Which of the following is NOT a role typically identified in the purchasing process?

In the purchasing process, roles are defined to clarify who participates in various stages of decision-making and influence. Each identified role has a specific function:

• The decider is the person who ultimately has the authority to make the purchasing decision.

• The user is the individual who will utilize the product or service, providing insights into its functionality and usefulness.

• The financier is involved in budgetary considerations, ensuring that funding is available for the purchase.

The term "validator" is not a standard role associated with the purchasing process. While there may be individuals who validate the choice made, such as by checking compliance with regulations or confirming alignment with organizational needs, this role is not typically categorized in standard purchasing terminology. Therefore, "validator" is the correct choice as the option that is not traditionally recognized in the purchasing process framework.
