GUCCRA: Contribuindo para a Identificação de Defeitos em Documentos de Requisitos Durante a Construção de Modelos de Casos de Uso

This paper presents the results of case studies that were carried out aiming at evaluating the defects identified by GUCCRA application and PBRUser application. GUCCRA – Guidelines for Use Case Construction and Requirements document Analysis – is a set of two reading techniques that helps the elaboration of Use Case Model and, simultaneously, identifies defects in the Requirements Document. The results of the case studies shown that the most part of defects identified by PBR-User also were identified by GUCCRA techniques. Besides, GUCCRA techniques identified defects that PBR-User did not. This characteristic must be due the GUCCRA techniques application, allowing the identification of defects during a systematic and procedural approach to construct Use Case Model.
