Evolution vs. innovation in requirements for services

In the services computing era, technologies are developed to serve for the purpose of putting existing information services assets into new use, creating new value for both the providers and customers. To this end, the range of requirements can be satisfied by the existing services has to be understood better. At the same time, different ways to compose, decompose, configure and reconfigure services on demand has to be explored, i.e., we should know how to evolve current service specifications and designs to satisfy emerging needs. If evolution is not possible, people either set off for innovative designs or settle with what is available in the services pool. This paper states our general observations on this issue and reports our work on a service evolution and innovation framework.
