores will be displayed in the Assessment Grid.

> [!WARNING]
> Notes
> 
> **Mitigated Risk can never exceed Unmitigated Risk:** If an invalid Risk is selected, you will not be able to save your changes.
> 
> **Auto-clear on downgrade:** If the Unmitigated Risk is later lowered below the saved Mitigated Risk, IMS automatically clears the Mitigated Risk selection and flags this to the user.

### Create a New Anomaly Assessment Revision

When conditions and risks associated with the Anomaly change, a new Anomaly Assessment Revision should be created.

To create a new Anomaly Assessment:

1. Navigate to an Anomaly’s Details Page.
2. Click **+** to add a new revision of the Anomaly Assessment.
3. Enter the Date, Description, and Anomaly Response for the new revision.
4. Click **Save** to save the new Revision of the Anomaly Assessment.

The new Revision will be shown in the Assessment grid with the Revision Number incremented by 1.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/image-FD5ORCOD.png?sv=2026-02-06&spr=https&st=2026-10-28T21%3A54%3A49Z&se=2026-10-28T22%3A54%3A49Z&sr=c&sp=r&sig=Hc0QZKxxgPr0vJNqXnVSeevKiFNgcUEznf0MFd4BRY8%3D)

Now you can proceed to assess the Unmitigated and Mitigated Risk, as described in [Manage or Change an Anomaly Assessment](/v410/docs/performing-an-anomaly-assessment#manage-or-change-an-anomaly-assessment).

### Linking an Existing Schedule

Click **Add to Schedule** to link to an existing eligible Schedule rather than creating a new one. The button lists only Schedules on the same Equipment that are not yet credited and are not of the DEFAULT inspection type. The button is disabled for the “No Response Needed” response.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/image-48LG1CF8.png?sv=2026-02-06&spr=https&st=2026-10-28T21%3A54%3A49Z&se=2026-10-28T22%3A54%3A49Z&sr=c&sp=r&sig=Hc0QZKxxgPr0vJNqXnVSeevKiFNgcUEznf0MFd4BRY8%3D)

### Reviewing an Assessment

Click **Review** to record yourself and the date as reviewer. Clicking Review on an already-reviewed row removes the reviewer. It does not overwrite with a second reviewer. The Review button is only shown to users with assessment update rights.

![](https://cdn.document360.io/e492a0e0-a4ba-4aca-8fc6-76b95f91fdf3/Images/Documentation/image-5PN1YWGP.png?sv=2026-02-06&spr=https&st=2026-10-28T21%3A54%3A49Z&se=2026-10-28T22%3A54%3A49Z&sr=c&sp=r&sig=Hc0QZKxxgPr0vJNqXnVSeevKiFNgcUEznf0MFd4BRY8%3D)

> [!NOTE]
> Note
> 
> When an Assessment that has already been reviewed gets edited, the **Reviewed By** and **Review Date** fields are cleared automatically, indicating that no review of the updated Assessment has been completed.

### Using the Recommendation Button

With an Assessment row selected, click **Recommendation** to raise the matching follow-up:

| Anomaly Response | Recommended Action |
| --- | --- |
| Monitor | Create Inspection Schedule |
| Repair | Create CAIR Schedule |
| Investigate | Create Action Item |
| Other Response Needed | Create Action Item |
| No Response Needed | Button disabled |

When one action has been raised and resolved, the button shows that action’s name. When several apply, it shows *Recommended Action (N)* with a selector.

> [!NOTE]
> Note
> 
> Anomaly Responses and Recommended Actions can be configured using the [Anomaly Response Settings](/v410/docs/anomaly-response-configuration-administrator#anomaly-response-settings).

## Risk Matrix Configuration

The Risk Matrix used for assessing Unmitigated and Mitigated Risk is configured on a Site by Site basis. To customize the Risk Matrix for your Site, contact [User Support](/v410/docs/requestingsupport).

> [!NOTE]
> Note
> 
> Each risk selection is stamped with the Risk Matrix’s configuration at the time of selection. If the underlying Risk Matrix changes afterward, the Assessment is flagged as out of sync so the risk position can be re-confirmed. Existing ratings are never auto-changed.
