Case Study: Nomura Securities International Inc. achieves 35% reduction in physical servers and global IT cost transparency with Apptio

How Nomura’s Global Cost Model Shapes Business Demand

Nomura, an Asia-based global financial services firm, faced a rapidly growing IT cost base after acquisitions and an infrastructure build-out. Traditional ledger project codes and inconsistent regional accounting hid true consumption and left business units treating technology costs as an uncontrollable “tax,” so Nomura needed actionable, business-facing cost transparency to manage demand and spending.

Nomura implemented a TBM-based global cost model—regional automated models mapped to a common taxonomy and services defined in business terms with consumption-driven allocation. The approach enabled clearer chargebacks, faster build-vs-buy and what-if analyses, rolling forecasts and joint investment planning, and drove concrete savings including a 35% reduction in physical servers within a year.
