	abstract = {To get to grips with information systemsportfolio development, strategic decisions tend towardservice orientation and cloud deployment. Functionalityshould be presented as services that can be consumedfrom secure clouds in a range of contexts, and serviceorientedarchitectures should enable one to build andrebuild systems portfolios readily and rapidly. However,there is little practical guidance on how to organize andcoordinate the multiple lines of work that developing, ormodernizing to, a service-oriented portfolio entails. Weoutline a method framework that uses the structure ofa service-oriented taxonomy of capabilities to organizerequirements and development in terms of elaborationand refinement of requirements. The method compilesseveral best practices, and supports independent, butintegral, lines of work that can be organized in smallscaleprojects. We illustrate the framework on threecases that involve computer- and simulation-assistedbusiness processes. We conclude that service-orientedcapability taxonomies can be used to structure and disciplinerequirements handling at all levels; from enterprisestrategy to technical systems.We suggest that ourframework supports the development of capabilities andservices that are persistent in the service-oriented senserelative to each other and to implementation. We suggestfurther that the framework supports collaborativework by facilitating shared conceptions across lines ofwork. We emphasize that empirical studies should beconducted to evaluate and refine the framework.},
