Objective: I need a Power BI dashboard built from an Excel dataset that tracks Zero Trust capabilities across multiple cybersecurity pillars (e.g., Identity, Device, Application, Data, Network, Automation, and Visibility). The dashboard should allow interactive filtering, maturity level tracking, and referencing key data points.

Deliverables:
Power BI report with visual dashboards
Clean and normalized dataset from provided Excel file
Interactive visuals that support filtering by:
Capability Pillar (User, Device, etc.)
Maturity Level (Basic, Intermediate, Advanced)
KPI Targets and Status (Met/Unmet)
Fiscal Quarter and Phase
Data model including fact table + dimension tables

Visuals like:
Maturity distribution by pillar (donut/bar)
KPI compliance tracker (status cards or gauges)
Phase-based roadmap or timeline
Drill-through capabilities to view detailed capability info
Documentation or short video walkthrough of functionality
