+Overview
+
+This script calculates the SLA breach percentage for each assignment group based on closed incidents in ServiceNow.
+It leverages GlideAggregate to count both total SLAs and breached SLAs efficiently, providing key SLA performance insights.
+
+Useful for:
+	•	SLA dashboards
+	•	Support performance tracking
+	•	Service improvement reports
+
+Objective
+
+To determine, for each assignment group:
+	•	How many SLAs were closed
+	•	How many of those breached
+	•	The resulting SLA compliance percentage
+
+Script Logic
+	1.	Query the task_sla table.
+	2.	Filter for closed SLAs linked to incidents.
+	3.	Aggregate total SLAs (COUNT) and breached SLAs (COUNT, 'breach', 'true').
+	4.	Group results by assignment group.
+	5.	Calculate breach percentage.
