Constructing Use Case Model by Using a Systematic Approach: Description of a Study

This paper presents the results of a feasability study that was carried out to evaluate the construction of Use Case Models by comparing the models with groups that used the GUCCRA techniques and groups that did not use them, that is, they only used their experience (Ad-Hoc). GUCCRA – Guidelines for Use Case Construction and Requirements document Analysis – is a set of two reading techniques that helps the elaboration of Use Case Models and, simultaneously, provides an opportunity to identify defects in the Requirements Document. The results of the study showed that applying a systematic and procedural technique to construct Use Case Models, a larger standardization may be reached and the construction process becomes more independent from the designer’s subjectivity and experience.
