Samsung: A Governed Power BI Ecosystem

The business challenge

Samsung's reporting environment mixed legacy reporting technologies, enterprise systems, on-premises data sources, cloud environments and independently developed reports — SAP BusinessObjects, Tableau, SAP data, ISPASS, Google Cloud/Big Data and other operational sources. Information was available but not easy to maintain, integrate, govern or consume consistently. Migration was never just recreating charts: understanding where data came from, how reports calculated their metrics and which reports were still relevant were the real challenges.

The solution

Z&C worked from report migration up to data architecture. Legacy reports were reviewed first — KPIs, source systems, SAP dependencies, existing Tableau and BusinessObjects logic, refresh requirements, consumers, security and consolidation opportunities — then rebuilt across source, integration, and analytics & presentation layers. Every migrated report went through logic validation and reconciliation so it could never silently produce a different business result.

Implementation

• Source layer

  SAP, ISPASS, Google Cloud/Big Data, enterprise databases, legacy reporting sources and operational systems brought into one governed architecture.

• Integration layer

  Alteryx, APIs, iPaaS, ETL/ELT processes, data transformations, gateway connectivity and RPA where appropriate.

• Analytics & presentation layer

  Power BI semantic models, DAX, Power Query, reusable KPIs and row-level security powering reports, apps and executive/operational dashboards.

• On-premises bridge

  The Power BI gateway bridged on-premises sources so enterprise data kept supporting reporting during the transition.

• Logic validation & reconciliation

  SQL logic, joins, filters, aggregations, date logic and DAX validated per migrated report; report-specific calculations moved toward reusable governed business logic.

Business results

• Governed foundation

  Multiple enterprise sources now feed one Power BI ecosystem with centralized, reusable business logic.

• Consistent KPIs

  Executive and operational reporting share the same definitions across finance, procurement, operations and customer care.

• Security & control

  Governed access and distribution through Power BI Apps, with cloud and on-premises data coexisting.

• Future-ready platform

  A foundation positioned for new analytics and AI use cases — not just a visualization tool.
