Differentiation Between Origination and Underwriting In Lender Vocabulary

Hey all, pretty simple question here, that frankly I'm embarrassed to be asking. But anyways, I notice at a lot of boutique lenders some shops tend to differentiate between their Originations team versus their Underwriting team. From my understanding originations is more about sourcing and being in the market anticipating what types of capital solutions you can provide to capital seekers. My question then is what exactly does a designated "Underwriting Analyst" do? Strictly modeling and diligence? Is there a reason why debt groups don't let their modeling analysts face the world? Please advise.
