SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps you diagnose whether your metrics system can be trusted to support decisions by checking definition consistency, data quality, coverage gaps, experimentation rigor, self-service readiness, and governance.

Core Features & Use Cases

  • Core metric consistency checks: Detect mismatched definitions, unclear calculations, and non-single-source-of-truth metric logic.
  • Data reliability diagnostics: Identify collection gaps, duplicates, delays, and pipeline stability risks.
  • Decision coverage and experimentation review: Find missing analytical signals and evaluate A/B test infrastructure and statistical reporting practices.
  • Self-service vs analyst dependency and governance: Assess whether teams can retrieve answers quickly and whether access/PII/retention controls are in place.

Quick Start

Run the data diagnosis skill to produce a metrics and data-infrastructure diagnostic report for your project.

FAQPage Schema
How do I audit business metrics for definition consistency and single source of truth conflicts?

To audit business metrics for definition consistency, cross-reference tracking and analytics code with metric definitions and dashboards to detect mismatched calculations and resolve single source of truth conflicts. This process produces prioritized findings for reliable decision-making.

What is experimentation readiness assessment and how does it evaluate A/B test infrastructure?

Experimentation readiness assessment evaluates A/B test infrastructure and statistical reporting practices to find missing analytical signals. It diagnoses whether your metrics system can be trusted to support decisions by checking data collection, tracking coverage gaps, and governance.

How can I identify tracking coverage gaps and data pipeline reliability risks?

Identify tracking coverage gaps and data pipeline reliability risks by running diagnostics that detect collection gaps, duplicates, and delays. This data reliability diagnostic cross-references analytics code against metric definitions to highlight stability risks.

Can I assess data governance and self-service readiness without analyst dependency?

You can assess data governance and self-service readiness by checking whether teams can retrieve answers quickly and verifying access, PII, and retention controls. This diagnostic evaluates if your metric definitions and dashboards support independent querying.

What is the best way to diagnose dashboard metrics for decision trustworthiness?

The best way to diagnose dashboard metrics for decision trustworthiness is to perform a comprehensive metrics and data-infrastructure audit. This detects non-single-source-of-truth metric logic and data quality issues, producing a diagnostic report without drifting into outcome optimization.
