Final answer:
In implementing a new HRIS, HR, IT, Finance, Accounting, and Sales departments should all be involved in the decision-making process to ensure the system aligns with the organization's goals and integrates well with existing systems.
Step-by-step explanation:
When considering the implementation of a new Human Resource Information System (HRIS), various functional areas play integral roles in the decision-making process. The HR department is central to this process as the system will directly support their workflows related to hiring, managing employee records, payroll, and benefits administration.
However, Information Technology (IT) is equally important as they ensure that the HRIS integrates well with existing systems and meets the technical requirements of the organization. Additionally, Finance and Accounting may be involved to assess the cost implications and return on investment, while Sales could provide insights on how the HRIS might impact sales force productivity or client management. All of these functional areas should work in collaboration to ensure that the chosen HRIS supports the organization's strategic goals and operational needs.
