5. PESOS 2011 5 Motivation  Service-oriented systems represent a new class of software system Software is used and integrated as external, loosely- coupled services rather than being physically integrated and owned permanently  However, service orientation poses challenges to more traditional approaches to software development Lack of homogeneity of its basic components Changing business and deployment environments

6. PESOS 2011 6 Workshop Goals  Provide a forum for presenting and discussing possibilities of synergy between Software Engineering (SE) technologies and Service-Oriented Computing (SOC) that are beneficial to both fields  Bring together researchers and practitioners working in the area of engineering service-oriented systems to discuss Research challenges Recent developments Novel applications Methods, techniques and tools Theoretical foundations Empirical studies Experiences Lessons learned

7. PESOS 2011 7 Workshop History SDSOA 2007 Organizers from Software Engineering Institute, IBM Canada, European Software Institute and the University of Waterloo presentation of results from a SOA Research Agenda IRAD project SDSOA 2008 Research agenda was used as the framework for the workshop Updates were presented PESOS 2009 Organized by a group of EU researchers Focus on how to achieve evolution and adaptation in a secure and dependable way Invited presentation of the SOA research agenda showed huge potential for synergy between both communities Successful joint proposal PESOS 2010 IW-SOSE 2006 IW-SOSE 2007 Focus on the engineering of service- oriented software systems Focus on the engineering and use of service- oriented software systems Here we are again! PESOS 2011
