Which Data Quality Standards Should Your Organization Adopt?

Data quality is a measure of the condition of data, based on these 6 data quality dimensions such as  accuracy, completeness, uniqueness, consistency, timeliness, validity, and integrity. Every year, due to poor data quality costs organizations an average of $12.9 million, this affects financial loss and reputation damage. As businesses highly rely on data for making informed decisions, poor data quality can lead to misguided data analytics, operational inefficiencies and flawed strategies. 

The goal of having high-quality data is to make data-driven decisions to improve business aspects. For example, a retail company has customer records with incomplete addresses. This results in undelivered packages and increased shipping costs, which in turn affect customer satisfaction due to delays in receiving orders. 

What are Data Quality Standards?

Data quality standards are guidelines and criteria used to assess data quality and ensure the accuracy, completeness, consistency, validity, integrity and reliability. Understanding the differences between these dimensions, such as data integrity vs data validity, is essential for implementing data quality standards that support accurate and reliable data usage across systems. Here are the 6 data quality dimensions standards:

1. Accuracy 

Data accuracy is one of the 6 dimensions of data quality standards, which refers to how well the data represents real-world entities or the true value it is meant to describe. High data accuracy is important for business as it results in strategic decisions; inaccuracies in data can lead to misguided analytical outcomes and unreliable business strategies. 

It helps organizations ensure compliance policies and procedures and also checks whether the data meets all the predefined standards before it is used for data analysis. Data accuracy tools such as Informatica Data Quality and IBM InfoSphere QualityStage improve an organization’s overall operational efficiency without wasting resources. In financial terms, data accuracy prevents misguided analysis reports and maintains investors’ trust. 

For example, consider a healthcare organization that maintains patient records. If a patient’s D.O.B. is incorrectly entered, this inaccuracy can lead to several issues, including medical decisions, compliance issues, or insurance claims. Overall, data accuracy plays a vital role in effective data management for analysis.

2. Completeness 

Data Completeness ensures that no essential data is missing, critical for accurate data analysis and decision-making.  Depending on the business entity, data completeness assesses whether all the required data are present and accounted for in a dataset. Completeness gives a full detailed picture of the subject matter, helping organizations to draw meaningful insights from the data.

An example is a customer’s middle name, which is not essential in deriving marketing strategies, where a customer’s age, demographic area are considered to be highly important to gather insights. This shows even if an attribute in a dataset is missing, the data is still considered complete. Maintaining data completeness requires data audits, reviews and validation processes.  Ultimately, every organization strives for complete data for better insights, good communication and good decision-making.

3. Consistency 

Data consistency refers to the perfect alignment of all the essential data present in a dataset, even if they are stored in different places, minimizing discrepancies that can ultimately lead to errors. In the data quality dimension, consistency is essential for data integrity maintenance, as it can impact the quality of data analysis reports and decision-making. 

Inconsistencies in data such as differing product prices across systems or different spellings of a customer’s name, can create serious operational difficulties and poor customer experience. Especially in healthcare and finance, maintaining data consistency is crucial as it helps in regulatory compliance. In many organizations, data governance frameworks and procedure are implemented to maintain data consistency 

4. Uniqueness 

Data uniqueness refers to the fact that each record in a dataset should be a distinct value and not duplicated. This attribute is essential to maintaining data integrity and accuracy. It also ensures that each entity, such as a customer’s transaction or a product, is represented only once in the dataset. This data quality dimension prevents data confusion and errors, which can arise from multiple entries. 

Uniqueness helps in data management and simplifies duplicate data complexities. To avoid data duplication, organizations often follow unique identifiers, such as product codes and customer IDs. Regular data audits or implementing data validation rules also help in identifying duplicates. 

5. Timeliness 

Timeliness refers to how up-to-date the data is when needed and its applicability to the current situation or conditions. For example, outdated sales figures could lead to overstocking or stockouts. It is crucial to maintain data, as outdated data can also lead to poor decisions and missed opportunities. 

Some key aspects of timeliness in data quality include updating the data frequently, minimizing latency, streamlining the processing speed to enhance timeliness. To consider a data for analysis, it must be relevant to the specific context in which it is used, implying that companies need to know how often to update their data 

6. Validity

This data dimension signifies the accuracy and reliability of the data for business requirements. It follows a certain format, to check the integrity and quality of data before it is used for business analysis. There are several ways to check data validation including data type, consistency check, uniqueness, format.

For example, many companies follow a certain age format for their customer database. An age field should be within a range and can only be a numeric value. In a logical range such as 0 to 130, an entry like “-1”  would be considered invalid. This logical error can lead to poor data analysis and financial loss. 

7. Integrity 

Data integrity ensures the accuracy, completeness, consistency and quality of data over its life-cycle. Maintaining data integrity across several formats can be difficult and complex, particularly when dealing with sensitive data like personally identifiable information (PII), including customer name, age, and address. When data is replicated or transferred, it should remain the same without being unaltered between data updates. 

Maintaining data integrity is important for several reasons, including data origin and connectivity. Data is likely to be generated from multiple sources, including historical or real-time data. Data integrity is important to improve the quality of business and data-driven decisions.

Inaccurate data leads to poor decisions, financial loss, and wasted effort and time. Several data integrity types are related to database management: entity integrity, referential integrity, domain integrity, and user-defined integrity.  

Data integrity can be compromised in various forms, including human errors ( accidental or unintentional), data transfer errors, cybersecurity threats, third-party integration, changes in data structure, software bugs.

Why are Data Quality Standards necessary for your organization? 

Data quality standards is essential for a company for several reasons:

• Informed decision-making: High-quality data guarantees that the information is trustworthy and correct, which supports the development of business strategies and customer trust.
• Data Consistency: Data quality standards promote data consistency across various datasets. This dimension of data quality enables better data integration from various departments, leading to better data insights.
• Increased customer trust: When the quality of data is standardized, follows all the regulatory compliance, stakeholders are likely to trust the data
• Enhanced customer experience: Accurate and high-quality data allows for personalized experiences and data insights, leading to customer loyalty.
• Reducing risk intensity: Poor data quality can lead to significant risks, including financial loss or reputation damage. Standardizing data integrity reduces risks.
