Common Data Quality Issues and How to Fix Them

Enterprises heavily rely on data to make decisions, formulate strategies, and forecast. Nonetheless, low-quality data may give way to expensive errors. Learning to identify the main issues with data quality and address them properly is vital to establishing trust in your analytics and views.

5 Most Common Errors In Data Quality 

A proactive approach makes business decisions based on the insights that are not only trustworthy but also actionable. Here are some of the most common data quality issues and how you can fix them.

Inaccurate data

Errors can be made during manual data entry, in old systems, or during incorrect data transfer, leading to inaccurate records. This has the capacity to pervert decision-making. Automate data validation rules and frequently audit all of your data sources to spot inconsistencies as soon as they occur.

Incomplete data

Fields that have not been captured, like the contact details of the customers or transaction details, compromise the analysis. Standardize the practices involved in data collection and include required fields in the forms to reduce unstructured data collection.

Duplicate records

Duplicate data on the same entity skews the metrics and reporting. Consolidate/eliminate duplicate records using de-duplication tools and algorithms.

Inconsistent formats

Data in different formats is hard to integrate, including date formats (MM/DD/YYYY vs. DD/MM/YYYY). Develop a standardized data format policy and implement these policies on all systems.

Outdated data

Outdated addresses, expired product information, or dead accounts make the databases less reliable. Set up routines around update times as well, and make use of real-time synchronisation when possible.

Conclusion

Information can only be as strong as its qualifications and soundness. Addressing inaccuracy, incompleteness, duplication, inconsistency, and outdatedness, the organizations will be able to achieve significant improvements in data quality. Visit this website to learn more about quality data.
