To get to grips with information systems
portfolio development, strategic decisions tend toward
service orientation and cloud deployment. Functionality
should be presented as services that can be consumed
from secure clouds in a range of contexts, and serviceoriented
architectures should enable one to build and
rebuild systems portfolios readily and rapidly. However,
there is little practical guidance on how to organize and
coordinate the multiple lines of work that developing, or
modernizing to, a service-oriented portfolio entails. We
outline a method framework that uses the structure of
a service-oriented taxonomy of capabilities to organize
requirements and development in terms of elaboration
and refinement of requirements. The method compiles
several best practices, and supports independent, but
integral, lines of work that can be organized in smallscale
projects. We illustrate the framework on three
cases that involve computer- and simulation-assisted
business processes. We conclude that service-oriented
capability taxonomies can be used to structure and discipline
requirements handling at all levels; from enterprise
strategy to technical systems.We suggest that our
framework supports the development of capabilities and
services that are persistent in the service-oriented sense
relative to each other and to implementation. We suggest
further that the framework supports collaborative
work by facilitating shared conceptions across lines of
work. We emphasize that empirical studies should be
conducted to evaluate and refine the framework.
