A category buyer responsible for managing the supplier lifecycle needs specific permissions to execute their tasks. The Supplier Registration Manager group grants the necessary rights to initiate and manage the supplier registration process, including reviewing and approving new supplier registrations. The Supplier Qualification Manager group provides the authority to create and manage qualification projects, evaluate suppliers against specific criteria, and consequently approve, qualify, or disqualify them. Assigning both groups provides the category buyer with end-to-end control over these critical initial phases of supplier management.

A. Preferred Supplier Manager: This role is focused on managing preferred supplier lists and statuses, a function that typically follows the initial registration and qualification.

D. Supplier Request Manager: This group manages the initial internal request to add a new supplier, which is a preliminary step before the formal registration process begins.

Supplier Registration Manager: "Members of this group manage internal and external supplier registration questionnaires and approve or deny registrations." This directly supports the requirement to manage registrations.

Supplier Qualification Manager: "Members of this group manage supplier qualifications. They can create and manage qualification projects, invite suppliers to participate, monitor their progress, review their answers, and approve or disqualify them." This directly supports the requirement to manage qualifications and disqualifications.

Supplier Request Manager: "Members of this group manage internal supplier requests. They can approve or deny requests for new suppliers." This confirms it is a preceding step.

Preferred Supplier Manager: "Members of this group manage preferred supplier levels for suppliers..." This confirms it is a separate, subsequent status management function.
