Software Engineering Rationale (SER) can play several roles in supporting system evaluation. One is to support the evaluation of decision alternatives by providing the means to capture the arguments for and against each alternative. The rationale can be used to automatically calculate support for alternatives and present it to the developer to assist them in making, or revising, their decisions. Rationale also supports usability evaluation by providing a process for analyzing use scenarios via Scenario-Claims Analysis (SCA) (Carroll and Rosson 1992; Carroll 2002). In this chapter, we discuss a number of approaches for using rationale to evaluate the alternatives to assist with decision-making and also how SCA supports usability evaluation.
