HR analytics is a data-driven perspective on human resource management. It is also defined as workforce planning, process metrics, or talent analytics, focuses on studying people issues and using the information to analyze important questions about your company. This allows for more informed and data-driven planning.
It does not look at all to collect information on how your workers perform at work; rather, its main purpose is to focus on providing a good understanding of each of your human resource processes by collecting appropriate information and then using that data to guide recommendations about how to enhance them.
 Why is it necessary to use a specific form of analytics when most businesses already have data that is frequently gathered? Isn’t it possible for HR to just look at the statistics they have had?
However, original data should offer some valuable information on its own. That would be like staring at a giant worksheet with a lot of statistics and text.
The information is defined as worthless and lacking organization or purpose.
This raw data becomes usable once it has been arranged, contrasted, and analyzed.
