Map your data sources – See where everything comes from and how it's connected
Trace visuals to logic – Understand what each tab or chart depends on
Prioritize – Start with the most critical section
Rebuild the logic – Reverse engineer everything into clean, centralized SQL
Simplify and optimize – Eliminate redundancy and improve performance
Rebuild the dashboard – Based on a cleaner, more sustainable foundation
