 This script provides you the list of active sites in your tenant with their administrator and usage in MB.
 
+## Why It Matters / Real-World Scenario
+
+In many Microsoft 365 tenants, SharePoint sites can quickly grow in number, with varying levels of administrative access and external sharing. Without visibility, it’s easy for unused or inactive sites to remain accessible, or for administrators to have unnecessary access to sensitive content.
+
+For example, an organization may have hundreds of departmental and project sites, some of which have never been used or have files shared externally. Security and compliance teams need to know:
+- Which sites have active administrators.
+- Which sites have sensitive data shared externally.
+- How recently sites have been used.
+- The age of sites for lifecycle and archiving decisions.
+
+This script addresses these challenges by providing a single, comprehensive report. It allows administrators to identify inactive or outdated sites, review external sharing risks, and ensure that administrative permissions are appropriate. The insights generated help enforce least-privilege access, improve governance, and support compliance audits across the tenant.
