Evaluating a technique for requirements extraction from business process diagrams through empirical studies

In the area of requirements engineering there are elicitation techniques that are based on business context to identify the software requirements. However, these techniques do not commonly use business processes models as a source of information relevant to the elicitation of requirements. Such techniques extract use cases from business processes models. However, before modeling use cases, it is important to produce a document with functional and non-functional requirements and business rules. Therefore, this work proposes a new technique to aid extracting the requirements from business process diagrams: the REMO (Requirements Elicitation oriented by business process MOdeling) technique. This paper shows that, through the use of empirical studies, it was possible to obtain results that contributed to the evolution of the REMO technique. Additionally, the paper describes the qualitative analysis of the second empirical study, which used the procedures of two different methods: the Technology Acceptance Model (TAM) and Grounded Theory.
