A specification is a collection of rules to apply during a project quality execution. The rules are grouped by a theme or a topic and executed to examine the quality of a Talend project.

The Specifications tab displays a list of all the specifications created for project quality checks.

A specification contains a set of rules grouped by a theme or a topic. You can expand each specification which contains a set of rules belonging to the specification.

Qlik Talend Cloud Migration Toolkit has already created a predefined set of rules and specifications.![In the Specifications tab, a specification is expanded.](https://help.qlik.com/Resources/Images/qlik-talend-cloud-migration-toolkit-user-guide/tcmp-ui-specifications.png)
