Abstract. Whilst Web services can be composed by technical developers using a language such as BPEL, there is no easy way for non-technical end users to take advantage of these services. The advent of Web 2.0 and mashups has brought about the notion that content from different sources can be brought together by the user themselves to create a new service. Inspired by such ideas, we propose a lightweight end-user service composition paradigm, namely; Stones, Stories and StoryBoard. A Stone is a representation of a commonly performed task or operation that can be used to construct a Story. StoryBoard provides an intuitive drag-anddrop style user environment in which the Stories are created, validated and run. We demonstrate the concept through an implementation of a case study on bill management.
