Weak data quality and poor observability can have devastating consequences, as evidenced by recent high-profile incidents that have severely impacted organizations. In February 2025, Citigroup mistakenly credited a customer’s account with $81 trillion instead of the intended $280. Although the error was identified and corrected within hours without financial loss, it highlighted significant operational vulnerabilities within the bank’s systems.
Similarly, a UK Treasury committee investigation revealed that major banks and building societies experienced over 33 days of IT failures between January 2023 and February 2025. These outages disrupted millions of customers’ access to banking services, emphasizing the need for enhanced data observability to prevent such occurrences.
These events highlight the growing need for both data quality and observability to ensure accurate, reliable, and continuously monitored data in modern business operations.

How Data Quality and Data Observability Work Together Organizations require both data quality and data observability to develop a strong and dependable data ecosystem. Data quality allows measuring if stored data is correct, while observability allows ensuring that data pipelines work well in all conditions and do not fail unexpectedly. Here’s how they complement each other:
1. Data Quality as the Foundation Data quality provides the foundation of reliable analytics, reporting, and compliance. Businesses that rely on such cleansed and structured data avoid basing their decisions on flawed data. Quality management processes (standardization, deduplication, and validation) ensure that data imports are accurate, complete, and appropriately formatted before usage.
For example, in financial reporting, ensuring consistent account numbers, transaction details, and timestamps is essential for compliance with regulations like SOX or IFRS. Without high data quality, reports could contain discrepancies that lead to audits or financial penalties.
2. Data Observability as the Watchdog Even when data is clean, issues can arise while it moves through pipelines. Data observability acts as a real-time monitoring system, continuously tracking data freshness, volume, and schema changes to detect problems before they cause damage.
For example, an e-commerce platform relies on real-time order tracking. If a data pipeline suddenly fails, order status updates may not reflect correctly, causing confusion for both customers and support teams. Observability catches these failures immediately, allowing teams to fix them before they escalate.
3. Proactive vs. Reactive Approach Data quality is reactive —it detects and resolves known problems like missing values, duplicate records, and formatting discrepancies. Data observability is proactive — it provides continuous systems monitoring, catching the unexpected such as sudden dip in data volume, schema mismatches, or even latencies, well in advance of their downstream impacts in business operations. For instance, a machine learning model predicting customer churn may rely on clean customer data (ensured by data quality) but could fail if a data pipeline silently drops 30% of customer records. Observability catches the issue in real time, preventing flawed model outputs.
4. End-to-End Data Coverage Data quality ensures that historical and stored data remains correct, while observability guarantees that live data flows correctly between systems. Together, they provide end-to-end data trust:
Quality checks stored data for accuracy before analysis. Observability monitors real-time processing and delivery, ensuring new data enters the system without corruption or delay.
For example, a company tracking sales data must ensure that both historical purchase records are correct (data quality) and new transactions are processed in real time without failure (data observability).
5. Preventing Data Downtime Data downtime — periods when data is missing, inaccurate, or unreliable which can lead to business disruption, revenue loss, and poor customer experiences . Observability proactively reduces downtime by pinging teams whenever problems occur, whereas data quality focuses on long-term correctness. Consider a cloud-based CRM system:
If data quality isn’t enforced, sales reps may deal with duplicate leads or incomplete customer profiles. If observability isn’t in place, a sudden data pipeline failure could mean that new customer interactions aren’t logged in, leading to missed follow-ups and lost revenue. By combining both, businesses can prevent data failures before they become costly problems.
6. Better Decision-Making Reliable data leads to better business decisions, more accurate AI models , and improved operational efficiency. When data is both high quality and continuously monitored, organizations can trust it for:
Customer insights and personalization in marketing.
For instance, an airline using AI to predict aircraft maintenance needs must ensure that:
Historical maintenance data is accurate and standardized (data quality). Data Visualization Tools: A Comprehensive Guide to Choosing the Right One Explore how to select the best data visualization tools to enhance insights, streamline analysis, and effectively communicate data-driven stories.

Financial Services – Fraud Detection and Risk Management Data Quality: Ensures that customer transaction data is accurate, complete, and standardized to detect fraudulent patterns effectively. Data Observability: Monitors real-time transaction flows to detect sudden spikes or anomalies that could indicate fraud. Use Case: A bank monitoring credit card transactions uses data quality processes to remove duplicate or incorrect entries while observability tracks unexpected transaction surges to flag potential fraud in real-time. 2. E-Commerce – Real-Time Order Processing and Inventory Management Data Quality: Cleans and standardizes product information, ensuring consistent SKUs, pricing, and descriptions across platforms. Data Observability: Monitors real-time order tracking, alerting teams if transaction data is missing or delayed. Use Case: An online retailer ensures that product catalog data remains accurate while using observability to track real-time order processing failures, preventing customer service disruptions. 3. Healthcare – Patient Data Integrity and Compliance Data Quality: Ensures that patient records are complete, structured, and meet regulatory compliance standards such as HIPAA. Data Observability: Monitors data pipelines to prevent delays in transferring lab results or medical history updates. Use Case: A hospital maintains accurate patient records through data quality processes while using observability to track real-time data transfers between healthcare providers, ensuring timely medical decisions. 4. AI and Machine Learning – Data Pipeline Reliability for Model Training Data Observability: Monitors data drift, missing values, or anomalies that could affect model performance. Use Case: A predictive analytics system in retail ensures that historical sales data is accurate while using observability to monitor real-time data feeds that update demand forecasts.
