What is FOCUS™?

The FinOps Cost and Usage Specification (FOCUS™) is an open-source specification that defines clear requirements for cloud vendors to produce consistent cost and usage datasets.

Supported by the FinOps Foundation, FOCUS™ aims to reduce complexity for FinOps Practitioners so they can drive data-driven decision-making and maximize the business value of cloud, while making their skills more transferable across clouds, tools, and organizations.
