How Dirty Data Could Be Draining Your Business: Lessons from the Trenches

If you are yet not afraid of messy data, let us begin some brief management horror stories.

In 2015, retail giant Target faced one of its most significant failures when attempting to expand into Canada. A critical supply chain mismanagement issue led to the abrupt closure of 133 stores (source: Talking Logistics). Just two years later, in 2017, Uber, a world-leading on-demand cab service, miscalculated driver payouts, resulting in an estimated USD 45 million in refunds (source: Montecarlo Data). That same year, All Nippon Airways suffered a costly currency conversion error, allowing customers to purchase tickets at up to a 95% discount, causing financial losses worth thousands of dollars (source: Bloomberg).

What do these incidents have in common? Bad data.

These examples illustrate how poor data management can have costly consequences for businesses. Imagine an online retailer shipping orders to incorrect addresses due to duplicate customer records or a bank approving loans based on outdated credit scores. These aren’t minor setbacks - they lead to financial losses, wasted resources, and damaged customer trust.

Clean data - accurate, complete, and properly formatted - is the foundation of smooth business operations. And if you want to know more about it, this article is what you are looking for.

1. Clean data: definition

High-quality data enables businesses to make informed decisions with confidence. But what exactly constitutes clean data?

Five fundamental elements can be seen as the data quality, which the Data Management Association defines as “the degree to which data is accurate, complete, reliable, and relevant to the purpose for which it is used”. As early as 1996, Thomas C. Redman defined clean data as:

• Accurate: correct and error-free
• Complete: avoiding missing and incomplete information
• Consistent: being homogeneous across all business systems
• Valid: conform to predefined formats and rules
• Updated: keeping up with time and being ready to use when needed

A decade later, in 2016, Redman estimated in the Harvard Business Review that bad data was costing businesses a staggering USD 3 trillion annually, a clear indicator that high-quality data isn’t just an IT issue - it’s a strategic business decision that impacts every level of an organization.

2. The twofold benefit of clean data

Clean data offers two key advantages for businesses:

• Improved operational efficiency
• Enhanced customer experience

In fact, by minimizing errors, reducing redundancies, and streamlining processes, clean data supports smoother workflows and better decision-making. Simultaneously, it helps create more personalized and reliable interactions with customers, fostering long-term loyalty and engagement.

Let’s delve into it a bit deeper.

Operational efficiency is another key advantage. Clean data minimizes redundancies, reduces processing errors, and ensures seamless workflows. As highlighted in our Global Data Solutions article, 69% of practitioners report bad data directly harming their activities (PR Newswire). For logistic-based businesses in particular, a Loquate report found that “address inaccuracies derail a staggering 80% of deliveries, causing costly delays (41%) and tout-court failures (39%)” (DataHub.io).

Beyond analytics, clean data enhances customer experience. Duplicate records, incorrect addresses, or outdated contact details lead to frustration and lost revenue. According to Salesforce, 94% of businesses believe that maintaining clean data improves customer engagement. Organizations that prioritize accurate customer databases reduce churn, streamline personalized marketing efforts, and foster long-term loyalty.

As shown by the experiences of businessmen and experts, ensuring data quality is not just a technical necessity but a strategic imperative. And, given so, there is no wonder why data are the new gold.

3. How to ensure clean data

Maintaining clean data requires the implementation of effective validation techniques. But what are the specific practices to perform the task?

• Data Validation: Implement rules like format checks, range constraints, and consistency checks at the point of entry to catch errors early
• Regular Audits: Conduct periodic data reviews to identify inconsistencies, outdated information, and redundancies that could impact business decisions
• Deduplication: Merge duplicate records to maintain a single, accurate representation of each entity and prevent inefficiencies
• Standardization: Use uniform data formats, naming conventions, and entry protocols to ensure consistency across all systems
• AI-Powered Cleansing: Leverage machine learning algorithms to detect patterns, correct errors, and maintain data accuracy over time

Among these practices, data validation and AI-powered cleansing are the most common and efficient. However, these methods work best when combined, particularly under the guidance of a specialized professional team.

Why? Because, by integrating these best practices, organizations can enhance data quality, improve analytics, and build a strong foundation for business growth.
