Althoughcompaniesmanageprojectportfoliosconcordantlywithprojectportfoliotheory,theymayexperienceproblemsintheformofdelayedprojects,resourcestruggles,stress,andalackofoverview.Basedonaresearchprojectcompromisedof128in-depthinterviewsin30companies,weproposethatakeyreasonwhycompaniesdonotdowellinrelationtoprojectportfoliomanagement(PPM)isthatPPMoftenonlycoversasubsetofon-goingprojects,whileprojectsthatarenotsubjecttoPPMtieupresourcesthatinitiallywerededicatedtoPPMprojects.WeaddressanddiscussthedilemmaofwantingtoincludeallprojectsinPPM,andaimingatkeepingtheresourceandcognitiveburdenofdoingPPMatareasonablelevel.

1.Introduction

Atanygivenpointintime,mostcompaniesengageinmanyprojects.Someoftheseprojectsmayrelatetoproductdevelopmentandmarketing,othersrelatetochangesinworkprocessesandproductionflows,whileyetothersrelatetocompetencydevelopment,strategicturns,theimplementationofnewITsystems,environmentalissuesetc.

Akeymanagerialtaskistodedicateresourcesacrossalloftheseprojects(aswellasdodailywork)andconsequently,managementacrossprojects(projectportfoliomanagement(PPM))iscriticaltocompanyperformance.Thispaperisbasedonalarge-scalequalitativestudy,whichshowsthatmanyproject-orientedcompaniesdonotperformwellwhenitcomestoPPM.Thisrelatestotheinabilitytoaccomplishprojectsthatareinitiated.Inparticular,weidentifythefollowingproblems:

(1)Projectsarenotcompletedaccordingtoplan(ortheyevenpeteroutduringtheirprojectlifecycle);

(2)Managementandemployeesfeeltheylackabroadoverviewofon-goingprojects(especiallywhenthenumberofon-goingprojectsincreasesasmoreandmoreprojectsarenotcompletedaccordingtoplan);

(3)Peopleexperiencestressasresourcesarecontinuouslyreallocatedacrossprojectsinordertomakeendsmeet.

Theseobservationsareespeciallyinterestingbecausethecompanieswereincludedintheresearchprojectbecausetheyweresupposedtobeespecially,experiencedinPPM,andbecausetheyactuallyengageinPPMaccordingtotheextantbodyofliteratureonPPM.Forexample,partofthecompanies’PPMincludedanefforttopickthebestprojectsonthebasisofexplicitorimplicitcriteria,andanefforttoallocatesufficientresourcestotheseprojects.

However,despiteefforts,topractice‘good’PPM,thesecompaniesexperiencesevereproblemsinrelationtoPPM–especiallyinlettingenoughresourcesgointothe‘right’projects.ThepurposeofthispaperistoconfrontPPMasadvocatedbynormativetheorieswithactualPPMpractices.Hence,thepurposeistoconfrontPPMtheorieswithPPMasperceivedbymanagersandotheremployeesforwhomPPMispartof,oraffects,theirworkconditions.

However,inthispaper,wearemoreinterestedinPPMasenactedbycompaniesthaninuniversallytrueperceptions.Hence,weadheretoWeick’s[1–3]notionofenactmentasthepreconceptionsthatareusedtosetasideaportionofthefieldofexperienceforfurtherattention.InregardtoPPM,enactedprojectsarethustheonesmanagementsetsasideforfurtherattention(i.e.PPM).Assuch,wefocusespeciallyonwaysactorsdefineorenactprojects[4]andmakesenseofhowtomanagethesumoftheprojects.Drawingonthisperspective,weaccountforfindingsthatsuggestwhycompaniesthatdoengageinPPMstillexperienceproblems.

2.Projectportfoliotheory

ThispaperdrawsonArcherandGhasemzadeh’s[5,p.208]definitionofprojectportfoliosas‘‘agroupofprojectsthatarecarriedoutunderthesponsorshipand/ormanagementofaparticularorganization’’.Henceforth,wedefinePPMasthemanagerialactivitiesthatrelateto

(1)theinitialscreening,selectionandprioritisationofprojectproposals,

(2)theconcurrentreprioritisationofprojectsintheportfolio,

(3)theallocationandreallocationofresourcestoprojectsaccordingtopriority.

Forquitesometimeresearchershavesuggestedthatlowcompletionratesfornewproductdevelopment(NPD)projectsandnewproductfailurerelatetoresourcedeficienciesinkeyareas[6,7].Furthermore,whileahostofresearchers[8–10]havefocusedonthedimensionofPPMthatconcernsprocessesrelatingtoselectionofprojectstobeincludedintheportfolio,researche.g.[11]alsoincreasinglyfocusesontheday-todaymanagementoftheprojectportfolio.

3.Methodology

Overaperiodoftwoyears,wedidempiricalresearchonhowcompaniesmanagetheirentirerangeofprojects,e.g.renewalprojects,strategicprojects,ITprojects,departmentallyspecificprojects,andproductionbasedprojects.Inrelationtotheselectionofcompaniestobeincludedintheempiricalstudy,akeycriterionwasthatthestudyshouldcoverawidevarietyofindustries.Asaresult,theempiricalstudycovers30companiesfromindustriesasdiverseas,e.g.mobiletelephonecommunications,finances,energy,pharmaceuticals,toys,software,andfoods.

However,duetothefactthatwewerelookingforcompanies,wheretheamountofon-goingprojectssuggestedtheywereengagedinPPM,thestudyisbiasedtowardslargercompaniesaswellascompaniesthatdefineatleastasubstantialpartoftheiractivitiesasprojects.Thedegreetowhichthecompaniesparticipatedinthestudyvaries.Hence,halfofthecompaniesarelabelled‘innercircle’companiesduetothefactthatwedrewextensivelyonthese15companies.Forexample,inthesecompaniesmoreinterviewswereconductedatvariouspointsintimeandatvariousorganizationallevels.Hence,alongitudinalperspectivecharacterizestheinvolvementofthesecompanies.

4.Managerialimplications

Akeyfindingisthatthegapbetweenrequiredandavailableresourcesisverymuchattributabletotheexistenceofahostofsmallerprojectsthatneverbecomepartofenactedprojectportfolios.Thus,atanaggregatedlevel,theempiricalstudysuggestssmaller,un-enactedprojectsqualifyasresourcescrunchersinsofartheyarenotconsideredtobeapartofenactedprojectportfolios.Inordertoovercomethiscrunchinresources,twosolutionsseemobvious:

(1)Enactingmore,i.e.havingPPMembraceallprojects.

(2)Allocatingmoreresourcestoapoolofloosely-controlledresourcesfortheun-enactedprojectstodrawon.

5.Researchimplications

Theempiricalstudyelaboratesonthe‘‘significantshortageofresourcesdevotedtoNPD’’thatCooperandEdgettargueisthefundamentalproblem‘‘thatplaguesmostfirms’productdevelopmentefforts’’.

Ourworkespeciallysuggeststhattheshortageofresourcesdevotedtoenactedprojectsisnotaproblemthatprimarilyarisesinrelationtotopmanagement’sPPM.Onthecontrary,in-good-faithtopmanagementdedicatesresourcestoenactedprojectsonthebasisofsoundPPM.However,whattopmanagersdonotdoistakeintoaccountthehostofsmallerprojectsthatindividualsinitiateand–moreimportantly–topmanagersignore(oratleastheavilyunder-estimate)theamountofresourcesthatthesesmallerprojectstieup.Hence,wearguethatespeciallythecrunchinresourcesmaybeattributabletotheun-enactedcompetitionforresourcesthatsmallerprojectssubjectenactedprojectsto.

Consequently,thekeycontributionofourempiricalworktoresearchisthatitemphasisesthatifwewishtostudyPPM(andespeciallyifwewishtorelatePPMtoprojectperformance),wemightbebetterofftakingintoaccounttheentirerangeofprojectsthatactual(notenacted)portfoliosarecomprisedof.Thus,ifweasresearchersonlyenacttheprojectsthatareneatlylistedbytopmanagement,thenourresearchwillneglectthehostofprojectsthatarenotsubjecttoPPM,projectsthatnonethelesstakeupvaluable,andscarce,resources.

Thefactthattheempiricalstudyincludesinterviewswithmanagers,i.e.thosewhodoPPM,andinterviewswithpersonnelatlowerorganisationallevels,i.e.thosewhoseworkissubjecttoPPM,isthereasonwhywewereabletoidentifyun-enactedprojects.Thus,researchersinterestedinPPMshouldbecarefulnottorelytooheavilyonamanagementperspective.

6.Conclusionandlimitations

Themainconclusionisthataslongassomeprojectsareun-enacted,companiesmayexperienceadrainonresourcesthatreducesthetimeandresourcesactuallydevotedtoprojectssubjecttoPPM.Hence,eachindividualcompanyshoulddecidewhetherornotallprojectsshouldbepartofPPMandiftheendresultofsuchadecisionisnottomakecomprehensiveprojectlists(i.e.liststhatincludeallminorprojects),thenmanagementshoulddecidehowmanyresourcesshouldbesetasidefortheplethoraofsmallprojectsthatdonotappearontheprojectlist.

Onewayinwhichthecrunchinresourcescanbereducedisbyensuringthatsmallerprojectsdonottakeupacriticalportionoftheresourcesthatare–officially–setasideforthecompletionofprojectssubjecttoPPM.However,duetotheexploratorynatureofthestudyaccountedforinthispaper,ourfindingsrelatefarmoretowhatcompaniesactuallydo(positivetheoryinHunt’sterms),ratherthantowhattheyoughttodo(normativetheoryinHunt’sterms).Althoughgeneratingpositivetheoryisindeedacrucialfirststep–especiallyinrelationtothefutureofPPMtheory
