Task Orders and Change Orders may have similar administration rules, but the basis for these rules is a little different in that a task order is ALWAYS a procurement activity that is subject to review during a CPSR. In NO CASE should a task order award be withheld from a CPSR data call (unless of course there's another basis for exemption - IWO, etc.). So while a Change Order is only reviewable during a CPSR if it amounts to a new procurement activity, a Task Order is always procurement activity.
