Service orientation is a new software engineering paradigm that introduces opportunities as well as challenges. Although existing processes and practices can be reused for service oriented development, novel techniques are required to address unique SOA requirements. Work in this area is quite active and only recently is producing some initial results. The aim of this paper is to present a state-of-the-art survey on current service oriented development approaches. The characteristics that distinguish between these approaches are discussed and a number of actual methodologies that have emerged or are still emerging are de- scribed and compared.
