| **Channel**                | The entry Node of a Workflow that defines the delivery medium (Email, Web, Mobile, Landing Page).                 |
| **Branch**                 | A unique execution path through a Workflow, from a Channel to an Output Node.                                     |

| **Non-Exposed Population** | The group (typically 10%) who see default content without Reelevant personalisation, used as baseline for measuring Incremental Value.                                         |
| **Uplift**                 | The incremental performance gain from personalised content compared to default content.                                                                                        |
