Use of Checklist for Requirements Revalidation in Legacy Software: Case Study RETEC

The technologies employed in computer systems have evolved quickly in recent years. Not always the institutions manage to stay updated to new technologies and often they keep using obsolete technologies. The migration of those systems to new platforms come up against many difficulties with regard to restructuring and migration to modern platforms, understanding what the system does, or should to do. Based on this principle, the problem in hand is to conduct activities related to an electronic journal, which currently are performed out manually. In this sense, this study aims to adapt and include RETEC to the national magazine publishing model, called SEER, as well as examine if the features of this platform meets the needs of publishers. The methodology adopted the following steps: requirements elicitation, implementation stage and system validation. During this study, it was also developed a requirement validation methodology by conducting a checklist test. The method developed allowed specifications, in the requirements document, to be verified and validated in an objective, efficient and standardized way. Therefore, the methodology developed and used in this study has characteristics that make it feasible to be applied during inspection and validation of requirements for a good quality software with a low number of errors, independently of analyzed tool.
