8.4.2 Audit Procedure
To
ensure against conflicts of interest, all audits should be conducted by
individuals who are independent of the organizations responsible for the
monitoring and/or using the data. This is especially important as the audit
will be essential in any legal claims related to data validity. The audit
should begin with a briefing stating the goals of the audit and the
procedures to be employed - in addition, if any assistance is needed (e.g.,
in removing a wind vane from a tower) this would be the time to
arrange such with the site technicians. An exit interview should be
conducted when the audit is finished; management from the organizations
involved should be present at both the initial briefing and the exit
interview.
