Aplicação de um processo de V&V em uma empresa de desenvolvimento de software ágil: um estudo de caso

Abstract

In a competitive scenario, in which companies must respond quickly and efficiently to changes proposed by the market, it has become impracticable, from an economic and temporal point of view, to raise all the requirements of a system. In view of this, conventional processes, which prioritize procedures and roles are well defined during the development cycle, tend to fail, as most of them tend to take a long time, going against the new global model, which prioritizes quick deliveries. Based on this, the need arose to implement “lightweight” processes that were capable of adapting to the changes imposed during development. Soon, agile methods emerged as a way to reconcile software development, along with the flexibility of requirements, always prioritizing product deliveries in a fast and versioned way. In the same way that the development process had to be modeled to meet market demands, the Verification and Validation (V&V) methodologies also had to adapt to meet the principles proposed by the Agile Methodologies. As an example, we can mention the test in XP (Extreme Programming), which proposes that the tests be carried out even before starting the coding process, thus reducing possible errors that may occur. Therefore, if applied correctly, the application of these processes enables faster and higher quality deliveries, bringing confidence to the team and promoting customer satisfaction. In this context, a case study was carried out in a Software Company, whose main objective was to identify the main difficulties of the development process and to implement verification and validation techniques, investigated in the literature, in the different stages of development.
