Data quality management practices like cleansing and standardization can also help identify and remove sensitive data, reducing the risk of data breaches. Now that you understand data quality management and its importance, the next section will explain the techniques behind DQM and the five pillars supporting it.     

The 5 Pillars of Data Quality Management

While the implementation of small-scale and enterprise data quality management can vary, they both establish a common outline that maintains the data’s usability throughout its lifecycle. Here are the five essential pillars of an effective data quality management strategy:


Successful data quality management requires a collaborative team with diverse expertise. People at every level play their role in making this process as smooth as possible. Some of the roles and responsibilities are:

  • Chief Data Officer: A CDO is a high-level executive at your organization who provides strategic direction to enhance data utilization and oversees that data quality management initiatives meet business goals. 
  • Data Governance Team: This cross-functional group comprises representatives from various departments, such as IT, marketing, and finance, who establish data governance policies and oversee their implementation. They ensure your organization meets data quality standards.
  • Data Domain Owners: They are representatives with deep knowledge of specific data sets and their corresponding business processes. They define requirements and identify potential issues within their domain and datasets.
  • Data Architects: These IT professionals design and maintain the technical infrastructure supporting your data quality initiatives. They are crucial in integrating data quality tools and processes into existing data pipelines.
  • Data Consumers: Sales, marketing, product, and business development teams are considered data consumers. They rely on data in its raw form or as actionable insights to inform their decision-making processes. They also provide feedback on your data quality issues.  

Developing a collaborative environment with clear roles and responsibilities can help you build a strong DQM team that effectively manages and improves data quality.

Assessment Metrics

Just like any business process, data quality management requires measurable goals. Some of the important metrics are: 

  • Accuracy: It reflects how closely your data values represent reality.
  • Consistency: Ensures data uniformity across all your systems.
  • Completeness: Measures whether all necessary data points are present.
  • Timeliness: Indicates how recent and up-to-date your data is.
  • Uniqueness: Identifies and eliminates duplicate data entries.

Regularly monitoring these core metrics can help you better understand your data and identify the trends and patterns they project. 

Data Quality Management Techniques

Data quality management techniques are like a toolbox to keep your data clean and reliable. Here is a quick rundown of some key techniques:

  • Data Profiling: This data quality management technique involves analyzing your data’s structure, content, and relationships. You can also identify quality issues in the current state and redefine your requirements based on the business goals. 
  • Data Cleansing: It helps you address data quality issues by correcting errors, missing values, and inconsistencies, removing duplicates, or standardizing formats. 
  • Data Validation: This technique ensures your data conforms to predefined rules or standards by verifying its accuracy, consistency, and other metrics. 
  • Data Enrichment: Data enrichment involves adding additional information from external sources to your existing data to provide more context or value and improve its usability.
  • Monitoring and Reporting: Data monitoring tracks key quality metrics over time and notifies about deviations from predefined standards by providing alerts or generating reports. This allows you to take preventive measures before your data quality suffers. 

These data quality management techniques ensure that your data is high-quality and ready for use in business analytics and informed decision-making.

Structured Framework

A well-defined DQM framework provides a structured approach to data quality management. It outlines the key stages involved:
