You use the resource pool to search for eligible candidates. Candidates are the nominated resources for open requirements. After the Oracle workflow approval, candidates work for a project.
The candidate life cycle begins with the search for candidates for open requirements. Candidates are nominated for requirements, their qualifications and competencies reviewed, and finally selected and assigned.
The candidates can also be assigned directly to fill the requirement. The team roles and staffing processes have some required and optional predefined behavior. You can define this default behavior through profile options, statuses, and other attributes.
