INTRODUCTION

McKinseyGlobalInstitutebroughtnationalspotlighttotheterm“bigdata”andtheexponentialgrowthofdatainmajorindustries(Manyika,et.al.,2011).Autonomousvehicles,advancedhealthcareresearchandpervasivevirtualassistants,socialmediaanalytics,andInternetofThings(IoT)areafewusecaseswheredatascienceandmachinelearningarebeingrapidlyadopted.Theadoptionofartificialintelligencemachinelearning/deeplearning(AIML/DL)applicationsincorporationsisforcinginformationtechnology/informationsystems(IT/IS)practitionerstoreassessthepillarsnecessarytosuccessfullyimplementbusinesssolutions(BanavarandCooper,2016)(Samuel,et.al.,2017).TheITindustryhasexperiencedcomputingerashiftsbeginningwiththefirsteraoftabulatingmachinestotheseconderaofprogrammablecomputerstotoday’seraofAIML/DL.Tabulatingmachineswereheavilyfocusedontheapplicationofmathematics.Programmablecomputerswerecodedwith“if,then,else”instructionstoproduceadeterministicoutput.Today’sAIML/DLapplicationsareabouttheprobabilisticoutcomesbasedoncontext(BanavarandCooper,2016).

ThisresearchusedtheSkansibroadfieldsofAIasabasisfordiscussionandinterviews.ThesefieldsprovidethebackgroundtoassesstheIT/ISpillarsforAIML/DLbusinessapplicationdevelopment.TheidentifiedIT/ISpillarsare:

DataScience–theprimaryroleistofollow“asetoffundamentalprinciplesthatsupportandguidetheprincipledextractionofinformationandknowledgefromdata”(ProvostandFawcett,2013,p.52).

ThepotentialofAIML/DLdependsontheavailabilityoftalentandtechnologytoharnessitsvalue(Boisvert,et.al.,2017).AsbusinessAIapplicationsareincreasinginfrequencyandcomplexity,IT/ISskillsareevolving.ForresterResearch(Goetz,2017)discoveredthatenterpriseswanttogetvalueoutoftheirdatafasterandatscale,howevertechnologyalonecan’tsolvethischallengeandaddingroleswiththesoleresponsibilityofactivatingdataisnecessary.DavenportandPatil’sHarvardBusinessReviewarticle(2012)identifieddatascientistsasanimportantandemergingrolethathaslittleconsensusonwheretherolefitsinanorganization,thevaluetotheorganization,ortheprocessofdiscovery.Asaresult,itwasnecessaryfordatascientisttocrafttheirowntoolsandresearchapproaches.WilliamChen(2017),aDataScientistatQuora,summarizesthefiveskillsandcompetenciesthatheseesisimportantforadatascientistrole.Thisincludes1)programming(augments,largedatasets,createtools);2)quantitativeanalysis(experimentaldesignandanalysis,modelingofcomplexeconomicorgrowthsystems,machinelearning);3)productintuition(generatinghypothesis,definingmetrics,debugginganalysis);4)communication(communicatinginsights,

datavisualizationandpresentation,generalcommunication);and5)teamwork(beingselfless,constantiteration,sharingknowledge).Theauthorsnoticethatthreeofthefivecompetenciesarenottechnicalskills.

Inrecentyears,theemphasishasbeenonestablishingandcultivatingthedatascientistrolewithincorporations.ThefocusonthedatascientistrolehasresultedinabottleneckwhenthereareinadequateresourcestoefficientlybuildtheAIapplications.Forrester(2017)discoveredtheneedtogrowtheroleofdataengineerequallytothedatascientistroletosuccessfullydeployAIML/DLapplicationsbystating:

Theycontinuebystatingthatdatadevelopmentrolesarehighlyoutsourcedandtransient.Thistransientnatureoftheseengineerandscientistrolesmeansthatknowledgefromdevelopmentprojectsarelostwhenresourcesarereassigned.Dataarchitectsareoftennecessaryfordesignworkforplatformsandtoprovidedataaccesstoadhocrequests.Therefore,asdataengineeringevolves,dataarchitectureisbecomingapeerandguidestheinvestmentsrequiredfordatasourcesandserviceswhileprovidingtheplatform,frameworks,andreferencearchitectures.

DataEngineering–Thisroleisbecomingmoreimportantandmoreinclusiveofskillspreviouslyheldbythedatascientist.Thedataengineerhastheprimaryroleofdatapreparationandmanipulation,fromingestiontoformatting/transformationtostoragefortheconsumptionbythedatascientist.OfthefourIT/ISpillars,thedataengineerhashadthemostimpactonamountoftechnicalskillsrequiredtobesuccessful.
