Purpose
Translate vague "we need better data quality visibility" requests into a precise, buildable requirements document — with defined metrics, calculation logic, per-segment acceptance criteria, and alert thresholds — so a BI or reporting partner can build the dashboard without a dozen clarifying calls.
When to Use
Invoke this skill when the user asks to:
- Scope or spec a data quality dashboard for a BI/reporting team
- Define data quality metrics (fill-rate, accuracy, freshness, cost-per-record, pipeline reliability)
- Set acceptance criteria or SLAs for data quality by segment
- Write requirements to hand off to an analytics engineer or BI partner
- Establish thresholds and alerting for a data pipeline or CRM data health
- Standardize how data quality is measured across records, accounts, or segments
Inputs Required
Before starting, collect:
- Data domain: What data is being measured (e.g., CRM accounts, lead records, product usage events, enrichment data)
- Primary systems/sources: Where the data lives (Salesforce, HubSpot, warehouse tables, enrichment vendor feeds)
- Segments to track separately: How data should be sliced (e.g., by region, tier, source, record type, owner team)
- Key fields that matter most: The 5–15 fields where quality has business impact (e.g., email, industry, employee count, MRR)
- Consumers of the data: Who relies on it downstream (SDRs, forecasting, routing, marketing ops)
- Existing SLAs or pain points: Known problems or targets already agreed upon
- BI/reporting stack: The tool the dashboard will be built in (Tableau, Looker, Power BI, Sigma, etc.)
If segments or key fields are missing, propose a sensible default set and flag it as an assumption for the buyer to confirm.
Instructions
Step 1: Confirm Scope and Segmentation Grain
Establish the unit of analysis before defining any metric.
- Grain: Is quality measured per record, per account, per event, or per field?
- Segmentation dimensions: List the 2–4 dimensions each metric will be sliced by (region, tier, source, owner).
- Reporting frequency: Real-time, daily snapshot, or weekly rollup — this drives freshness expectations.
- State the grain explicitly at the top of the output; every metric below inherits it.
Step 2: Define the Five Core Metric Families
For each of the five families, produce a metric definition block with: Metric name, What it measures, Calculation formula (in plain SQL-like pseudocode), Data source(s), Segmentation applied, and Refresh cadence.
Family 1 — Fill-Rate (Completeness)
- Percentage of records where a required field is populated with a non-null, non-placeholder value.
- Formula pattern:
COUNT(records WHERE field IS NOT NULL AND field NOT IN ('', 'N/A', 'unknown')) / COUNT(records) per segment - Define completeness per key field AND a weighted composite fill-rate across the field set.
Family 2 — Accuracy (Validity/Conformance)
- Percentage of populated values that conform to expected format, range, or reference list.
- Formula pattern:
COUNT(records WHERE field MATCHES validation_rule) / COUNT(records WHERE field IS NOT NULL) - Specify the validation rule per field (email regex, employee-count range, industry in picklist, domain resolves).
Family 3 — Freshness (Timeliness)
- Age of the most recent update relative to expected refresh cadence.
- Formula pattern:
NOW() - MAX(last_modified) per record/segment; report % of records updated within SLA window. - Distinguish source freshness (when the pipeline last ran) from record freshness (when a record last changed).
Family 4 — Cost-per-Record (Efficiency)
- Total data acquisition/enrichment/maintenance cost divided by records processed or held.
- Formula pattern:
SUM(enrichment_spend + tooling_cost) / COUNT(records) per source/segment - Include a cost-per-usable-record variant (cost / records passing accuracy + fill thresholds).
Family 5 — Pipeline Reliability (Operational Health)
- Success rate and stability of the jobs feeding the data.
- Metrics: job success rate (
successful_runs / total_runs), duplicate rate, row-count variance vs. prior run (%), and SLA-miss count. - Flag anomalies where row counts deviate more than a defined % from the trailing average.
Step 3: Set Acceptance Criteria Per Segment
Build a segment × metric matrix. For each metric family, define three thresholds per segment:
- Target (green): the desired state
- Acceptable (yellow): tolerable but monitored
- Breach (red): triggers action
- Higher-value segments (top tier, primary regions) warrant stricter thresholds than long-tail segments — make this explicit rather than applying one flat standard.
Step 4: Define Alerting and Ownership
For each red-threshold breach, specify:
- Trigger condition (metric + threshold + segment)
- Alert channel (Slack, email, dashboard flag)
- Owner (which role investigates)
- Escalation window (how long before it escalates)
Step 5: Specify Dashboard Layout for the BI Partner
Describe the intended views so the reporting team can build directly:
- Executive summary tile: composite health score per segment, RAG-coded
- Metric drill-downs: one view per metric family with segment filters
- Trend view: each metric over time (rolling 90 days minimum)
- Breach log: table of current and recent threshold violations
- List required filters, default date range, and any calculated fields the BI tool must create.
Output Format
- Structure: A requirements document organized in five parts — Scope & Grain, Metric Definitions, Acceptance Criteria Matrix, Alerting & Ownership, Dashboard Layout Spec
- Length: 1,000–1,500 words
- Format: Structured document with metric definition blocks, one acceptance-criteria table (segment × metric with three thresholds each), and a bulleted layout spec
- Sections: Scope & Segmentation Grain → Core Metrics (5 families with full definition blocks) → Acceptance Criteria Matrix → Alerting & Ownership → Dashboard Layout Spec → Open Questions for the BI Partner
- Tone: Data ops manager writing a handoff spec — precise, unambiguous, formula-first; no marketing language
Quality Checklist
Before delivering output, verify:
- [ ] All five metric families are defined (fill-rate, accuracy, freshness, cost-per-record, pipeline reliability)
- [ ] Every metric includes a calculation formula in SQL-like pseudocode — not just a description
- [ ] The acceptance criteria matrix includes three thresholds (target/acceptable/breach) for every segment
- [ ] Segmentation grain is stated once and applied consistently across all metrics
- [ ] Every red-threshold breach has an assigned owner and alert channel
- [ ] Dashboard layout spec names specific views, filters, and calculated fields the BI tool must create
Notes
- Accuracy is the metric most often skipped because it requires validation rules — push the buyer to define at least a format or reference-list rule per key field, since fill-rate without accuracy overstates health.
- Freshness commonly conflates pipeline-run time with record-change time; keep them as separate metrics or the dashboard will hide stale-but-recently-touched records.
- One flat threshold across all segments is the most common spec mistake — tiered acceptance criteria are what make the dashboard actionable for a RevOps team.
- If the BI tool can't compute a metric server-side (e.g., cost-per-record spanning finance and CRM data), note it as an "Open Question for the BI Partner" rather than assuming it's buildable.
