Cost estimation in software engineering projects with web components development

La correcta prediccion de costes es crucial para el exito de un proyecto de ingenieria del software, dado que una estimacion incorrecta puede derivar en el fracaso del mismo. Existen multitud de modelos propuestos para abordar esta parte de la gestion del proyecto, algunos orientados especificamente para proyectos de componente Web. Este trabajo trata de analizar si esta gestion especifica de proyectos Web esta justificada, examinando el comportamiento diferencial de los costes entre proyectos de desarrollo software Web y no Web. El analisis se centra en dos aspectos del calculo de costes: las deseconomias de escala que se dan en este tipo de proyectos, y el impacto que conllevan algunas caracteristicas de estos proyectos que son frecuentemente utilizados como cost drivers. Tras una revision de las caracteristicas principales de los desarrollos de proyectos Web, se enuncian dos hipotesis: (a) en estos proyectos las deseconomias de escala son mayores y (b) el efecto del incremento de coste que provocan los cost drivers de coste es menor para los proyectos Web. Se contrastaron estas hipotesis utilizando una base de datos con datos de proyectos reales. Los resultados sugieren que ambas hipotesis se cumplen, lo que justificaria el desarrollo y uso de modelos especificos para este tipo de proyectos.
