Frequently Asked Questions

What is Power BI and how can it help my organization?

Power BI is Microsoft's enterprise analytics platform that transforms raw data into interactive dashboards and reports. It enables data-driven decision-making across your organization with real-time insights, automated refresh, and role-based access control. EPC Group has delivered 200+ enterprise Power BI implementations.

How much does Power BI consulting cost?

Power BI consulting typically ranges from $50K-$250K depending on scope. A focused dashboard project runs $50K-$100K, while enterprise-wide analytics platforms with governance frameworks cost $150K-$250K. EPC Group provides detailed estimates after a free discovery session.

What industries does EPC Group serve with Power BI?

EPC Group delivers Power BI solutions across healthcare (HIPAA-compliant), financial services (SOC 2), government (FedRAMP/GCC), manufacturing, retail, education, energy, and professional services — all with industry-specific compliance and security configurations.

How long does a Power BI implementation take?

Timeline depends on complexity: a focused dashboard suite takes 4-8 weeks, a department-wide analytics rollout takes 8-16 weeks, and an enterprise platform with Fabric, governance, and training takes 4-6 months. EPC Group uses agile delivery with 2-week sprint cycles.

Power BI Strategy: 2026 Considerations for Resources Power BI Best Practices

Direct Lake mode has changed the economics of enterprise Power BI in 2026: instead of importing data into Vertipaq, semantic models now query OneLake-resident Parquet files at near-Import-mode performance without the refresh-window cost. For a Fortune 500 finance organization migrating from a 30-minute Import-mode refresh, the equivalent Direct Lake model typically queries fact data in under 800 ms while removing the entire refresh-orchestration job from Azure Data Factory.

Row-level security (RLS) and object-level security (OLS) in Power BI Premium and Fabric F-SKU capacities are the single most-overlooked compliance control in HIPAA, SOC 2, and FINRA-regulated environments. RLS scoped via service principal authentication (rather than embedded UPN passes) is the only pattern that survives a SOC 2 Type II auditor privilege-walk test. EPC Group includes service-principal RLS as a default in every regulated-industry Power BI engagement.

Decision factors EPC Group evaluates

Row-level security via service principal authentication
Capacity sizing decision (F2/F4/F64+) tied to peak concurrent users and refresh window
Copilot grounding quality assessment of semantic-model metadata
Direct Lake mode adoption for Fabric-resident semantic models
License optimization audit (Pro vs Premium Per User vs F-SKU)
