The objective of this work was to define guidelines for Use Case Model (Use Case Diagram and Specification) construction. The use of use cases and UML notation for requirements modeling is a widely used option, don' t matter the development paradigm. However, neither guidelines for Use Case construction are provided by UML, neither there are works in the literature that provide a more systematic support for this activity. Hence, this activity is very dependent on the designer experience and subjectivity, leading to different models for the same system. The proposed techniques, named GUCCRA Guidelines for Use Case Construction and Requirement Analysis, are composed of two readings, AGRT Actor Goal Reading Technique and UCRT Use Case Reading Technique. The definition of these techniques was based on two other reading techniques: PBR-User, used for requirements Document inspection and ER1, of OORTs/ProDeS family, used to validate Use Case Models in relation to the Requirement Documents that were the basis for the model construction. Aiming at evaluating GUCCRA two empirical studies were carried out: the first compared the proposed techniques with an Ad-Hoc approach by constructing Use Case Models related with some Requirement Documents. The second study compared the defects related during the models construction with the defects of PBR-User application in the same documents. From the first study, the results provide evidences that the activity became more systematic with the use of the techniques and that the models became more standardized. From the second study the results showed that the majority of defects found were common to both techniques. Moreover, a study has been prepared to show the positive influence of the systematic standardization of Use Case Models in the application of the Use Case Point metric.
