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 is scoped by need: a focused dashboard project or an enterprise-wide analytics platform with governance frameworks. 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 transformed the economics of enterprise Power BI in 2026. Semantic models can now query Parquet files stored in OneLake. This offers performance comparable to Import mode, but without the cost of refresh windows.

A Fortune 500 finance organization is moving away from a 30-minute Import-mode refresh. The Direct Lake model typically queries fact data in under 800 ms. This change also eliminates the need for the entire refresh-orchestration job in Azure Data Factory.

Row-level security (RLS) and object-level security (OLS) in Power BI Premium and Fabric F-SKU capacities are essential compliance controls. These features are often overlooked, but they are crucial for:

  • Protecting sensitive data
  • Ensuring proper access rights
  • Maintaining regulatory compliance
  • HIPAA
  • SOC 2
  • FINRA-regulated environments

RLS scoped through service principal authentication is the only method that passes a SOC 2 Type II auditor privilege-walk test. This approach is preferred over embedded UPN passes.

EPC Group includes service-principal RLS as a standard in every Power BI engagement for regulated industries.

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)

Power BI best practices — the EPC Group field reference

This Power BI best-practices reference is based on EPC Group's Microsoft consulting experience since 1997. It draws from the expertise of senior architects who have implemented enterprise Power BI environments.

These professionals have worked with Fortune 500 clients in regulated industries, ensuring successful outcomes.

The patterns and trade-offs discussed here are derived from real production work, not vendor presentations.

Senior-architect-led delivery

Every Power BI engagement is led and staffed by 15 to 20 year veterans. No rotating juniors learning on your tenant.

The bench includes hundreds of Microsoft-certified consultants. They have delivered real production Power BI environments at scale. Their expertise covers:

  • Semantic-model governance
  • Premium capacity sizing
  • Row-level security for HIPAA and SOC 2
  • Microsoft Fabric integration

Compliance-native, not bolted on

We have achieved no reported governance audit failures across HIPAA, SOC 2, FedRAMP, and CMMC engagements across over 11,000 enterprise engagements. Our controls include:

  • HIPAA
  • SOC 2
  • FINRA
  • FedRAMP
  • CMMC

These controls are built into the tenant from day one, ensuring audit-ready evidence is always available.

EPC Group is a Microsoft Solutions Partner. We have important designations in Modern Work, Security, and Data & AI.

From 2000 to 2022, EPC Group was the longest-serving Microsoft Gold Partner in North America before the program ended.

How EPC Group ships Power BI

Six-phase methodology applied to every engagement:

  1. Discovery — assess existing Power BI estate, semantic models, capacity utilization, governance gaps, and compliance obligations.
  2. Design — target semantic-model architecture, workspace topology, RLS framework, capacity sizing, and governance operating model.
  3. Pilot — deploy one business unit's reporting onto the new architecture. Validate performance, security, and adoption.
  4. Wave rollout — migrate remaining workspaces in waves with hypercare and per-wave retrospective.
  5. Adoption — role-based training (executive, analyst, business user), Champions network, dashboard governance reviews.
  6. Operate — optional managed-services retainer for capacity tuning, license optimization, and quarterly business reviews.

Engagement models

  • Fixed-fee accelerators — Power BI Tenant Health Check, Semantic Model Audit, Capacity Sizing, Migration to Fabric. Fixed price stated in the proposal; four to twelve weeks.
  • Project engagements — full Power BI program with milestone-based billing. Scoped after discovery; three to nine months.
  • Managed services — tiered retainer for ongoing operations. From $3,500 per month with a twelve-month minimum.
