Data quality management (DQM) is a set of processes and practices that ensure data accuracy, consistency, completeness, and reliability throughout its lifecycle. It aims to enhance decision-making, operational efficiency, and customer satisfaction by providing high-quality data. Organizations employ DQM to ensure that their data assets are trustworthy and can be leveraged effectively for strategic initiatives.

Therefore, effective DQM is essential for maintaining competitive advantage and fostering stakeholder trust. However, many businesses fail to manage data quality due to a lack of awareness, insufficient resources, and insufficient commitment from leadership. This is where a set of data quality management best practices offers a framework for organizations to access their data quality needs and establish effective standards.

This blog discusses 6 data quality management best practices for businesses to maximize data quality in 2025.

According to a study by DiscoverOrg, sales and marketing departments in organizations lose approximately 550 hours and around $32,000 per sales rep from using bad data.

How to Manage Data Quality: 6 Best Practices for 2025

Here are the 6 data quality management best practices that will help you enhance data integrity and business performance:

1. Define Data Quality Standards

Defining data quality standards involves establishing clear and measurable metrics for accuracy, completeness, and consistency. Accuracy ensures that data correctly represents the real-world information it is meant to capture, while completeness ensures that all necessary data fields are filled in and none are missing. Conversely, consistency involves uniformity in data formatting and representation across different systems and platforms.

By setting these standards, organizations can create a benchmark for evaluating data quality, ensuring that expectations are well-defined and achievable. This process helps identify discrepancies and areas for improvement, fostering a culture of high data integrity and reliability throughout the organization.

What are Data Quality Management Standards?

Data Quality Management Standards are the guidelines and frameworks designed to ensure that data is accurate, reliable, and relevant throughout its lifecycle.

Here are some of the key data quality criteria:

Accuracy: Ensures that data is correct and free from errors.
Completeness: Data should be complete, with no missing values that could impact analysis.
Consistency: Data should be consistent across different databases and systems.
Timeliness: Data should be up-to-date and available when needed.
Relevance: Data should be applicable and useful for its intended purpose.

2. Implement Data Governance

Implementing data governance effectively creates a structured framework with clearly defined roles and responsibilities for managing data effectively. This framework includes assigning specific tasks to individuals or teams, such as data stewards or data custodians, who are accountable for maintaining data quality and compliance with established standards.

The governance framework ensures a structured oversight mechanism to monitor data practices, enforce policies, and address data-related issues. By having clear accountability and organized oversight, organizations can effectively manage data assets, safeguard data integrity, and ensure adherence to data quality and security standards.

According to a report by Dun & Bradstreet, around 41% of companies cite inconsistent data across technologies (CRM, Marketing Automa, Marketing Automation System, etc.) as their biggest challenge.

3. Audit Data Regularly

Regular data audits are essential for maintaining data quality and integrity. These audits involve periodic reviews of data to identify and rectify inaccuracies, inconsistencies, and potential issues. Data is examined against established standards and benchmarks during an audit to ensure it meets accuracy, completeness, and consistency requirements.

By catching errors early, organizations can prevent issues from compounding over time, thus preserving the reliability of their data. Regular audits also offer opportunities for continuous improvement by identifying trends and assessing the effectiveness of data management practices. This helps businesses make necessary adjustments to maintain high data quality.

How to Measure Data Quality: Key Metrics and Indicators

Here are the metrics that help businesses maintain reliable, actionable data for better decision-making and operational efficiency.

Accuracy Measures how closely data reflects real-world entities or values. For example, customer addresses should match official postal records. Regular validation against trusted sources ensures precision.
Completeness Evaluates whether all required data fields are populated. For example, a customer profile missing a phone number or email address would indicate incomplete data.
Consistency Checks whether data is uniform across systems or datasets. For instance, a customer's name should appear identically in billing, CRM, and sales systems.
Timeliness Assesses if data is up to date and available when needed. For example, outdated inventory records can lead to stock management issues.
Uniqueness Measures the absence of duplicate entries. For example, duplicate customer accounts in a database can distort analytics and reporting.
Relevance Determines whether the data aligns with business needs or objectives. For instance, retaining historical data that is no longer actionable can reduce efficiency.
Integrity Evaluates the logical structure and relationships within the data. For example, in relational databases, foreign keys must align with primary keys to ensure accuracy.
Validity Ensures data adheres to predefined formats and rules. For instance, a date field should only accept valid dates in a specific format (e.g., MM/DD/YYYY).

4. Implement Data Validation Rules

Data validation rules are one of the essential data quality management techniques for ensuring the accuracy and reliability of data during entry. These rules include checks and constraints that verify the correctness of data before it is recorded in the system. For instance, validation rules can enforce data format requirements, such as date formats or numerical ranges, and prevent invalid or incomplete data from being entered.

By applying these rules at the point of entry, organizations can significantly reduce the likelihood of data errors and inconsistencies. This proactive approach helps maintain data quality from the outset and helps prevent problems that could arise from incorrect or incomplete information.

Data Quality Frameworks

Here are some of the data quality frameworks:

ISO 8000: International standard for data quality, focusing on data quality in various contexts.
DAMA-DMBOK: Data Management Body of Knowledge, which includes principles & practices for data quality management.
CMMI: Capability Maturity Model Integration, which includes processes for improving data quality.
Six Sigma: A methodology that can be applied to improve data quality through statistical analysis and process improvement.

5. Cleanse Business Data

Data cleansing is the process of regularly updating and correcting data to maintain its accuracy and relevance. This involves identifying and removing duplicate records, correcting inaccuracies, and updating outdated or irrelevant information. Effective data cleansing ensures that the data remains clean, accurate, and useful for decision-making.

Regularly scheduled cleansing activities prevent data decay and ensure that the information used for analysis, reporting, and other business activities is current and reliable. By maintaining a high standard of data quality, organizations can boost their operational efficiency and make more informed decisions based on accurate data.

How do businesses manage customer data?

Businesses manage customer data through robust data governance frameworks that include data collection, storage, and processing protocols. They use CRM systems to centralize information, ensuring data accuracy and consistency. Regular data cleansing and validation practices are implemented to eliminate duplicates and inaccuracies. Additionally, businesses prioritize data security and compliance with key regulations to safeguard customer information and maintain trust.

Organizations can foster a culture of data stewardship and accountability by providing employees with the knowledge and skills to adhere to best practices.

Well-trained employees are also more likely to follow established data quality procedures, contribute to data accuracy, and identify and report issues promptly. This proactive data quality best practice ensures that data quality is consistently upheld and integrated into daily business operations.

Data Quality Analysis Example

Data Quality Analysis involves evaluating data sets to identify issues affecting their quality. For example, consider a retail company analyzing its customer database. The analysis might reveal several issues: missing email addresses, inconsistent formatting of phone numbers, and duplicate records for the same customer.
To conduct this analysis, the company would first perform data profiling, examining the structure and content of the data. They might find that 15% of customer records lack email addresses, while 10% have inconsistent phone number formats. Additionally, deduplication processes could uncover multiple entries for the same customer, leading to overestimations in marketing campaigns.
Addressing these issues through data cleansing and standardization boosts the accuracy and reliability of the company's customer insights, targeted marketing efforts, and customer engagement.
