The True Cost of Poor Data Quality | IBM
Poor data quality doesn't just affect reporting--it can limit the value of AI, increase operational costs, and impact business decisions. This IBM article explores why trusted, high-quality data is becoming a competitive advantage for organizations embracing AI. Connect with Westwood Associates Ltd to discuss how strong data foundations can support successful AI initiatives.
Why does poor data quality matter more in the age of AI?
Poor data quality has always been a problem, but AI and AI agents make its impact much more visible and costly.
According to IBM Institute for Business Value (IBV) research, 43% of chief operations officers say data quality issues are now their top data priority. More than one-quarter of organizations estimate they lose over USD 5 million per year because of poor data quality, and 7% report losses of USD 25 million or more.
There are a few reasons this is intensifying:
- AI amplifies data issues: AI systems and agents inherit whatever is in the data. If the data is inconsistent, incomplete, biased, or outdated, models become less accurate and can spread those issues at scale.
- Continuous interaction with data: Modern AI agents don’t just use data at training time. They rely on it in real time to ground responses, trigger actions, and inform decisions across the business.
- Higher financial stakes: AI spending is accelerating and is forecast to surpass USD 2 trillion in 2026, with about 37% year-over-year growth. As AI investment grows, the cost of bad data grows with it.
Organizations that treat data quality as a core operating model—not a one-off clean-up exercise—are better positioned to move AI use cases from pilot to production and sustain value over time.
What does poor data quality look like in practice?
Poor data quality isn’t always obvious at the point where data is created. It usually shows up later as business problems, which makes it easy to underestimate.
Common indicators include:
- Inconsistency across sources: The same customer, product, or transaction looks different in different systems.
- Missing or incomplete data: Key fields are blank or partially filled, leading to duplicate records or gaps in reporting.
- Outdated information: Decisions are made on data that no longer reflects reality.
- Unclear ownership: Datasets can’t be traced back to accountable data owners, making issues hard to resolve.
These issues translate into tangible business impacts:
- Misguided decisions: Dashboards and BI tools built on inaccurate or incomplete data can lead to mispriced offerings, misjudged performance, or initiatives based on flawed assumptions.
- Weaker AI and automation: Machine learning models and AI agents trained or grounded on poor data propagate inaccuracies and biases across downstream systems.
- Lost productivity and trust: Data teams spend more time reconciling data silos than advancing new initiatives, and business users start to question the insights they receive.
- Compliance and risk exposure: In regulated environments (for example, GDPR or healthcare), inaccurate or poorly governed personal data can trigger audits, fines, and reputational damage.
Real-world incidents underline the cost:
- Unity Technologies reported about USD 110 million in lost revenue after inaccurate data ingestion corrupted datasets used for advertising-related machine learning models.
- Equifax issued incorrect credit scores to millions of consumers due to bad data from a legacy system, leading to regulatory scrutiny, litigation, and financial penalties.
- Samsung Securities suffered market disruption and an estimated hundreds of millions of dollars in market value loss after a single invalid data entry triggered the issuance of billions of duplicate shares.
These examples show how seemingly small data issues can reshape outcomes across analytics, AI, and core business processes.
How can we make our data AI-ready and reduce data quality risk?
Making data AI-ready means moving from one-off clean-up projects to a consistent, scalable approach to data quality across the full data lifecycle.
Key practices include:
- Establish strong, adaptive governance: Go beyond static policies. Align data ownership, lineage, metadata, and quality controls with how your data actually changes over time. This helps AI applications and agents “know” which data they can trust.
- Detect and monitor issues in real time: Instead of relying only on warehouse checks or batch profiling, use streaming observability, automated anomaly detection, and schema-drift monitoring to catch issues as they emerge.
- Automate correction and remediation: Manual cleansing can’t keep up with modern data volumes. AI-assisted remediation—such as automated deduplication, format standardization, rule generation, and self-healing pipelines—reduces human overhead and fixes issues earlier.
- Validate data at the point of entry: Embed quality checks into ingestion pipelines, APIs, and event streams so incorrect or incomplete data never reaches production systems. This “shift-left” approach is especially important when autonomous agents or real-time decisioning rely on that data.
To understand the impact of these efforts, many organizations track metrics such as:
- Frequency and severity of data incidents (how often issues occur and how disruptive they are).
- Mean time to detection (MTTD) and mean time to resolution (MTTR) for data issues.
- Delays to analytics and AI initiatives caused by data clean-up and rework.
By treating data quality as a prerequisite for AI success—not just a safeguard against risk—you can reimagine how data supports your AI roadmap, improve trust in insights, and get more predictable returns from your AI investments.
