Case Study: NGK Spark Plugs achieves a zero‑downtime SAP EHP6 upgrade in 2½ months with Panaya

NGK Spark Plugs Upgraded To EHP6 With Zero Downtime

NGK Spark Plugs, the world leader in spark plugs with a presence in 17 countries and 14 factories across 8 nations, faced a critical SAP upgrade from EHP4 to EHP6. Having never performed an EHP upgrade and operating as an OEM just‑in‑time supplier, NGK could not tolerate any downtime and needed the upgrade to remain compatible with satellite systems.

NGK used Panaya’s Change Analytics to scope the project and Panaya Testing Accelerators for UAT and business analysis testing, enabling rapid, focused remediation. The upgrade was completed in 2½ months with zero downtime, early detection of errors, a smooth go‑live that exceeded expectations, and renewed confidence in their testing process.
