ideal and reality in Bruce Archer`s 1968 doctoral thesis
TheStructureofDesignProcesses:idealand realityinBruceArcher’s1968doctoralthesis StephenBoydDavis,a*SimoneGristwoodb a RoyalCollegeofArt,UK MiddlesexUniversity,UK *[email protected] b Abstract: The paper centres on a single document, the 1968 doctoral thesis of LBruce Archer. It traces the author’s earlier publications and the sources that informed and inspired his thinking, as a way of understanding the trajectory of his ideas and the motivations for his work at the Royal College of Art from 1962. Analysis of the thesis suggests that Archer’s ambition for a rigorous “science of design” inspired by algorithmic approaches was increasingly threatened with disruptionbyhisexperienceoflarge,complexdesignprojects.Hisattemptstodeal with this problem are shown to involve a particular interpretation of cybernetics. The paper ends with Archer’s own retrospective view and a brief account of his dramatically changed opinions. Archer is located as both a theorist and someone intenselyinterestedinthecommercialworldofindustrialdesign. Keywords:systematicmethod;scienceofdesign;cybernetics;embodiment 1.Introduction Thispaperiscentredonasingledocument,the1968doctoralthesisofLBruceArcher, entitledTheStructureofDesignProcesses.AttheRoyalCollegeofArt(RCA)for27years, ArcherwasakeyfigureinearlyDesignResearchandadrivingforcebehindtheattemptin the1960stoberigorous,andinparticular“systematic”,aboutthenatureandpracticeof designing.Hesoughttoestablishaphilosophyofdesign(Archer1981a:33),evena“science ofdesign”(Archer1968:Foreword),aphraseoftenassociatedwithSimon’sSciencesofthe Artificial(Simon1969)(Cross2001).EssentialtothissciencewasDesignResearch, understoodnotonlyasthestudyofdesign’smethods,butalsoofitsontologyasadiscipline andanactivity.Archer’sdesignphilosophyalsoaffectededucationinschools,throughthe DesignEducationUnitlaunchedattheRCAin1977followingatwo-yearstudyfortheUK ThisworkislicensedunderaCreativeCommonsAttribution-NonCommercial4.0 InternationalLicense. 1 BOYDDAVIS&GRISTWOOD Government’sDepartmentofEducationandScience.1Archerwasavitalcontributortothe workoftheDesignCouncil,asamemberofCouncilfortenyearsandofmanyofits committees.PartlythroughhisworkwithMichaelFarr,adesignmanagemententrepreneur andeditorformanyyearsofDesignmagazine,Archerengageddeeplywiththecommercial world.2Helecturedextensivelytobusinessaudiences.Hisinfluenceextended internationallythroughhisworkinGermany,theStates,Canada,Turkey,Indiaand elsewhere.Archeracknowledgedthathelearnedmorefromsuchinteractionsthanhe mighthaverealisedatthetime(Archer1981b).

5.Themodeldisrupted Thereareanumberofdisturbancestothesystematicmodel.Theseincludecomplexity,the needtorevisitthebriefandrequirements,andtheproblemofsecuringgooddata. 5.1Complexity Archeralwaysacknowledgedthattherearemultiplesolutionstodesignproblems.Figure5 anditsassociatedthesistext(Archer1968:section2.27)makeclearthatmultiplesolutions mayoccupythespacesbetweentheboundingsurfacesoffeasibilityandacceptability.Yet onekeyreasontobepessimisticaboutanysystematicmethodistheinterdependenceof factors.Fixingoneproblemopensanother,andtypicallyunforeseenconsequencesoccur, problemsofcomplexitycharacteristicofsocio-technicalsystems(Johnson2010:120)–such ashospitalbeds.Evenexhaustivecomputationmaynotdothetrick:“toderiveatrend whichwouldpointtoanidealsolution,isonlyjustbecomingfeasibleandyetmightneverbe attainablebecauseofthelargenumberofvariablefactorswhicharenotalways interdependent”(Archer1956a:14).11Archer’scolleagueatUlm,HorstRittel,memorably characterisedtheseas“wickedproblems”indialoguewithCWestChurchmanatjustthe timeArcherwasfinalisinghisthesis.Bothauthorsfeatureinthethesis(Churchman1961; Rittel1965),andheexplicitlynotesthesignificanceofdependence(Archer1968:endnote 60).AcharacteristicpassageintheRittelchaptercitedbyArchercouldbeadescriptionof problemslikethehospitalbed:“...itcanbeexpectedthattheexchangeofassociations betweenseveralpersonsislikelytoraisethisthresholdsinceeachassociationactsasanew stimulusontheotherpersons.InthismannernotonlyCisincreasedbutalsothediversity oftheassociationsproduced.Thisdiversityisgreatestwhentheindividualreservoirsof associationsoverlapleast(i.e.theyarespecialistsfromwidelydifferentfields)”(Rittel1965: 209-210). 5.2Requirementsincontention DespitediagramslikeFigure6thatappeartoshowthebrieflyingoutsideandpriortothe designprocess,Archeractuallyacknowledgesatseveralpointsthattherequirementswhich thedesignersthoughttheywereworkingtomaybesubjecttorevisionatalmostanypoint. 10 ThisleadsArchertotheoddcontentionthatacouturierisdesigningevenwhenmakingagarmentonthestand–butonlyprovidedthis isnotthefinisheditembutaprototypeforagarmentthatisgoingtobemadesubsequently(Archer1963PartTwo:70). 11 Giventhecontextandflowofargumentatthispoint,itseemspossiblethatArchermeanttoendthissentence“arenotalways independent”.Inanycaseitisclearthathebelievesthereissignificantinterdependencebetweenfactors. 10 TheStructureofDesignProcesses:idealandrealityinBruceArcher’s1968doctoralthesis AsRittelputitlater:“...theirritatingthingisthat,dependingonthestateofsolution,the nextquestionforadditionalinformationisuniqueanddependentonthestateofsolution youhavealreadyreached”(Rittel1972:392).InArcher’swords,“Duringthecourseofthe problemsolvingactivitynewobjectivesmaytendtoformandreform”(Archer1968:2.29); “Thecompletesetofobjectivesisonlyrarelydefinableatthebeginningoftheproject.Most ofthememergebymutualconsentastheprojectprogresses”(Archer1968:6:15).He seemscomfortablewiththis,eventhoughwemightconsiderthatitunderminessomekey aspectsofhissystem:“Itisopentothearbiterorarbitersinaproblemtomanipulatethe importanceratingsinanywaytheywish,andtorevisetheirratingsatanystagetheywish, soastorepresenttheirtrueaimsandinterestsastheconsequencesoftheirdecisions emerge,orfreshinformationbecomesavailable.”(Archer1968:3.30).Andthesearenot justminorrefinements:“anyeffectivedesignproceduremustthereforepermitradical reappraisaloftheproblematanystage.”(Archer1968:6:17emphasisadded).Againthe real-worldcomplexitiesofdesignprojectsseemtohavehadaprogressiveinfluenceon Archer’sthinking,butwithoutyetundermininghisfaithinthesystem. 5.3Lackofgooddata ForArcher,thedesignerorengineermustworkwiththebestpossibleinformationrather thanrelyingonintuitionorcustomandpractice.ORandO&Mhadbothpromotedthe provisionofadequatedatainordertobeeffective.Inergonomics,Joneshadbeen advocatingtheuseofstrongdataformorethanadecade(Jones1954).Dreyfuss’influential anthropometricfileshadbeenpublishedrepeatedlyintheprecedingtenyears(Dreyfuss 1959).YetinkeyareasthatArcherconsideredessentialtodesign,includingaesthetics,he acknowledgesthelackofgooddata.Aworkcitedfrequentlyinthethesisconfrontsthetwin problemsofinterdependenceanduncertainty(TavistockInstitute1966).Archerbemoans thelackof“acorpusofknowledgeorasetoftechniquescapableofprovidingrational aestheticdecisions”(Archer1968:8:17).Thisforhimisalackofgoodinformation,nota fundamentaldifficultyinprocessingandusingqualitativedata:“itshouldbepossibleto collectdataandtocarryoutanalysesoftrendsandprobabilities,usingtechniqueswell developedinthenaturalandsocialsciences”(Archer1968:8:16);“Theprincipaldistinction betweenphenomenafromtheoperationalpointofviewisthereforenotintheir‘qualitative v.quantitative’characterbutintheir‘knownv.notknown’character(Archer1968:9.4).

AbouttheAuthors: Stephen Boyd Davis is Professor of Design Research at the RCA, London, where he leads staff research in the School of Design. His research focuses on the representation of knowledge through computation, depiction and diagramming, with an emphasis on chronographics. Dr Simone Gristwood is Lansdown Research Curator at Middlesex University. Her research focuses on uncovering the histories of the use of computing in the arts and design from the 1960s onwards, primarilythroughinvestigatingthearchivesofpioneers. 19
