PESOS 2011

1. 3rd International Workshop on Principles for Engineering Service-Oriented Systems PESOS 2011 Organizers Manuel Carro Dimka Karastoyanova Grace A. Lewis Anna Liu ICSE 2011 Hawaii, USA May 23-24, 2011

2. Grace A. Lewis CMU Software Engineering Institute, USA Welcome

3. Agenda Day 1

4. Agenda Day 2

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

8. Workshop Logistics • Two keynotes • One invited talk • Three paper sessions • Introduction • Papers • Discussion • One panel • We expect highly interactive sessions • We will be taking notes throughout the workshop and present a summary at the end of each day

9. Informal Dinner • Tropics Bar & Grill — Ali’I Tower, by the beach • Reservation at 7PM under Grace Lewis • Currently for 20 people • Two caveats • Bill will include 18% gratuity • They will not do separate checks for a group of that size • If interested, please mark it on the sign-in sheet

10. Introductions Briefly state your name, organization, and areas of interest related to service orientation

16. Facilitator: Manuel Carro Universidad Politécnica de Madrid (UPM) and IMDEA Software, Spain Panel: Proposed Areas of Research in Order to Improve the State of the Practice in Service-Oriented Systems Engineering

17. Panelists Marin Litoiu (York University, Canada) Elisabetta Di Nitto (Politecnico di Milano, Italy) Andrea Zisman (City University London, UK) Liam O'Brien (CSIRO, Australia)

18. Question In your opinion, what areas should we be working on in order to improve the state of the practice in service-oriented systems engineering?

19. Grace A. Lewis CMU Software Engineering Institute, USA Welcome to Day 2

20. Agenda Day 2

21. Principles of Engineering Service-Oriented Systems (So Far …) • Think globally • Bound instead of control behavior • Plan for diversity • Increase flexibility • Reduce complexity • Enable agility
