 Almost all informal logics understand a good (strong) argument to be an argument with “acceptable” premises and a “valid” inference — i.e. a conclusion that follows from them. Hansen 2012 has argued that informal logic should follow classical logic, and not concern itself with the assessment of premise acceptability, but its engagement with real life arguments (and the desire to evaluate them in a fulsome way) has produced a field that includes this within argument evaluation. In this and in other regards, systems of informal logic adopt many different approaches to argument assessment.
