In2011,InternationalDataCorporationreported,“Theriseinconsumer-oriented

Thetheoreticalframeworkofthisstudywasbasedontheconstructsofperceived
usefulness(PU),perceivedeaseofuse(PEOU),andbehavioralintention(BI)tousea
system.Davis(1989)describedPUandPEOUasdeterminantsimpactingBItousea
systemtowardpredictingactualsystemuse.Actualsystemusewasadirectfunctionof
perceivedBI,whereBIwasaweightedfunctionofPUandPEOU.Additionally,Davis
suggestedthatPUwasinfluencedbyPEOUandthatPUandPEOUwerejointlyinfluenced
byexternalfactors(antecedents).
FishbeinandAjzen's(1975)theoryofreasonedaction(TRA)alsosupported

Davis,&Davis,2003,p.428)althoughTAMconstructswere“bettersuitedtoInternet

ConclusionsFromFindings
Thefirstquestionaddressedthefoundationalcomponentsofthetechnology
acceptancemodel.Ashypothesized,astatisticallysignificantrelationshipwas
demonstratedbetweenITmanagers'behavioralintentiontouseenterprisesocialsoftware
technologyandvariablesofperceivedusefulnessandperceivedeaseofuse.Thedata
suggestedthatbothperceivedusefulnessandeaseofusecontributedsignificantlytoanIT
managers’intentionofadoptingandusingESStechnology.Theregressionequation
explained73.9%ofthevarianceinITmanagers’intentiontouseESStechnology,
suggestingtheimportanceofusefulnessasaleadingfactorintechnologyadoption
decisions.Both,perceivedusefulnessandeaseofusehadsignificantcorrelationstoBI,
whichwasnotsurprising;researchershavelongarguedthattechnologyacceptancefactors
(i.e.PUandPEOUrelatedtoBI),performasstrongpredictorsofactualtechnologyadoption.
ThissupportspriorresearchconductedbyDavis(1989),DavisandVenkatesh(1996),and
Venkateshetal.(2003).Thefindingsalsoassertthatthefactorsofusefulnessandeaseof
