Industry Leaders We Work With

“70% of gen AI high performers report difficulties with data, including governance processes.” — McKinsey & Company

Even companies getting the most from AI struggle with their data. Zoolatech starts there: a written standard, a named owner, and a score.
Definition and Scope

What Data Quality Management Is

Data quality management defines good enough for each dataset, then measures against it continuously.
Defined per dataset

Defined per dataset

Good enough is set for each dataset from the decision it feeds, not from a generic benchmark or tool default.
Measured continuously

Measured continuously

Checks run on a schedule against that definition, so quality is observed every day instead of audited once a year.
Written down

Written down

The standard sits where producers and consumers both read it, which ends the argument about what correct means.
Assigned to an owner

Assigned to an owner

Each standard belongs to a named person who answers for it, because a number without an owner changes nothing.
Reported against

Reported against

Results are reported against the standard, so quality becomes a state you can observe, not a claim you repeat.
Fixed at the cause

Fixed at the cause

When data falls short, the work targets what produced the defect, such as a form, a definition, or an integration.
Cleansing is an action

Cleansing is an action

A cleansing project has an end date. Data quality management services are judged on what holds after it.
Management is a state

Management is a state

Quality that was fixed once and never measured again is indistinguishable from quality that was never fixed.
Quality Dimensions

Six Dimensions We Measure

A dataset can be accurate and still three days late.
Accuracy

Does the value match reality?

  • Fields compared against a system of record or verified sample
  • Manual sampling used where no reference exists
  • Results reported per field, so remediation has an address
  • Threshold set by the decision the field feeds
  • Example: 99% of sampled addresses match the postal reference
Completeness

Do required fields carry values?

  • Share of required fields that actually carry a value
  • Optional source fields separated from fields the decision needs
  • Threshold applies to the second group only
  • Data quality and enrichment services fill what was never captured
  • Example: 97% of orders carry a valid tax code
Consistency

Same entity in every system?

  • Record counts and key attributes reconciled across systems
  • Mismatch rate reported per customer, order, and product
  • Most mismatches trace to two definitions, not broken integrations
  • Master data and entity ownership sit with data governance
  • Example: customer counts differ by under 0.5% between systems
Timeliness

Fresh enough for the decision?

  • Freshness is a business requirement, not a technical one
  • Data age measured against what each decision needs
  • Zalando events: 15–90 minutes late, now near real time
  • Threshold stated in minutes or hours per dataset
  • Example: checkout events available within 15 minutes
Validity

Right format, range, and reference?

  • Type, pattern, referential integrity, and business range rules
  • Every check runs as an explicit, named rule
  • A failure names the rule it broke
  • No generic alerts that someone has to decode
  • Example: zero prices outside the approved range per category
Uniqueness

One record per real entity?

  • Duplicate rate measured before any merge happens
  • Entity resolution links records that describe one entity
  • Duplicates traced to the input path that creates them
  • Data quality and cleansing services fix what is already wrong
  • Example: duplicate customer rate below 1% after matching

Maturity Assessment

Where Your Data Stands Today

Data quality consulting services start by placing your organization on this scale.
Reactive
Measured
Committed
Contracted

Found by accident

The business finds the problem first, when a report disagrees with what somebody knows.
  • How it looks: Nothing is measured, and fixes happen one complaint at a time.
  • What breaks: Trust, before anything technical does.
  • First move: Data quality assessment services profile the datasets behind the reports people already argue about.
Image slot 400

Numbers without consequences

Quality is measured and visible, but no number is binding on anyone.
  • How it looks: Dashboards show scores per table, with no target beside them.
  • What breaks: The dashboard gets watched for a quarter, then ignored, because nothing follows from a red cell.
  • First move: Turn those measurements into thresholds with named owners.
Image slot 400

Thresholds with owners

Thresholds are set, each critical dataset has an owner, and breaches get investigated.
  • How it looks: A scorecard reports each dataset against its thresholds on a fixed cadence.
  • What breaks: Upstream schema changes still arrive unannounced.
  • First move: Instrument monitoring and write down what happens when a threshold is missed.
Image slot 400

Agreed in writing

A contract binds producers and consumers on schema, update frequency, and change notice.
  • How it looks: Schema changes get negotiated before release, not discovered after.
  • What breaks: Less, and more slowly.
  • First move: Extend contracts and thresholds to the next tier of datasets.

Data Types

Which Data We Work With

The mechanics of quality differ by data type, so the checks do too.

Customer records

Customer records decay fastest. CRM data quality services track duplicate rate, contactability, and consent validity on a schedule.

Transactions and products

Price, tax, and inventory fields pass their own checks yet disagree across the systems that publish them.

Analytical marts

Marts inherit every upstream defect and add their own in transformation logic. Analytics data quality services start at metric definitions.

Training data

Free text and training sets need coverage, representativeness, and label checks that classic data quality enhancement services never included.
AI and Quality

AI and Data Quality, Both Directions

AI data quality services cover two projects: models checking data, and data fit for models.
check icon

Anomaly detection on streams

Rules catch values outside a range. Models catch the record that is individually valid and collectively wrong, such as an order volume plausible for a Tuesday but not for this Tuesday.
check icon

Validation of free text

No pattern validates an address, a product description, or a support note. LLM-based checks classify free-text fields against your taxonomy, flag what does not belong, and route uncertain cases to a person.
check icon

Model-assisted entity resolution

Exact and fuzzy matching miss duplicates that differ in every field yet describe one entity. Embedding-based matching finds them, and a confidence threshold decides what merges automatically and what a steward reviews.
check icon

Classification of incoming records

Incoming text gets a category before it reaches reporting. In our Gen AI text analysis pipeline, Gemini on Vertex AI classifies records inside BigQuery and Dataform, so analysts query labeled data instead of raw comments.
check icon

Noise filtering at entry

The cheapest quality fix is refusing bad input. On a media analysis platform built on Amazon Bedrock with Anthropic Claude and Amazon Titan, models filter incoming content so only high-signal material reaches the insight layer.
check icon

Coverage and representativeness

A report needs its numbers right. A model needs its data representative. A dataset can pass every accuracy check and still miss the segment where the model fails, so coverage becomes a scored dimension.
check icon

Bias in training data

Fairness is measurable before deployment. Our machine learning practice runs systematic fairness testing across protected attributes to identify and mitigate bias in training data and model outputs before deployment approval.
check icon

Label quality

A model is bounded by its labels. Annotator agreement, class balance, and drift in the labeling guidelines are all measurable, and they belong on the same scorecard as accuracy.
check icon

Distribution drift

Training data and production data diverge. Monitoring the distance between them turns silent model degradation into a threshold breach with an owner, the same mechanism as any other data SLO.

“63% of organizations lack or doubt their data management practices for AI.” — Gartner

A model trained on unscored data inherits every defect in it. Zoolatech scores coverage, bias, labels, and drift before training starts.
Root Cause Analysis

Fixing the Cause, Not the Symptom

Cleaning a dataset without changing what fills it buys about a quarter. These patterns explain most recurring defects.
01

Forms create duplicates

Duplicates come from an input path that writes without a match check. Deduplication alone becomes a recurring cost line.
02

Two definitions collide

A mismatch between systems usually means two definitions. We settle which “active customer” the business meant before touching any integration.
03

Optional at capture

Missing values usually mean the field was optional where it was captured. The fix lives upstream, not in a backfill.
04

Untraceable failures

On a construction-tech platform, lifecycle logging and tagged metrics cut root cause investigation from hours or days to minutes.
Most data quality programs end at a dashboard showing how bad things are. This one ends at a stated threshold on your critical datasets, an owner accountable for it, and a report on whether it was met.

Data SLOs and Contracts

Turning Measurement into Commitment

Most data quality methodologies stop at measurement: they tell you how bad the data is without stating how good it has to be, who is responsible for that number, or what happens when it is missed.
Step 1

A data SLO states a threshold for freshness, completeness, and accuracy on a named dataset, with an owner accountable when it is missed. Data SLOs shipped in Zalando’s stack beside Spark, Braze, and Looker.
Step 2

A data contract binds the team producing a dataset and the teams consuming it on schema, update frequency, and change notice. Schema changes get negotiated weeks ahead instead of breaking four dashboards on a Monday.
Step 3

For each dataset we write down what we check, at which stage, and what severity a failure carries. Data quality testing services and data quality assurance services mean exactly this.
Step 4

A scorecard reports each dataset against all six dimensions separately, for example completeness at 94% against a 97% threshold, with an owner on every row. One blended score hides which dimension is failing.
Cost of Defects

What Bad Data Costs

Bad data rarely appears as a line in a budget, which is why it survives.
Lost revenue

Lost revenue

Improving customer data quality and pipeline reliability at Zalando enabled a potential €4.5M GMV uplift through more precise marketing activation.
Rework

Rework

Analysts reconcile instead of analyzing, a share of a senior team’s week that nobody logs as a defect.
Delayed decisions

Delayed decisions

A report nobody trusts does not get used. The decision still gets made, later and by instinct.
Regulatory exposure

Regulatory exposure

Under regulation, an unprovable number is a finding. Lineage and proof that checks ran matter as much as the value.
Wasted compute

Wasted compute

Every record processed, stored, and moved before being discarded costs money an entry filter would have saved.
Project price

Project price

Our price follows datasets in scope, source condition, freshness needs, regulatory perimeter, and one-time versus running work, not data volume.

Evidence, Not Adjectives

Why Engineering Teams Choose Zoolatech

Leading data quality services for enterprises share one trait: a number somebody answers for. Judge the best data quality services, ours included, on the points here.
Thresholds as deliverable

Thresholds as deliverable

We deliver thresholds with owners, not dashboards. Zalando’s real-time customer data pipeline runs on that model today.
Business-critical data

Business-critical data

Our quality work runs on data that carries revenue: Zalando’s customer pipeline and a Fortune 500 retailer’s real-time data platform.
We fix sources

We fix sources

We change what produces the defect. On one job-processing platform, that meant instrumenting the whole job lifecycle.
Governed delivery

Governed delivery

Every engagement carries a dedicated delivery manager, a live risk register, and a formal QA gate before release.
Platform-neutral advice

Platform-neutral advice

We have shipped on Databricks, BigQuery, Synapse, and Teradata, so platform advice never arrives with a license attached.
Engagement Steps

How an Engagement Runs

You keep an artifact after every step, whether or not the next one happens. The baseline scorecard alone usually reorders your fix list.
Step 1

Scope the datasets that matter

We start from decisions, not systems: which reports the business runs on, and which datasets feed them. Artifact: a ranked scope with the reasoning behind the ranking.
Step 2

Scope the datasets that matter

We profile and score every dataset in scope on all six dimensions. Most teams have never seen quality as a number per dimension. Artifact: the baseline scorecard.
Step 3

Agree thresholds and owners

Each threshold comes from the decision the data feeds, not from what is achievable today, and gets a named owner. The gap between them becomes the remediation scope. Artifact: signed thresholds per dataset.
Step 4

Fix causes, not symptoms

Remediation runs on two tracks: correcting the data, and changing whatever produces the defect in the source system. Artifact: corrected datasets plus a record of the source changes.
Step 5

Instrument monitoring

Validation rules and threshold checks go into the pipeline and the monitoring stack, with routing to owners and a breach procedure. Artifact: the running checks and the escalation path.
Step 6

Run or hand over

Either we operate the thresholds as a managed service, or we hand them over to your team with documentation and a transition period. Artifact: the operating handbook.
Send us your dataset list. We map it onto the core steps.

Questions You May Have

What is data quality management?

Data quality management is the practice of defining what good enough means for each dataset a business depends on, measuring against that definition continuously, and fixing the causes when it is not met. A cleansing project is an action with an end date, while data quality management is a running state with a threshold, an owner, and a report.

How is data quality actually measured?

Data quality is measured across six dimensions, each with its own check: accuracy, completeness, consistency, timeliness, validity, and uniqueness. Each dimension gets its own score per dataset, because data can be perfectly accurate and three days too old.

What is a data SLO, and why does it matter here?

A data SLO states a threshold for freshness, completeness, and accuracy on a named dataset, with an owner accountable when it is missed, which is what turns a quality dashboard into a commitment. Without the threshold, measurement produces a number nobody owns, and quality initiatives stall after the first cleanup.

Is this a one-off cleanup or an ongoing service?

Both exist, but a cleanup alone rarely holds, because duplicates usually come from an input form and mismatches from two definitions. A remediation project fits when one dataset blocks something, and thresholds with monitoring keep it from regressing.

How is AI used in data quality work?

Models handle quality work that rules cannot: anomaly detection, entity resolution, validation of unstructured fields, and noise filtering, as on a media analysis platform where Amazon Bedrock with Claude and Titan filters incoming content. Models flag and route, while people still set the thresholds and own them.

Do AI and ML workloads need different data quality than reporting?

Yes: a report needs the numbers to be right, while a model needs the data to be representative. That adds coverage, bias across protected attributes, label quality, and distribution drift, so a dataset can pass every traditional check and still yield a model that fails where it matters.

What does bad data actually cost?

It costs in five ways: revenue lost to decisions made on wrong numbers, analyst time spent reconciling, decisions delayed by distrust, regulatory findings, and compute spent on discarded records. Only the first is visible, so the rest rarely reach a budget discussion.
