HRIS (Human Resource Information System)

An HRIS is the foundational technology of the HR function — the system of record for employee data, including personal information, employment history, compensation, benefits enrollment, time and attendance, and organizational structure. All other HR technology either feeds data into the HRIS or pulls data from it, making the HRIS the data hub that determines the accuracy of everything downstream: payroll, benefits administration, compliance reporting, and people analytics are only as reliable as the employee data maintained in the HRIS. The most critical HRIS governance practice is data entry discipline: single source of truth requires that employee records are updated in the HRIS whenever a change occurs — title changes, salary adjustments, manager changes, leave status updates — rather than being maintained separately in other systems that diverge over time.
