For an organization of that size, I focus on architecture and governance first, as visuals could be worked on later.
I would start with a centralized, shared dataset approach. Instead of every department building its own model, I'd create a certified semantic model in Power BI Service that acts as the single source of truth. Department-specific reports would connect to this dataset using Live Connection or thin reports. That avoids duplication and inconsistent metric definitions.
For security, I would implement dynamic Row Level Security using a security mapping table. With 500+ users, static roles don't scale. A mapping table that links UserEmail to Department, Region, or Access Level allows security to be managed by adding rows, not modifying the model.
Workspace strategy is equally important. I would create separate workspaces for each department, for example, Finance, Sales, and HR, with clearly defined roles such as Admin, Member, and Viewer. This keeps development isolated while still using centralized datasets.
For governance, I would use deployment pipelines to manage Dev -> Test -> Prod transitions. Naming conventions for datasets and reports reduce confusion. I would also certify or endorse verified datasets so users know which ones are approved for reporting.
Capacity planning matters at this scale. For 500+ users, I would evaluate Premium capacity (P1/P2) or Premium Per User depending on concurrency and refresh needs. Pro-only environments may struggle under heavy usage.
I would distribute reports through Power BI Apps so each department gets a clean, curated experience with a single access point.
To monitor adoption, I would use usage metrics reports to track which dashboards are actively used and identify unused assets for cleanup.
At the tenant level, I would configure governance settings carefully, controlling who can publish, share externally, export data, or create new workspaces.
Finally, I would rely on the data lineage view to understand upstream dependencies. If a central dataset changes, I can quickly assess which reports and departments are affected.
