I have a good deal of experience in digital transformation, implementing data analytics systems for different business purposes. HR is probably a laggard in what digital concerns, but it's undergoing big transformations nowadays.

You might want to start your search by looking at Applicant Tracking Systems (ATS) for example. Even though acronyms and terms may vary in different regions, you'll find tools that allow you to measure a wide range of data in the recruitment business. There's several benefits to take out of these tools, ultimately leading companies to save hundreds of thousands dollars in recruitment activity, and considerably reducing their resourcing staff.

Feel free to get in touch if you'd like to know more about that.
