Managing and organizing HR data is one of the most challenging tasks for CHROs and people operations managers. In HR analytics and decision-making, data quality is crucial. To make the right hiring, firing, promotion, etc. decisions, it is imperative to ensure employee data is accurate and complete.
Improving data quality is therefore an essential step to improve the accuracy of HR analytics. This post presents several methods that can be used to improve the quality of HR data. Implementing these methods in your organization will help to perform better and more reliable HR analytics.
HR departments are responsible for collecting and managing data. To ensure they can use that data to make informed decisions, they need to ensure the data is of good quality. The best way for HR departments to improve the quality of their data is to establish clear processes for collecting and storing it. That way, they can track history and provide the context in case information needs to be updated later. In addition, implementing automated data checks can help highlight discrepancies that could affect the accuracy of the analysis so that these issues can be quickly addressed. Ultimately, by improving the quality of their HR-related data, HR departments can be confident that their analytics are reliable and accurate, leading to better decision outcomes for all stakeholders in the long run.

HR data is essential to making informed decisions about your workforce, but it’s only as good as the quality of the data. If you want to improve your HR analytics and get better results, you need to invest in improving the quality of your HR data. By taking steps to improve data collection and increase accuracy, you can ensure that your HR analytics are based on clean, valid, and up-to-date data – giving you accurate insights and reliable recommendations.

At peopleIX, we use an algorithm that detects all your data quality issues within minutes and even gives you suggested values that you just have to accept. The errors detected by the algorithm include:
The data health algorithm does not simply identify all empty fields, as in the case of HR data, some fields may intentionally be left blank. The algorithm is designed to differentiate between intentionally empty fields and genuinely missing values by following logical rules. For example, if a person is hired but no offer date is entered, the algorithm recognizes that logically a value is missing in this field.
Duplicates refers to instances where there are duplicates or inconsistencies in the labels of the data. For example, if one employee has their nationality listed as “German” and another employee has it listed as “Deutsch,” it is important to merge and standardize these values into a single category.
Irrelevant values refer to a special case where specific data entries or individuals need to be excluded or treated differently during analysis due to their unique characteristics or circumstances. For example, you create 5 access accounts for external recruiters in your HCM/HRIS system. While these accounts are treated as employees in your HCM/HRIS system, they are not meant for the desired analysis and therefore should be excluded from data in the peopleIX platform.
The algorithm checks each data field for the format and has stored information about which data field is allowed to have which format. For example, an error is detected for the date if it contains letters.
For some fields, certain lower and upper limits are defined. For example, a data quality issue is detected if the age is below X or above Y years, as it is very likely that an error occurred here.
Once our algorithm has processed the data of all your applicants and employees, all detected data quality issues are listed in the peopleIX platform. You can then fix them within the shortest possible time, as our algorithm directly suggests the most likely correct values.
In addition, we provide you with a data health score for all metrics and dashboards. The data health score indicates how clean your data is. Its purpose is to give a quick overview of the reliability and accuracy of your data in a single metric. The score can range from 0 to 100, with a higher score representing better data quality. This allows you to always analyze the meaningfulness of each metric and dashboard in light of the data quality.
