Imagine building a skyscraper on a shaky foundation—it wouldn’t take long for the structure to falter. The same concept applies to data. Data quality is the bedrock of every strategic decision, operational move, and insight-driven action within an organization. With high-quality data, businesses can stand firm, adapt quickly, and innovate confidently. But poor data quality is like working on sinking sand, leading to misinformed decisions, wasted resources, and lost opportunities.

In today’s digital world, the volume of data is doubling every two years, and 95% of organizations cite managing untrustworthy data as a significant barrier. According to Gartner, poor data quality costs companies an average of $15 million per year. This includes costs from inaccurate decision-making, regulatory fines, and inefficiencies. The challenges are clear, but so is the solution: investing in data quality is no longer optional—it’s essential for survival and growth.

What is Data Quality? Simplified for Clarity

Data quality is about ensuring that data is accurate, complete, consistent, and reliable—essentially, data we can trust. Here’s an analogy: think of data as ingredients in a recipe. Just as fresh, high-quality ingredients yield a delicious meal, quality data enables effective business operations and strategies. When data is trustworthy, it acts as a catalyst for success, helping businesses reach their goals, make informed decisions, and deliver value to customers.

Now, why is this important in simple terms? Well, imagine you are trying to make an important decision for your business, like launching a new product or entering a new market. If the data you are using is inaccurate, incomplete, or inconsistent, your decision may be based on faulty information, leading to poor outcomes and financial losses. On the other hand, good data quality ensures that the information you rely on is accurate, complete, and consistent. It helps you make more informed decisions, improve operational efficiency, and save costs by avoiding mistakes and rework.

Moreover, good data quality gives organizations a competitive advantage. By having reliable data, you can better understand your customers, identify market trends, and spot new opportunities. This helps you stay ahead of your competitors and make strategic moves that drive business growth.

Data quality will become more proactive, with automated processes detecting and resolving issues in real time.

The impact of poor data quality is like flying a plane with faulty instruments—no matter how skilled the pilot, unreliable data can lead to disastrous consequences. In business, this translates to project failures, financial setbacks, and missed opportunities. For example, imagine a company launching a new product using outdated customer data; they might target the wrong audience, waste marketing dollars, and lose competitive ground. According to Gartner, 40% of business initiatives fail due to poor data quality, while 12% of a company’s revenue is typically lost due to data errors. This equates to an average loss of $15 million each year. Remarkably, nearly 60% of companies don’t even track these costs, which is like running a factory without monitoring energy waste.

Forrester Research adds another layer to the story: less than 0.5% of all data is ever analyzed or used. Think of this as keeping a warehouse full of unused supplies, only to run out of stock for essential items (Forbes Article)

According to Forrester senior analyst Richard Joyce, if a Fortune 1000 company increased data accessibility by just 10%, it could generate over $65 million in additional income. These figures remind us that data quality isn’t just a technical concern—it’s the bedrock of strategic advantage.

As our data environments grow more complex, traditional methods of ensuring quality just can’t keep up. I believe the future of data quality lies in Generative AI and automated Data Quality (DQ) rules. Generative AI can process massive datasets, detect patterns, flag errors, and even propose new rules, making the DQ system more intelligent and self-improving over time. With automated rule creation, AI not only spots errors in real-time but also suggests corrections, allowing us to act fast and reduce risks significantly. Automated DQ rules continuously monitor our data—catching duplications, gaps, or anomalies 24/7, resulting in fewer errors and a 50% reduction in quality-related rework. What’s remarkable is how Generative AI learns with every data interaction, adapting DQ rules for more accuracy and scalability, much like a quality control assistant that evolves alongside our business

WHAT IS GOOD DATA QUALITY?

Good data quality means having reliable and accurate data. It should be complete, consistent, and relevant to its purpose. The data should be free from errors, trustworthy, and up-to-date. It should also follow defined rules and standards. There are a few factors through which we can measure the quality of the collected data:

• Accuracy: The data collected should have correct details. Incorrect data entries must be identified, documented, rectified, or removed if need be so that the system remains efficient.
• Completeness: The data entries must be complete to provide all adequate information. If there’s a database for employee information, details regarding personal and professional data must be completely mentioned
• Consistency: Consistency ensures that the same data at different locations match each other, i.e. no two records belonging to the same object should have different values. E.g. if we have two databases for employee data belonging to different departments, where in one department date field records are entered in the format DD/MM/YYYY, and in the other, it is entered in the format MM/DD/YYYY. Collecting data from both databases will result in inconsistency and hence a standard format must be selected.
• Reduced Redundancy: Redundancy exists when there’s a duplicity of data. We need to make sure our data collection is free from such unwanted, extra, and repeated information that won’t add value to our system.
• Uniqueness: Uniqueness is a result of removing redundant data, i.e. to ensure the data collected is distinct and desirable to our system.

WHY IS DATA QUALITY IMPORTANT?

Consider this: 73% of executives say they’ve made significant decisions based on faulty data at least once. Imagine planning a product launch based on inaccurate sales data—this could result in wasted marketing spend, misallocated resources, and a potential loss of market position. Conversely, quality data enables decision-makers to act with confidence, driving operational efficiencies, improving customer experiences, and enhancing financial outcomes.

When data is of good quality, it means we can trust it to make better decisions. Reliable data helps organizations work more efficiently, avoid costly mistakes, and keep customers happy. It also ensures that organizations follow rules and regulations to protect people’s data. By focusing on data quality, organizations can gain an edge over competitors and make smarter choices for success. The answer to the question Why data quality is important? lies in the following points:

1. Good data quality helps in conducting favorable data analysis: The main aim is to improve the quality and accuracy of the analysis performed, which is possible only if the data used is up to the mark.
2. Improved decision-making: As a result of refined analysis using relevant data, decision-making also improves.
3. Reduced efforts in identifying and rectifying errors: Ensuring data is of good quality makes it less prone to errors and reduces the cost, time, and efforts required to identify and remove them.
4. Helps avoid process breakdowns: Using unprocessed, rough, and unfiltered data can result in undesired and inappropriate results. This can hamper decision making, the functioning of certain operations and decrease the overall revenue of an organization.

DETERMINING DATA QUALITY

We learned how important it is to maintain data quality and how it affects not only data collection but also the subsequent data analysis process which is crucial for decision-making. Let us now see how data quality can be determined:

1. Poor data quality analysis: The first step is to analyze issues reported by testers and users. Analysts need to understand unwanted data characteristics and layout data quality requirements which will help in organizing the data further.
2. Data Profiling: Next step is to analyze what kind of data the organization requires for analysis, i.e. to understand the problem statement and identify the type of data which will be beneficial.
3. Understanding Quality Criteria: Analysts have to come up with methods to measure data quality, create acceptability standards and evaluate its business impact.
4. Setting up Data Management rules: Valid rules and definite standards are agreed upon and set up for data quality measurement.
5. Practical Application: One of the most important steps in maintaining data quality is to implement the above-decided convention into practice.
6. Data Monitoring and Updates: Updating the progress and continuously monitoring the process for its smooth and systematic execution.

CHALLENGES FACED DURING DATA QUALITY MAINTENANCE

1. Dividing Responsibilities: It is important to divide roles and responsibilities among the team members. Deciding who will be responsible for strategic activities, who will take in-charge of execution activities, and who will organize and manage operations is crucial and can be strenuous.
2. Recognizing Data Quality Issues: The members need to correctly identify which data is valid and separate it from the invalid data. Correct standards for data quality must be followed in order to collect an ordered set of data.
3. Managing Teams: The whole process is a task of numerous teams working together. The data architects, engineers, testers, and solution architects, everyone should communicate with each other with full transparency and report to each other about their progress.
4. Monitoring efforts: Be it time, cost, or manual labor, it needs to be monitored and tracked for progress. It is important to set KPIs (Key Performance Indicators) in order to carry on the process smoothly.
5. Maintaining Organization: There must be understanding and trust among the different teams that work for data quality assurance. Communication is a must for the proper and orderly execution of tasks.

Automated data quality solutions, including Generative AI and machine learning models, are becoming increasingly essential in tackling this challenge. These tools help identify inconsistencies in real time, propose standardized formats, and enforce quality rules across systems, allowing organizations to achieve cleaner, more reliable data without extensive manual intervention.
