A question that often comes up is: How much help can I provide to the manufacturer as a verifier? This brings us to the integrity in the verification process remaining impartial.
To maintain the integrity of the verification process, organizations that have been approved as HPD TPVs may prepare HPDs, and can also be HPD Approved Preparers. However, organizations cannot verify the same HPD that they have in any way been involved in preparing.
HPDC does not specifically prohibit working in dual roles for the same manufacturer on separate HPDs, especially if they are from completely different product lines. Use your best professional judgment, and check with HPDC for clarification.
