+# ServiceNow Background Script – Identify Inactive Assignment Groups

+## Overview
+This background script identifies **assignment groups that have no active members**.  
+Such groups can cause issues with **incident routing**, **task assignment**, or **notification delivery**, since tickets assigned to these groups may never reach an active user.
