A human resource information system (HRIS) is software that allows companies to manage human resources functions like employment records, performance reviews, compensation, and benefits. While not all companies use an HRIS, there are benefits to doing so like reporting capabilities and recruitment tools. An HRIS collects employee data that can then be used to generate detailed reports on topics such as hiring practices, salaries, or performance reviews. It also enables online job applications and resume searches. However, some disadvantages are that the system may be costly to implement and maintain, require training to use properly, and take time to set up, potentially going over deadlines.
