In PeopleSoft HCM, the PeopleSoft Business Partners feature lets you define specific people in your organization to serve as Human Resources liaisons for groups of employees. You can define groups by work location, business unit, department, job, last name, or any other criteria. The liaisons, or business partners, can be HR generalists or specialists like payroll business partners, benefits business partners, etc. If you have a shared HR service center model, you can define your organization's HR representatives and define the employees they serve.
