“Radiografía” del estado de la reutilización de software en Colombia

Due to competitive markets, the software business wants faster, better, and cheaper solutions in a short amount of time. Software reuse emerges as a viable solution to these demands since it offers significant benefits, such as increased quality and efficiency and lower development costs and effort, as well as shorter commercialization times. This research aims to study and understand the state of the practice of software reuse in Colombia, to make comparisons with related works, and to offer an instrument for decision-making in companies that adopt these practices. To reach these objectives, three stages were proposed. In the first stage, the research questions were defined. In the second stage, a survey was developed, evaluated, and carried out to validate successful practices and adoption barriers in the context of the Colombian software industry. Finally, the results were analyzed and reported. This paper showed and evidenced the expectations, adoption barriers, and factors influencing the success of software reuse in Colombian industrial environments. In the same way, the experience from the development of this work serves as a roadmap for other regions that want to analyze the current state of reuse. Nevertheless, each organization needs to determine its capabilities and find the appropriate factors to be adopted to its context.Debido a los mercados competitivos, el negocio del software quiere soluciones más rápidas, mejores y más baratas en un período corto de tiempo. La reutilización de software surge como una solución viable para estas demandas, ya que ofrece importantes beneficios, como mayor calidad y eficiencia, menores costos y esfuerzos de desarrollo y menor tiempo de comercialización. Este artículo pretende analizar el estado de la práctica de la reutilización de software en Colombia, realizar comparaciones con trabajos relacionados y ofrecer con este resultado un instrumento para la toma de decisiones en empresas que adoptan estas prácticas. Para llevar a cabo los objetivos anteriores se plantearon tres etapas. En la primera etapa se definieron las preguntas de investigación. En la segunda etapa se desarrolló, evaluó y realizó una encuesta para validar prácticas exitosas y barreras de adopción en el contexto de la industria de software colombiana. Finalmente, los resultados fueron analizados y reportados. El estudio mostró y evidenció las expectativas, barreras de adopción y factores que influyen en el éxito de la reutilización de software en entornos industriales en Colombia. El presente estudio muestra el estado actual de las prácticas de reutilización en la industria de software en Colombia. Asimismo, la experiencia en el desarrollo de este trabajo sirve como hoja de ruta para otras regiones que quieran analizar el estado actual de la reutilización. Sin embargo, cada organización necesita determinar sus capacidades y encontrar los factores adecuados para adaptarlos a su contexto

BPMNt : a proposal for flexible process tailoring representation in BPMN /

Business Process Model and Notation (BPMN) is a de-facto standard for business process modeling, which focuses on the representation of the process behavior. However, it can also succeed in representing the behavior of software processes, since they are a type of business process. Although BPMN has been extensively used for modeling processes in different domains, its standard specification does not have any mechanism to support users in activities related to process adaptation (tailoring). Moreover, researches extending BPMN are based on complex consolidated models, which hamper the analysis and maintenance of individual variant process models and are not appropriate for application domains in which process variations are difficult to predict, such as in software development processes. Thus, our objective was to provide a BPMN-compliant extension and associated mechanisms for specifying flexible process tailoring on models produced with this language while ensuring the correctness of adapted process models and explicitly capturing change traces. We have focused our research on the domains of Software Process Engineering (SPE) and Business Process Management (BPM). At last, we evaluated the applicability of the proposal for representing realistic tailoring scenarios in both domains.BPMN (Business Process Model and Notation) é um padrão para modelagem de processos de negócio, que tem seu foco na representação do comportamento de processos. No entanto, ele pode também ser usado para representar o comportamento de processos de software, já que eles são um tipo de processo de negócio. Embora BPMN tem sido extensivamente usado para modelar processos em diferentes domínios, sua especificação padrão não possui nenhum mecanismo para apoiar usuários em atividades relacionadas à adaptação de processos. Pesquisas que estendem o padrão são baseadas em modelos complexos, que dificultam a análise e manutenção de modelos variantes, e não são apropriadas para domínios de aplicação onde variações de processo são difíceis de predizer, como em processos de desenvolvimento de software. Assim, nosso objetivo foi fornecer uma extensão para BPMN, chamada BPMNt, e mecanismos de suporte para especificar, de modo flexível, adaptações em processos modelados com esta linguagem. BPMNt deve também garantir a corretude de modelos adaptados e explicitamente capturar rastros de mudanças realizadas. Essa pesquisa teve como foco os domínios de Engenharia de Processos de Software e Gerenciamento de Processos de Negócio. Por fim, nós avaliamos a aplicabilidade da proposta para representar cenários de adaptação reais em ambos os domínios
