Software configuration management

Thedisciplineofsoftwarecon?gurationmanagement(SCM)providesoneofthe bestsuccessstoriesinthe?eldofsoftwareengineering. Withtheavailabilityof over100commercialSCMsystemsthattogetherformabillion-dollarmark- place,andtheexplicitrecognitionofSCMbysuchstandardsastheCMMand ISO-9000,thedisciplinehasestablisheditselfasoneoftheessentialcornerstones ofsoftwareengineering. While SCM is a well-established discipline, innovative software engine- ing approaches constitute new challenges that require support in the form of new or improvedtools, techniques, and processes. These challengesemerge in component-baseddevelopment,distributedsystems,dynamicallyboundand- con?gured systems, embedded systems, software architecture, Web-based s- tems,XML,engineering/productdatamanagement,systemengineering,process support,concurrentandcooperativeengineering,etc.^ Since the ?rst SCM workshop was held in 1988, the workshop series has providedarecurringforumforresearchersandpractitionerstopresenttechnical contributions,toexchangeanddiscussideas,andtoestablishcontactsforfurther cooperation. Thecurrentvolumecontainspapersfromtwoworkshopswhichwere bothco-locatedwiththeInternationalConferenceonSoftwareEngineering,but di?eredintheirformatsandgoals. SCM-10washeldasanICSEworkshopatToronto,CanadainMay2001. It wasdeliberatelydecidedtohaveaninformalworkshopinordertoopenaforum fordiscussingnewpractices,newchallenges,andnewboundariesforSCM. This wasachievedbyablendofinvitedtalks,talksonselectedpositionpapers,and lively discussions. Originally, informal proceedings were produced which were deliveredtotheworkshopparticipants. Lateron,5outof22submissionswere selectedforpublicationinthis jointvolume. Allauthorswereaskedtoextend theircontributionstofullpapersandtorevisethemthoroughly.^ WhiletheSCM-10experimentprovedverysuccessful,theSCMcommunity feltthatitshouldgoforaformalworkshoponceagain. Infact,thiswouldopen uptheopportunitytodocumentcurrentresearchandfertilizethedevelopment ofthisdiscipline. Asaconsequence,thefollow-upworkshopSCM-11washeld as a co-located event with ICSE at Portland, Oregon in May 2003.
