I would like to remind the group that many types of evaluation exist;
effectiveness, cost effectiveness, and cost-benefit are some examples.
More important, most evaluations gauge how well you meet the demands of
competing groups in relation to your goals and objectives.  I suggest that
any efforts at evaluation start with a definition/clarification of those
goals and objectives.  Otherwise, an excessive number of
issues/problems may be encountered/created for which resolution may
become near impossible;  in other words, planning and focus are the keys
to a successful (pre)evaluation.

My two cents.
