What it adds

</th></tr></thead><tbody><tr><td>

Product Model

</td><td>

com.sn\_prd\_pm

</td><td>

Adds characteristics on test definitions and test groups, characteristic mapping, test decomposition rules, test group characteristic runs, and the **Specification** field on a test group relationship.

 Without this plugin, a test group relationship uses a product model only.

</td></tr><tr><td>

Product Inventory

</td><td>

com.sn\_prd\_invt

</td><td>

Adds the **Product inventory table** and **Conditions** fields on a test group relationship, so that a test group applies only to product inventory records that meet the conditions.

</table>## Relationship with Customer Service Problem Management

You can install Service Test Management without Customer Service Problem Management \(CSPM\). CSPM requires Service Test Management.

CSPM provides the API that external systems use to send test runs, test measures, threshold rule violations, and applied consequences. For details, see [Related Customer Service Problem Management information](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/australia/markdown/australia/telecom-media-technology/stm-related-cspm-information.md).
