COST03-BP03: Establish organization metrics

Define and implement metrics that provide meaningful insights into your organization's cloud cost performance. Well-designed metrics enable data-driven decision-making, support accountability, and help track progress toward cost optimization goals.

Implementation guidance

Organization metrics provide the quantitative foundation for cost management and optimization decisions. These metrics should align with business objectives, be easily understood by stakeholders, and enable actionable insights that drive cost optimization activities.

Metric Design Principles

Business Relevance: Metrics should directly relate to business outcomes and objectives, enabling stakeholders to understand the business impact of cost decisions.

Actionability: Each metric should enable specific actions or decisions that can improve cost performance or business outcomes.

Measurability: Metrics must be quantifiable and consistently measurable over time to enable trend analysis and performance tracking.

Comparability: Design metrics that enable meaningful comparisons across time periods, business units, projects, or industry benchmarks.

Metric Categories

Financial Metrics: Direct cost measurements including total spend, cost trends, budget performance, and unit economics.

Efficiency Metrics: Measurements of resource utilization, waste, and cost-effectiveness that indicate optimization opportunities.

Business Metrics: Metrics that relate cloud costs to business value, such as cost per customer, cost per transaction, or revenue efficiency.

Operational Metrics: Measurements of cost management processes, governance effectiveness, and optimization program performance.
