Also known as: approved signatory, report signatory, key technical personnel.
Why it exists
Accreditation to ISO/IEC 17020 or 17025 is granted to the company, but the competence to release results is personal. Naming signatories makes clear who takes technical responsibility for each report and lets the accreditation body interview and assess those people.
Signatories in AMPS
AMPS records who created, reported and closed each job through its history feature, and reports can be signed electronically in AMPS, so the signatory trail for a job is available without digging through email.
