KPI, Metric and Semantic-Layer Dictionary
Enterprise single source of truth KPI and semantic layer dictionary workbook detailing canonical business metrics, mathematical formulas, dimensional grain, aggregation rules, and certified governance owners.
Financial and operational metric dictionary defining authoritative calculations (ARR, NRR, CAC, LTV, Gross Margin, DAU/MAU) and semantic layer code configurations across enterprise data warehouses.

Problem Solved
Finance, Marketing, and Engineering teams calculate core metrics (like ARR, active users, or churn) using conflicting custom SQL formulas, producing contradictory figures in board meetings and eroding executive trust.
When to Use
- •Establishing a definitive, board-approved single source of truth for corporate performance metrics
- •Configuring modern semantic layers (dbt Semantic Layer, Cube.js, Looker LookML)
- •Preparing financial statements, investor reporting, and IPO/M&A due-diligence data rooms
When NOT to Use
- •For short-term experimental metrics evaluated only during a temporary 2-week marketing campaign
- •For low-level microservice CPU memory telemetry (use TPL-OPS-001)
5 Template Sections & Structural Outline
Categorizing strategic (C-level), tactical (departmental), and operational metrics with designated executive owners.
Exact algebraic formulas, handling of refunds, discounts, multi-currency conversions, and leap years.
Valid dimensions (Geography, Cohort, Plan Tier, Channel) and non-additive metric rules (e.g. ratios, percentages).
Deployable dbt MetricFlow / Cube.js schema specifications referencing underlying dimensional warehouse tables.
Annual metric formula review, change-control approval boards, and historical restatement protocols.

Frequently Asked Questions
Why is a centralized semantic layer superior to BI-tool-specific metrics?
When metrics are defined inside BI tools (like Tableau or Power BI), definitions diverge when users build models in another tool. A centralized semantic layer (dbt MetricFlow, Cube.js) defines metrics once in the data warehouse, serving identical calculations via SQL/APIs to any connected tool.
What is a non-additive metric and why does it require special handling?
Non-additive metrics (e.g. ratios like Gross Margin % or point-in-time balances like Inventory Levels) cannot be summed across dimensions (e.g. summing US Gross Margin 70% and EU Gross Margin 60% does not equal 130%). The semantic layer re-computes the ratio from underlying sums.
What protocol should govern historical restatements when a metric formula changes?
When a canonical metric formula is revised, the governance board determines whether historical data must be back-calculated. Major revisions require versioning (e.g. `ARR_v2`) and dual-reporting for at least two fiscal quarters to prevent unexpected financial variance.
