Historically,aworkshopseriesfocusedspecificallyon empir-ical methods in RE was created in 2011 in the form of the InternationalWorkshoponEmpiricalRequirementsEngineering (EmpiRE),and onearticle fromits2012editionis publishedin this special issue.The EmpiRE workshop series buildsupon an earlier workshop series onComparative Evaluation in Require-ments Engineering (CERE) (2003–2007), and which aimed at setting up systematic empirical evaluation practices that serve thepurposeofcomparingREmethods,processesand
technolo-gies (Gervasi et al., 2004). The workshop triggered a number
of important conversations on pragmatic topics that directly respondedtotheurgentneedforformulatingcriteriathatmake comparisonoftheeffectivenessofvariousREresearchoutcomes possible.Most notably,thetopics included(1) what evaluation criteria empirical REresearchers shouldconsider for usewhen comparingREmethods,processesandtechnologies(e.g.CERE’06
http://www.di.unipi.it/CERE06/program.html),and(2)what

In particular, it is important forustounderstandwhatempiricalREevidencehasbeen accu-mulatedover time and onwhich RE sub-topics(e.g.elicitation methods, modeling techniques) or application domains. In the RE field, the first empirical study has been published in 1983
(Davis,1983),nineyearsbeforetheinitiationoftheREconference

2. TheincreasingawarenessofESEprinciplesinREresearch
IntheRE communitythere is a consensusthatcomparative evaluation of RE research efforts play a crucial role in (1) the growthofREasascientificdisciplineand(2)technologytransfer. Muchempiricalpublicationoutputwasproducedbythe commu-nityandabroadvarietyofempiricalresearchmethodsfromthe evidence-basedsoftwareengineeringparadigm(Kitchenhametal., 2004) have been used and reflected upon: systematic reviews, experiments, case studies, focus group studies, grounded the-orystudies,action research.TheREcommunity seemstowork really hard onidentifyingtheappropriate research methodolo-giestostudyREphenomenaandtheevaluationcriteriasuitable to judge RE research efforts and output (Gervasi et al., 2004;
Wieringa et al., 2005). We outline below some of the main
reasons for the growth of publications on empirical research inRE.
First,thesoftwareindustryandtheITconsultingsectorin gen-eralareincreasinglymoreawareofboththeexpensesassociated withpoorrequirementsandtheimportanceofadoptingor adapt-inggoodREpractices. Detailedmarketdataanalysesconducted over the years point to RE as the most expensivepart of any systemsdeliveryproject,regardlessofcountryororganizational settings.Similarly,researchoncriticalsuccessfactorsand produc-tivityinsoftwaredevelopmenthasbeenadvancing(e.g.Shauland
Tauber,2013;WagnerandRuhe,2008),providingclearevidence
ofthequalityofrequirementsasafactorthatcanmakeorbreak a project. Thisfuels themotivationof REresearchers to evalu-atetheextenttowhich theirproposedtechniquesaddvalueto businessesandhelpchangetheoddsforprojectoutcomes.To com-panies,thismeansgettingmoreconsciousaboutactivelysearching forpracticesthatworkedinotherorganizationsandattempting toemulatetheseorganizations’successesbasedonevaluationof existingevidence.
Second, the recent developments in large scale outsourcing worldwidehighlighttheneedofexplicitlyspecifyingrequirements veryearlyinthesystemsdeliverycycleaspartofsetting outsourc-ingcontracts(Damian,2007;DamianandMoitra, 2006;Daneva etal.,2013).Often,REbecomesa pre-projectonitsownthatis pricedseparatelyandisaimedexplicitlyat‘gettingrequirements right’.
Third,researchfundingagenciesinEuropeandNorthAmerica callincreasinglyforindustry-universitycollaborationproject pro-posalsonmulidisciplinaryresearchinwhichREplaysanimportant role,e.g.inthedevelopmentofsystemsinthedomainsofsmart cities,internetofthings,healthcareandonlinegaming.Project pro-posalsarerequired toincludeplansfor empiricalevaluation of existingREmethods,processesandtechnologiesforthepurpose ofunderstandingtheirpossiblefittotheproblemtodeterminethe requirementsforsystemsintheseapplicationdomains.
Forth,astheREfieldhasbeenmaturingforthepasttwodecades, theawarenessofexplicitandsystematicdocumentationof empiri-calresearchdesignshasbeengrowing,too.Thereisanagreementin theREcommunitytodaythatthemoreexplicitlyaresearchdesign isdescribed,theeasieritisforthereadersofempiricalREpapers toevaluatethegeneralizabilityof theresearchbeingpublished, e.g.theextenttowhichreadersmightexpecttoobservepublished resultsinothersimilarbutdifferentsettings.

For the purposeof getting indicative information on thepointsdiscussedinthiseditorialaswellastoprovide exam-ples, wechose touseScopusbecause it tracksa largenumber ofjournalsandconferencesincomputerscienceandinformation systemsresearch,whilegivingustheadvantageinfacilitatinga sin-glesearchqueryaccessitemsfromabroadvarietyofpublishers, unlikeSpringerwhenusingSpringerLink,orElsevierwhenusing ScienceDirect.

Generally, one of the goals of a map-pingstudiesandsystematicreviewsis todescribeandevaluate state-ofthe-art research byusing empirical evidence produced in primary studies (Kitchenham, 2006).

Forthisspecialissue,wecalledforcontributionsthat(1) evalu-atetechniquesfromESEforsuitabilityandinclusioninREstudies, or (2) address RE problems and solutions in new domains by deployingempiricalresearchmethods.Ourcallforpaperstothis special issue brought 17 submissions. All were subjected to a systematicmultiple-stagesreviewprocesswiththeengaged par-ticipationofatleastthreereviewers.Fivehigh-qualitypaperswere selectedforinclusioninthisissue.

4. Conclusions
Thiseditorialshowsthatempiricalapproachestothestudyof REphenomenahaveaccompaniestheREdisciplinesinceitsvery beginningandhavereceivedmuchattentionoverthepast20years, addinguptoabroadvarietyintermsofresearchmethodsdeployed, theoretical lenses and contextual settings. The RE community demonstratedremarkablecommitmenttodeployingtheoriesfrom otherdisciplinesinthedesignofempiricalREresearch. Aggregat-ingevidencefromempiricalREstudiesandgeneralizingknowledge claimshavebeenhoweverabumpyroad.Whileasteadyincrease inthenumberofempiricalstudieseachyearisapositive devel-opment,yettoabsorbthefullbenefitsoftheproducedempirical studies,empiricalresearchactivitiesneedtobecoupledwith reflec-tionsontheuseofthedeployedtheoriesandpossiblyembedthe learningandtheevidencefromtheREstudiesintotheprocessof
extendingtheexistingtheoriesfromotherdisciplinesorcreating newtheoriesspecifictotheareaofRE.
Compared to the research agendas outlined in the two RE roadmappublications(ChengandAttlee,2007;Nuseibehand East-erbrook,2000),wefoundthat:
1.TheREsub-areasforwhichempiricalREeffortswerefocused onaggregatingevidenceare:requirementselicitation, specifi-cation,prioritizationandtracingandaswellas‘user-front-end’ sub-areas as e.g. userinvolvement and stakeholder analysis. Techniquesfortheseareashave beenevaluatedbymeansof usingthesystematicliteraturereviewtechniques(Kitchenham, 2006).
2.Aggregating evidence about requirements validation tech-niques, requirements negotiation techniques (e.g. conflict resolution),requirementsscalingandREforsystemsofsystems stillremains tobedone. Effortstoconsolidateknowledge in thesesub-areascouldbealineforfutureresearch.
3.MostREempirical claim aggregation effortsfocused on pro-viding better answers to old questions (e.g. effectiveness of techniquesspecificto asub-area suchaselicitation, prioriti-zation). There is also a recent trend in evaluating evidence pertainingtousingREtechniquesinspecificnewcontextsof development(suchasdistributed).However,veryfewreviews indicatedanyfocusonnewapplicationdomainssuchasservice systems,internet-of-thingssystems,gameandhealth-care sys-tems. As theimportance of those is growing, we think that evaluatingtheevidenceprovidedbyempiricalREresearchin theseareasisaworthwhileendeavor.
4.Whiletheinterestinexplorationofusingtheoriesfromother disciplinesseemoverwhelming andleadstointenseresearch activity,verylittleseemstohavebeendoneonsharing experi-encesonhowtoborrowatheoryfromanotherdisciplineand putitinproductiveuseforthepurposeofempiricalREresearch. Neitherthereseemtobeanyefforttoaggregatethecollective learningabouttheuseoftheories.Reflectionontheoryuse there-foreisarelevantandworthwhileactivityforthefuture.
