Trust, But Verify:
The GPC Verification Process
The GPC Group has established a verification process for all results
published in the GPC News. The process, used by all GPC
project groups, is designed to sanction all results published
in the on-line and quarterly hardcopy publications.
The following steps constitute the reviewing procedures:
- On the day indicated by the approved GPC News publication
schedule, results are placed in an "incoming" directory
of the GPC's private Web site.
- The following day, the GPC administrator assigns reviewers
among those vendors that have submitted new results. No vendor
representative is allowed to review his or her own numbers. In
addition to the reviewing assignments, all members have access
to new results and can review them if they wish.
- A scheduled period of time -- usually one week -- is allowed
for review. Each reviewer is responsible for reviewing the submission
and deciding whether to accept it, accept it with comment, or
not accept it with comment. Comments on submissions are not limited
to review teams; anyone within a project group may review materials
and direct comments or questions to the vendor submitting the
results. Any project group member can request that the submitting
vendor recreate the results in his or her presence.
- Once reviews have been completed, there is a period of appeal
for any vendor whose submission has not been accepted. The entire
project group is permitted to comment during this period. The
appeal period culminates in a call for a vote on whether to accept
or reject the appeal. If the appeal is turned down, the vendor
representative has a choice of changing his or her submission
to satisfy requirements, or to withdraw the results.
Members of any project group may run their own performance tests
and publicize results at any time. The numbers are not officially
sanctioned, however, until they go through the official verification
process prior to publication in the GPC News.
The verification process established by the GPC Group is based
on the premise of "trust, but verify." Under this system,
vendor representatives are trusted to produce legitimate results;
these results, however, undergo a verification process that leaves
little doubt as to the authenticity of numbers published in the
