Abordagens de reuso de requisitos: estudo de caso com sistemas de software para gestão eletrônica de documentos

Abstract

The presente work presentes a study case carried out in an electronic documents managemet software, Birô de Digitalização and Digitaldoc – Anix Sistemas Ltda company products. The proposal is to apply requirements reuse at these products. The objetive is to help/speed up the elicitation and requirements specification phases, keeping the software quality and reducing the development and final product cost, show that unconsciously requeriments reuse are made in many cases.That surrounding context settings advantages, and applications are described at requeriment reuse software systems. Two requeriment reuse approaches were applied: software systems analogy and requeriments reuse. To demonstrate the application of the first approach it was made the comparison between activities (registration and scanning) performed by the system through the activity diagram. As a result of the comparison reuse was partially proven, even though the registration and scanning activities are identical, Digitaldoc has other features implemented. The second approach was based at system functional requirements, Birô de Digitalização and Digitaldoc, this is, the direct comparison of these requirements. As a result, requeriments reuse was proven, even though the functional requirements from both systems are identical. It was perceived similarity at some non functionl requirements. To perform the study case it was necessary to develop class diagrams and activity diagrams from the cited softwares, this improved the understanding and demonstration of the approach reuse aplication.
