Worked on enhancing documentation for the FinOps-Open-Cost-and-Usage-Spec/FOCUS_Spec repository, focusing on clarifying the definition of Usage Quantity and providing detailed example scenarios for allocated records. Applied data modeling and technical writing skills to improve the accuracy and clarity of cost attribution, ensuring the documentation aligns with FinOps standards and repository guidelines. Utilized Markdown to structure and present information effectively, addressing a copy and paste issue and refining split-cost examples to reduce onboarding friction. The updates aimed to make usage quantity definitions more actionable, supporting maintainability and reducing support queries for users integrating with the cost and usage specification.
