May 3, 2024

In today's digital age, data has become a critical asset that guides the direction of businesses of all sizes. Organizations rely on data to gain insights into customer behavior, improve operational efficiency, and make informed business decisions. However, the value of data is only as good as its quality and reliability. 

Poor data quality and reliability can lead to incorrect or incomplete analysis, which can have serious consequences for the business. Hence, mastering data quality management has become imperative for businesses aiming to harness the full potential of their data assets.

Continue reading the article to explore the data quality management framework and best practices that businesses can use to improve the quality and reliability of their data.

What is Data Quality Management?

Data Quality Management includes a specific set of practices that can enhance the quality of data being utilized by businesses. 

Research has repeatedly demonstrated that poor data quality management has cost businesses millions of dollars. In 2016, IBM released a report that estimated the cost of bad data for U.S. businesses was around $3.1 trillion dollars every single year. Over time, as businesses continue to manage increasing volumes of data, that number is only likely to go up. The question is, can we solve the problem?

Data Quality Management is the answer. At its core, data quality refers to the accuracy, completeness, consistency, timeliness, relevance, and validity of data. Each of these dimensions plays a crucial role in ensuring that data can be trusted and utilized effectively for decision-making purposes.

  • Accuracy: It measures how closely data reflects the real-world objects or events it represents. Inaccurate data can lead to faulty analyses and misguided decisions.
  • Completeness: In data quality, completeness refers to whether all required data is present. Incomplete data sets may skew analyses and hinder comprehensive insights.
  • Consistency: It helps to ensures that data is uniform and coherent across different sources and systems. Inconsistent data can result in discrepancies and confusion.
  • Timeliness: This aspect of data quality indicates whether data is up-to-date and relevant for the task at hand. Outdated data may lead to obsolete insights and missed opportunities.
  • Relevance: It assess the appropriateness of data for a given purpose or context. Irrelevant data can distract from meaningful analysis and decision-making.
  • Validity: This determines whether data conforms to predefined rules and constraints. Invalid data can compromise the integrity of analyses and undermine trust in the data.

Challenges in Data Quality Management

Despite its importance, organizations faces various data quality issues. Maintaining high data quality poses several challenges like:

  • Data Duplication: Duplicate records can proliferate across databases, leading to inconsistencies and inefficiencies.
  • Inconsistent Data Entry: Human error during data entry processes can result in inconsistencies and inaccuracies.
  • Lack of Data Standardization: The absence of standardized formats and conventions makes it difficult to integrate and analyze data effectively.
  • Data Silos: Data stored in isolated systems or departments inhibits collaboration and hampers data quality efforts.
  • Poor Data Governance: Inadequate governance structures and processes weaken accountability and oversight of data quality initiatives.

Best Practices for Data Quality Management ‍

The increase in the demand for data in the contemporary digital age has led to a remarkable challenge - a data crisis. It results from poor-quality data which makes it unusual or unreliable for businesses. Data Quality Management prevents these crises from occurring by providing a quality-focused foundation for an enterprise’s data. 

Data Quality Management has become an essential process that helps businesses to make sense out of data. It helps to ensure that the data present in systems is appropriate to serve the purpose. Here are the best practices for data quality management.  

Assessing Data Quality and Reliability

The first step towards improving data quality and reliability is the assessment of the current state of your data. You can start by identifying the sources of the data, which includes both internal and external sources, such as customer data, sales data, and third-party data. Once you identify your data sources, you can evaluate the data for completeness, accuracy, consistency, timeliness, and validity. This will help you identify areas for improvement and develop a plan for data cleansing and normalization.

Data Governance

This practice in data quality management plays a critical role in maintaining data quality and data reliability. It involves establishing a data governance program to ensure proper management, security, and quality of data. This includes developing policies and procedures for data management, assigning roles and responsibilities, and ensuring compliance with relevant regulations and standards.

Data Cleansing and Normalization

One of the most effective ways to improve data quality and reliability is through data cleansing and normalization. This involves identifying and correcting errors and redundancies in data, standardizing and normalizing data formats and structures, and removing duplicates. Data cleansing and normalization can improve data accuracy, consistency, and completeness, which are essential for reliable data analysis.

Data Integration and Migration

Integrating data from multiple sources and migrating it from legacy systems can be a complex process. However, it's essential to ensure data quality during integration and migration to avoid data inconsistencies and errors. This involves selecting appropriate tools and technologies for data integration and migration, testing and validating data before and after migration, and ensuring data security during the process.

Training and Education

Finally, training and education play a crucial role in maintaining data quality and reliability. It's important to train employees on data management and governance best practices and provide ongoing education to keep them up-to-date with new technologies and regulations. Sharing best practices for maintaining data quality and reliability can also help organizations avoid common pitfalls and ensure maximum value from their data assets.

Data Quality Management Framework

An effective data quality management framework is comprehensive and covers all of the six main pillars of data quality we have already mentioned. It should cover the entire data cycle from the source to the analysis by end-users and everything in between. This includes establishing policies that manage the handling of data. Over 70% of employees currently have access to data they should not be able to see. Solving problems like this is impossible without having solid data observability. 

For example, Acceldata gives you the ability to automate much of your data quality management with an AI system that is able to improve dynamic data handling and detect invisible errors such as schema and data drift. Referring to a data quality framework implementation guide is often a great way to learn more about the particular checks you should have in place to ensure that your data quality is effectively managed. 

Data Quality Management Examples

We’ve discussed much of the theory surrounding good data quality management. However, from a practical perspective, what does this process actually look like? What are some data quality management examples? One great example of data quality management is data profiling. Data profiling is the process of monitoring and cleaning up data to enable organizations to make better, insights-driven decisions. 

Traditionally, data profiling is a complex, time-consuming task requiring hours of manual labor. However, with Acceldata, you can introduce automation into the process, freeing up your teams to focus on analysis and decision-making instead of cleaning and organizing. Other data quality management examples include smart data handling policies and data validation tasks. 

Acceldata enables you to get the context you need with machine-learning-based classification, clustering, and association. Plus, it offers a dynamic recommendations feature that can help you rapidly improve data quality, accuracy, coverage, and efficiency.

Good data quality starts with a data quality management definition. This definition should have buy-in from your company’s top leadership. The framework you build and implement needs to clearly define the data quality management roles and responsibilities as well. Furthermore, your plan should also describe the kinds of data quality tools that are going to be used.

Future Trends in Data Quality Management
