During the last two decades we have seen tremendous developments within software engineeringresearchandpractice.Theeverincreasingcomplexityofsoftwaresystems andtherevolutionarydevelopmentintheInternethaveledtomanyinterestingchallenges andopportunitiesfornewdevelopmentsinSoftwareProcessTechnology. Started in 1990, the primary goal of the European Workshops on Software P- cessTechnology is to achieve better understanding of the state-of-the-art on all issues related to software process technology, including (but not limited to): process mo- linglanguages,computer-supportedprocessdescription,analysis,reuse,re?nementand enactment,processmonitoring,measurement,management,improvementandevolution, process enactment engines, tools, and environments. Besides the technical viewpoint, the workshops have also taken into account human and social dimensions in software processenactment. The9thEuropeanWorkshoponSoftwareProcessTechnology(EWSPT-9)provided aninternationalforumforresearchersandpractitionersfromacademiaandindustryto discussawiderangeoftopicsintheareaofsoftwareprocesstechnology,andtojointly formulateanagendaforfutureresearchinthis?eld.

I would like to thank the members of the Program Committee (Jean-Claude D- niame, Jacky Estublier, Carlo Ghezzi, Carlo Montangero, Leon Osterweil, Dewayne Perry, and Brian Warboys) for providing timely and signi?cant reviews, and for their substantialeffortinmakingEWSPT-9asuccessfulworkshop. This year the workshop was held in conjunction with the joint European Software EngineeringConferenceandACMSIGSOFTSymposiumontheFoundationsofSo- ware Engineering.
