Conclusion:
Human Resource Information System (HRIS) is a computer-based system that functions to manage, analyze, and manage human resources in order to obtain precise information for decision making.
It was also observed that two groups of organizations lead the HRIS implementation trend: the parent companies, with regard to their subsidiaries, and the largest firms in terms of number of employees. This seems a logical finding because their more complex structures may benefit more of the advantages of HRIS to increase the efficiency of their recruiting processes.
Besides, HRIS are found to be preferred in combination with other HRM practices, instead of on their own. This reveals that human judgment is still the main criterion for making decisions in this area, albeit assessed or supported by the information provided by the HRIS.
As for the main hypotheses tested in this research, internal recruitment is the favorite method for filling in vacant positions within the firms, which confirms the theoretical assumptions that asserted that, even though both internal and recruitment strategies are to be considered, the former is less costly and provides more advantages to the firms. Indeed, the evidence supports that a better performance is expected from the people internally recruited, which in turn will improve the overall business performance.
