Data quality management validates and monitors data as it moves through your pipelines, catching bad records before they reach a report. That matters because these failures stay invisible until something important breaks. A pipeline that silently drops records when a source field is null delivers a report that looks complete: the row count is close enough, the numbers are plausible, and nobody questions them until a decision made on that data produces a bad outcome. By then the root cause is buried in pipeline logs from three weeks ago, and finding it takes days.
The fix is data quality infrastructure that validates data as it moves through the pipeline, not after the fact, and not only when someone notices a number looks wrong. Schema validation before the load, row count checks after the load, statistical anomaly detection on the delivered data, and freshness SLAs that alert before a stale table reaches a report. We build that infrastructure as a defined engagement scoped to your existing pipeline and warehouse setup.
Poor data quality costs organizations an average of $12.9 million per year (Gartner). For most data teams, that figure compounds quietly: wrong decisions made on silent pipeline failures whose root cause never gets traced, and whose downstream impact never gets measured.
Capabilities
What we build
dbt schema tests written as SQL assertions that run at the end of every pipeline execution, before transformed data reaches analysts or dashboards. Built-in and custom tests catch nulls, duplicate keys, invalid values, broken foreign keys, and domain rules like non-negative revenue, with results stored in the warehouse so quality trends per table stay queryable rather than buried in CI logs.
- Built with
- dbt tests · SQL assertions
02Row count and freshness monitoring
Expected row count ranges established per table from historical delivery data, with alerts at configurable thresholds. This catches the partial-load failure mode, where a source timeout leaves the pipeline "successful" with a fraction of the records and the warehouse looks current but is materially incomplete. Freshness SLAs alert the moment a table goes stale.
- Built with
- dbt source freshness · Slack · PagerDuty
03Statistical anomaly detection
Statistical anomaly detection applied to the values inside delivered data, not just row counts. Baselines built from history with seasonal decomposition flag deviations in metrics like daily revenue and transaction success rate. This catches semantic failures that pass every structural test, and the alert fires before the CFO sees a phantom revenue drop.

- Monte Carlo · Great Expectations · Custom SQL · Slack or PagerDuty
04Schema change detection
Schema change detection runs as a pre-load validation step: the current source schema is compared against a registry, and any discrepancy alerts before data loads with an unexpected structure. New, removed, renamed, and type-changed columns are each handled by per-table evolution policies, and a queryable change log answers "why did this model break six weeks ago?" in under two minutes.
- Built with
- Schema registry · dbt models
Column-level lineage tracked from the raw source table through every transformation to the final mart and the BI measures that read from it. The graph enables forward impact analysis, the blast radius of a source schema change, and backward root cause analysis, tracing a wrong dashboard number to exactly where the value diverged.
- Built with
- DataHub · Atlan · Collibra · dbt docs
06Data quality dashboards and reporting
Centralized data quality dashboard built in the BI tool your team already uses, pulling test results, anomaly history, freshness compliance, and schema changes into one queryable dataset. Every monitored table carries a named data owner, so alerts route to the right person, and a weekly summary replaces the ad-hoc "is the data trustworthy?" conversation with evidence.
