What changes to an OP would be considered significant enough to require a re-application?
Changes to an OP may require a document review / systems audit and subsequent on-site verification audit, but not a re-application. Once OA’s have applied for accreditation, they need not re-apply unless their accreditation has been revoked or they are applying for a new system. That being said, the OA must notify the CGSB of any changes to their OP that they believe might be significant enough to risk non-conformity with the Standard.
