Which example illustrates a primary function of a human resource information system?

The primary function of a human resource information system (HRIS) is to streamline and enhance various HR-related processes through effective data management. In this context, the most suitable example is determining employee promotions based on performance evaluations. This function illustrates how an HRIS can utilize data to support important decisions regarding employee advancement.

Performance evaluations are often documented within an HRIS, allowing HR professionals to analyze trends, track employee achievements, and inform promotion decisions. This demonstrates the system's ability to manage valuable employee data, which is critical for making informed decisions about workforce development and talent management.

While tracking employee attendance and vacation requests, conducting performance interviews, and managing employee health insurance plan selections are all integral functions of HR, they primarily focus on operational tasks or direct employee management rather than the strategic functions of promoting talent based on performance data. The choice involving promotions reflects a more strategic and decision-oriented use of HRIS capabilities, highlighting its role in supporting organizational growth and employee development.
