Which of the following techniques is based on a set of criteria that has been acquired in a specific knowledge area or product area?

Expert judgment is formally defined as input provided by individuals or groups with specialized training, knowledge, or experience in a particular knowledge area or product domain, making it the direct match for a technique based on criteria acquired in a specific field. It is used across multiple process groups in project management precisely because domain-specific expertise provides the foundational criteria that other analytical techniques cannot supply. No other listed technique is defined by the acquisition of knowledge in a specific domain as its core characteristic.

PERT is a scheduling estimation technique that uses optimistic, pessimistic, and most likely time estimates to calculate expected duration, not a technique grounded in domain-specific acquired criteria.

Function Point Analysis is a software sizing method that measures application functionality from a user perspective based on requirements, not a general technique derived from expertise in a knowledge area.

The Delphi technique is a structured group consensus method using anonymous questionnaires and iterative rounds to converge expert opinions, making it a facilitation process rather than one based on criteria acquired in a specific domain.
