An Empirical Evaluation of Requirements Elicitation from Business Models through REMO Technique

The Requirements Elicitation oriented by business process MOdeling (REMO) technique presents a set of heuristics to support the elicitation of requirements based on business process models. Although empirically validated only in controlled environments, the literature does not report evidence regarding the applicability of the technique in real scenarios. In this context, this paper presents an empirical evaluation applied in an industrial settings, using a multimethod approach, where a quantitative analysis measured the applicability of the technique and a qualitative analysis the utility and ease of use according to requirements analysts. As for the results, the quantitative analysis made it clear that the REMO technique can bring real benefit in the context of the study, identifying a higher number of funcional requirements than the conventional approach (without the support of the REMO technique). This benefit is reached without overcomplicating the task of eliciting requirements.
