Thanks everyone. No, the attorney did not provide rationale. Everything I'm getting refers to 16.505 (B ), etc (which states SHOULD not SHALL) and "best practices". We intend to award the majority of our task orders immediately after the IDIQs are awarded (hence my question on the difference between the task order PP and the IDIQ PP). I agree that if we award some down the road (after we have performance data on the initial orders), then it might make sense.
Just as an FYI - we are doing a very intensive PP eval at the IDIQ level (questionaries' sent in by the offerors, Gov't pulling PPIRS, and rating based on relevancy and recency).
We'll see how it goes pushing back on the attorney!
