The difference is whether it can distinguish a meaningful business defect from harmless change—and help the right people act on it. Raj Joseph, President & CEO of DQLabs, frames that challenge through six factors: scale, context, organizational maturity, business impact, time and cost to value, and stewardship. Those are Joseph’s criteria, not a standardized scoring model.
What “noise” looks like in data quality
Noise is activity that does not improve understanding or trust: bespoke checks that do not keep pace with changing data, alerts that mistake an intentional change for a defect, or findings with no clear owner. In DQLabs’ article “The Noise in Modern Data Quality,” last updated April 23, 2026, Joseph argues that a useful approach must fit both the data environment and the purpose people have for the data.

His questions are practical: “what data is good for what purpose?”, “what data can be used where?”, “how can we improve?”, and “What data is sensitive?” They address fitness for use, appropriate application, improvement and sensitivity—not simply whether a table passed a technical check.
Six factors that separate useful quality work from noise
Scale without a bespoke-check burden
Data grows in volume, variety and architectural complexity. A quality program needs to accommodate that expansion without turning every new dataset or pipeline into a one-off engineering project. Otherwise, coverage lags behind the environment it is meant to govern.
#1 Best Overall
Context and fitness for purpose
A value cannot always be judged in isolation. Joseph uses annual income as an example: marketing, risk analysis and underwriting may interpret or use the same field differently. A check that ignores the intended use can flag acceptable data or approve data that is unsuitable for a particular decision. As Joseph puts it, “If we don’t understand the data from a context, it’s pretty much useless putting any solution.”
Maturity and organizational change
Organizations evolve, sometimes by acquiring systems and processes through mergers and acquisitions. A workable approach should adapt to that changing landscape rather than assume a fixed set of sources and processes—or force a platform change every year.
Business impact, not just statistical surprise
An outlier is not automatically a problem. A price reduction deliberately introduced to improve customer retention may look unusual in a distribution while being consistent with strategy. Quality decisions need to account for purpose and consequences: is the value wrong, or is the change intentional and meaningful?
Time and cost to value
Implementation effort matters because data landscapes, regulatory needs and customer expectations change. The relevant question is whether the work required to establish and operate a quality practice is proportionate to the value it can deliver—not merely whether a tool can run a check.
Rank #3
Shared stewardship
Technical users can investigate pipelines and implement controls; business users can explain definitions, intended use and impact. Both need a role in building shared understanding. Without that connection, technically valid findings may remain unresolved or business decisions may rely on assumptions that were never encoded.
Observability finds change; quality checks judge correctness
Data observability monitors the health and behavior of data assets and pipelines. Common signals include freshness, row-volume anomalies, distribution changes, schema drift, pipeline failures and lineage. These signals can show that something changed or failed, but they do not establish by themselves that the business values are correct.
Data quality defines what “good” means for a particular purpose and validates data against that definition. Ataccama’s March 19, 2026 article describes dimensions including validity, completeness, uniqueness, accuracy and timeliness, and distinguishes data that arrives on time from data that is correct for its intended use. Its concise formulation is: “Pipeline health is not the same thing as business correctness.”
A useful operating model combines broad monitoring with deeper, business-specific validation: observability helps locate when and where behavior changed; definitions and rules help determine whether the change is a defect. This distinction matters when an intentional business action—such as a strategic price reduction—resembles an anomaly.

Make alerts lead to a decision and an action
Ataccama describes a practical loop as detect → triage → remediate. For an alert to be useful, the people handling it need enough information to judge its significance and take responsibility.
- Detect: Identify what changed and how far it deviated, using monitoring signals or a business-specific rule.
- Triage: Establish the affected data, downstream assets, owner and relevant business definition. Lineage can help trace an issue upstream to its origin and downstream to its impact; incident history can show whether a similar event occurred before.
- Remediate: Address the cause, not only the alert. Depending on the finding, that may mean correcting a recurring pattern, tightening an appropriate governed rule, or moving a check upstream where prevention is possible.
These are operating practices described in Ataccama’s article, not guaranteed performance outcomes. Anomaly detection can surface unexpected patterns, but “unusual” is not synonymous with “harmful.” Suppression, grouping, context and ownership are useful only when they reduce irrelevant alerts without concealing real incidents. Anomalo’s product page describes capabilities including unsupervised machine-learning checks, false-positive suppression, alert routing, root-cause analysis and lineage; those are vendor claims, not independent comparative measurements.
Joseph captures the cost of alerts without context: “The last thing anyone wants to do is get spammed — doesn’t matter if it’s email or slack or spending hours on root cause analysis to figure out it’s OK!”

Compare operating models and tools against the work your organization needs them to do. These are evaluation axes, not a product ranking or evidence that any vendor has been tested against another.
- Coverage: Does the approach combine business-specific validation with monitoring for freshness, schema, volume and distribution changes?
- Meaning: Can it represent organizational definitions, usage context, sensitivity and criticality?
- Impact: Can users trace lineage and understand which downstream assets may be affected?
- Actionability: Do alerts explain what changed, provide enough context to investigate, route to an accountable owner and help avoid repeated root-cause work?
- People: Can business stewards and technical users both participate in defining, investigating and improving quality?
- Fit and adaptability: Does the approach suit the organization’s scale, architecture and integrations, and accommodate organizational change?
- Practical value: Is the implementation effort proportionate to expected value and the organization’s changing operational and regulatory needs?
No single monitoring signal can answer every question. A freshness check may show that data arrived; a business rule may determine whether the values are fit for a particular decision. Trust depends on connecting those signals to context, ownership and a useful response.
