 Generally speaking, I mean, you use the solicitation to your advantage because the requirements are clearly spelled out in solicitation, and then the proposal that you provide is obviously in response to that solicitation, and then you have the final contract. Anytime there's a deviation in the government's direction or instruction to you, so the instruction or direction deviates from what's written in that contract, which stemmed from the solicitation or proposal, then that's what constitutes the ability to ask for, you know, one, to say it's a change, and then two, to ask for some type of remediation as a result of it.
