Total Cost of Ownership

The data existed. The experience to make sense of it didn't. Tech Finance needed visibility into total cost of ownership — organized around how finance leaders actually think about spend, not how the data is stored.

3.67M
Monthly cost records made accessible without manual aggregation

Dashboards, each organized around a distinct planning need — not a data category
35
Financial planning users who no longer compile reports manually each cycle

Walmart Global Tech had 3.67 million monthly cost records across multiple systems and no coherent view of what any of it meant. Investment decisions were being made without reliable cost transparency — technology spend was happening faster than the reporting could follow it. The core research finding: finance leaders think about spend by product area and initiative, not by the data categories the systems used to store it. That gap was the whole problem.

Research also surfaced that trend visibility was the highest-value need (not point-in-time data), and that manual compilation was consuming significant time every reporting cycle for no analytical gain. Five dashboards addressed all three: organized around product area and initiative, with trend as a first-class view, and data surfaced automatically rather than assembled by hand.

Org View — spend by category across the fiscal year, drillable from portfolio level to individual product areas.

Five dashboards shipped at soft launch to 35 financial planning users. Decision-makers got the cost visibility to make informed investment decisions without manually assembling reports at the start of each reporting cycle.

What changed

Research identified the organizing principle: finance leaders think about spend by product area and initiative, not by data category. That single insight drove the entire IA — five dashboards built around decision-making patterns rather than system architecture. Manual report compilation for 35 planning users at the start of each cycle became unnecessary.
