Case Study: ESB achieves a smooth SAP S/4HANA migration with Expleo Continuous Quality

Safeguarding ESB’s journey to S/4HANA

The Irish energy company ESB faced significant challenges in its brownfield implementation of SAP S/4HANA across its finance, supply chain, and HR units. The scale of the migration, coupled with a lack of upfront requirements and documentation, made ensuring quality and reliability paramount. To safeguard this transformation, ESB partnered with Expleo to implement a comprehensive Continuous Quality strategy.

Expleo provided a complete Continuous Quality solution, executing all phases of testing including system integration, user acceptance, and performance testing. They leveraged an onshore and offshore resourcing model to create test cases and manage defect triage, which improved testing efficiency. Expleo delivered an automated regression pack that ensured a smooth go-live and provided a foundation for supporting all future enhancements to the S/4HANA platform.
