I see that a subcontracting plan is not required under NITAAC. Could you please explain why this is so?

NITAAC subcontracting plans are established on the master contract (i.e. CIO-SP3 or CIO-SP3 Small Business) level. These plans flow down to the individual task order level and are not required to complete your order.
