If I requirement was previously competed and no further competition is required to award follow-on work, is this new follow-on work now considered non-competitive? Or is it an extension of the prior competition?

Example A: FAR-based follow-on production contract derived from a successful (and competed) prototype OTA. 

Example B: FAR-based Phase III SBIR for production following a prior competitive Phase I SBIR. 

Identify the actions as either competitive or non-competitive will have a major impact on approval levels. 

Follow-on work may qualify as an exception to competition. See FAR 6.302-1 (a)(2)(ii)

Hopefully, the original acquisition plan contemplated and covered the follow-on contract.

And, hopefully, the original competitive solicitation and the resultant contract explained the process for awarding the follow-on contract.
