Inlessthanadecadeofexistence, theWebhasreachedatrulystaggeringstage, demonstratedbythescope, thereach, andthesizeofWeb-basedapplications andactivities. Concentratinginitiallyoninformationdissemination, thescopeof theapplicationsisnowlimitedonlybyourimagination. Thereachisconstantly expandingandsoarethenumberandsizeoftheapplications, alongwiththe underlyingcomplexity, rangeofpurposes, andthetimeneededtodevelopand maintainthem. Atthesametime, thedevelopmentandmaintenanceprocesses ofWebapplicationshavenotprogressedatasu?cientlyrapidpacetomeetthese challengesanddemands. Consequently, thelikelihoodisthatWebapplication developmentwillgetintoacrisisanditisnothardtoimaginethatthiswould dwarfthe softwarecrisis identi?edlongagointhe1960s. WebEngineeringaimstoavertthispotentialcrisisbygeneratingaproactive approachtothesuccessfuldevelopmentofWeb-basedsystemsandapplications.

Themainpurposebehindtheseworkshopshasbeentoshareandpoolthe collectiveexperienceofpeople, bothacademicsandpractitioners, whoare- tivelyworkingonWeb-basedsystems. Theworkshopshavegenerallyconsisted ofkeynoteaddresses, peer-reviewedcontributedpapers, andsessionsofopen discussions. About This Book Inthisvolume, weprovideaconsolidatedviewofrecentwork, highlightingdev- opmentsandadvancesintheareaofWebEngineering. Thisselectionofpapers drawsmainlyfromthelastthreeworkshops, heldinconjunctionwithICSE1999, WWW9, andICSE2000. Wealsopresentalistofadditional, usefulresourceson WebEngineeringsuchasbooks, specialissues, articles, andWebsites. Ouraim istoprovideabookthatwillbeaconvenientandusefulreferencetoallthe researchers, practitioners, andstudentsinterestedinWebapplicationdevel- ment. WebEngineeringtakesitsinspirationfromSoftwareEngineering. Atthe sametime, itisalsoanexplicitacknowledgementofthemulti-dimensionalnature ofWebapplications, encompassingtechnicalcomputing, informationstruct- ing, navigationandmanagement, networkperformanceandsecurity, legaland socialissues, graphicdesign, multiplicityofuserpro?les, andthevariedope- tionalenvironments. Accordingly, thepapersinthisvolumecoverperspectives onWebEngineering, navigationandadaptivity, designaspects, acceptancec- teriaforWeb-basedsystems, developmentandmanagementofWebsitesand Web-basedapplications, Webmetrics, andcasestudies. Forconvenience, thepapersareorganizedin?vesections:1)Introduction andPerspectives,2)ManagingInformationontheWeb,3)Web-BasedSystems Development,4)DesignforPerformance, WebMetrics, andTesting, and5) WebMaintenanceandReuse. Intheirownways, allthepapersareforwa- looking, tryingtoanticipateproblems, creatingtools, experimentinginnovel ways, wideningtheareasofapplications, andre-examiningparadigms. Inother words, thepapersrepresentasharedattitudeofbeinginclusiveratherthan focusingnarrowly. WebEngineeringisaforwardlookingandcollaborativediscipline.
