The HR industry is in the midst of a digital revolution. HR professionals are now flooded with options for technologies — as evidenced by the more than $2 billion in investment capital raised for HR technology in 2015 — for everything from recruitment and performance management to learning, wellness and employee engagement.

This should be a welcome development to help resolve a disconnect in HR technology adoption: According to a survey of human resources and business leaders (Deloitte's Global Human Capital Trends 2016), 75 percent of respondents believe digital HR tools are an important priority, yet only 38 percent of companies are even thinking about digitalizing their HR tools, and only 9 percent are fully onboard with digital HR systems.

In order to stay relevant and recruit top talent, especially among millennials who are projected to make up 50 percent of the U.S. workforce by 2020, HR teams will need to partner closely with IT to keep pace with advancements in HR technologies.
