Selected anonymised case studies
The cases below are anonymised, but the failure modes are real and representative of the kinds of structural data integrity problems that appear in practice.
Dropped Records in a Multi-Layer Data Journey
A subset of expected records failed to arrive across a multi-stage pipeline. Downstream systems continued to operate, creating the appearance of stability while the monitored population was already incomplete.
What mattered: proving the expected population, not just validating what arrived.
Transformation Correctness: Silent Corruption
Data remained populated end to end, but key values were changed by mapping and transformation logic. The issue was not loss of data, but loss of meaning.
What mattered: separating correctness from completeness and placing controls on semantic integrity.
Ownership Data Integrity (UBO)
Ownership information required for downstream use was inconsistent, incomplete and weakly governed across sources. The operational issue was visible, but ownership of the integrity question was fragmented.
What mattered: clarifying governance, lineage and control accountability rather than only enriching the dataset.
Third-Party Feed Onboarding and Drift
An externally sourced feed entered production successfully, but control coverage weakened over time as assumptions changed and drift was not challenged with enough discipline.
What mattered: sustained evidence and challenge after onboarding, not only initial implementation confidence.
Critical Process Data for Operational Resilience
Important process and dependency data required for resilience decision-making was present in parts, but not sufficiently complete or controlled to support credible executive assurance.
What mattered: making decision-support data provable, not just available.
Collateral / Asset Movement Data Assurance
Data relating to asset movement and status carried real exposure, but breaks emerged across hand-offs, with downstream teams inheriting uncertainty they could not fully explain.
What mattered: control design across the journey, not isolated checks within one platform.
What these examples say about DQIntegrity
Root-cause orientation
The work focuses on where integrity breaks actually originate, not only where symptoms become visible.
Control-led remediation
The response is structured around proof, controls and ownership rather than generic clean-up language.
Boardroom translation
Technical issues are reframed into decision, governance and exposure language that leadership can act on.
Structural consistency
Different mandates often reveal the same recurring patterns underneath: weak proof, late discovery and fragmented ownership.
Typical patterns across mandates
- Downstream symptoms with upstream causes.
- Stable outputs masking incomplete or distorted populations.
- Ownership fragmentation across systems, platforms and functions.
- Confidence in activity without equivalent confidence in evidence.
- Need for clearer control language at executive level.
