Workshop Overview


Many of today’s large-scale software projects in the area of distributed systems and especially enterprise IT adopt service-oriented software architecture and technologies. For these projects, availability of sound software engineering principles, methodology and tool support is mission-critical. However, traditional software engineering approaches are not fully appropriate for the development of service-oriented applications. The limitations of traditional methods in the context of service-oriented computing have led to the emergence of software service engineering (SSE) as a new specialist discipline, but research in this area is still immature and many open issues remain. There is an urgent need for research community and industry practitioners to develop comprehensive engineering principles, methodologies and tool support for the entire software development lifecycle (SDLC) of service-oriented applications. The WESOA 2009 workshop is the fifth in a series of workshops that focus on the specific aspects of SSE.

WESOA highlights key challenges of SSE that arise from specific characteristics of service-oriented applications that are often process-driven, loosely coupled, composed from autonomous services of complex IT landscapes and closely related to diverse socio-economic contexts. Service-oriented computing (SOC) enables the materialization of organizational processes as flexible compositions of autonomous service components. Stakeholders, domain experts, software architects and engineers instrument service-oriented software architectures (SOA) to drive constant organisational change by means of agile reengineering of software services, system landscapes and applications. In particular, service-oriented applications need to provide multiple, flexible and sometimes situational interaction channels within and beyond organizational structures and processes. Engineering of such software systems requires continuous, collaborative and cross-disciplinary development processes, methodologies and tools that synchronize multiple SDLCs of various SOA artefacts with organizational innovation processes.

Our aim is to facilitate exchange and evolution of ideas on SSE topics across multiple disciplines and to encourage participation of researchers and practitioners from academia and industry. In particular, collaboration will be fostered by means of a highly interactive and fast-paced workshop format.



WESOA Series

WESOA'09 continues a successful series of former ICSOC workshops. During the past four editions, WESOA has demonstrated its relevance by constant high numbers of contributions and participants. Its impact is documented by consistent output of high-quality papers.
