Metodologias híbridas no desenvolvimento de sistemas embebidos

Metodologias híbridas no desenvolvimento de sistemas embebidos

Abstract

Nos últimos 20 anos, as metodologias ágeis têm vindo a afirmar-se como uma referência metodológica nos projetos de desenvolvimento de software. Esta realidade alicia muitos gestores a identificarem a necessidade de implementar esta abordagem no desenvolvimento de sistemas embebidos. Todavia, esta tarefa torna-se complexa devido à natureza deste tipo de projetos. Por esta razão têm surgidos propostas de utilização de metodologias híbridas, que são uma abordagem de desenvolvimento que combina práticas ágeis e tradicionais. No entanto, a sua utilização atual tem sido relatada como pouco estruturada, não havendo um enquadramento claro dos benefícios para o desenvolvimento destes sistemas específicos. Assim, este estudo pretende aprofundar o conhecimento atual sobre as práticas correntes no âmbito da utilização das metodologias, explorando e mapeando-as, em particular no que toca às metodologias híbridas. Foram realizadas quatro entrevistas semi-estruturadas para ganhar um maior entendimento sobre o contexto que leva à utilização de metodologias híbridas no desenvolvimento de sistemas embebidos. Posteriormente, foi aplicado um questionário a 132 profissionais da área dos quais se 68 forneceram respostas válidas. A análise dos resultados revelou que as metodologias mais utilizadas em Portugal não diferem das anteriormente reportadas na literatura. Porém, foi possível estabelecer uma dependência estatística entre as metodologias Scrum e Waterfall, confirmando a existência e utilização da metodologia híbrida Water-Scrum-Fall

Across the last 20 years, agile methodologies have substantially increased their influence on software and systems development. This reality encourages many managers to identify the need to implement this approach in embedded systems development projects. However, this task becomes very complex due to the nature of such development projects. For this reason, efforts have been made to use hybrid methodologies, which are a development approach that combines agile and traditional practices. Nevertheless, this use has been reported as unstructured and without a clear framework for the benefits to the development of these specific systems. Thus, this study intends to expand the current knowledge about current practices in the use of methodologies, exploring and mapping them, namely concerning hybrid methodologies. Four semi-structured interviews were conducted to acquire a deeper understanding of the reasons that lead to the use of hybrid methodologies in the development of embedded systems. Subsequently, a questionnaire was applied to 132 professionals in the area of embedded system development, from which 68 provided valid answers were collected. The analysis of the results revealed that the most used methodologies in Portugal do not differ from those previously reported in the literature. Still, it was possible to establish a statistical dependence between Scrum and Waterfall methodologies, confirming the existence and application of the Water-Scrum-Fall hybrid methodology.
