I really believe that the evaluators should be part of the department. This is a management tool. It is much like internal audit.
I know we've had discussions with the committee about where internal audit should report. We've always taken the position that internal audit evaluators should be reporting to the deputy head rather than to some external organization—say, the Treasury Board Secretariat.
This is really to be used by management to improve programs. It is not an external audit function or an external evaluation function. The responsibility really should come back to the deputy head to ensure that someone performing the function is well qualified and doing appropriate work and that the results are acted upon.
