Information systems (IS) success in non-organizational contexts: Examining the DeLone and McLean IS Success Model in the context of an online stock trading environment (William D. DeLone, Ephraim R. McLean)

This dissertation examined the IS success model of DeLone and McLean to determine if it applies to users who are not directly part of an organization in the same way that it applies to employees in an organizational context. Specifically, it was concerned with examining individuals who are customers of stock trading companies and who use a Web-based online stock trading information system provided by the companies.; The dissertation used a qualitative positivist case study approach. To increase the external validity in the study, a theoretical framework was used in the research design phase. The use of this theoretical framework helped in interpreting the results in the analysis phase. The updated DeLone and McLean Information Systems (IS) success model (2002) was the theoretical framework used in the study. Based on the updated model, three propositions were introduced in the study to examine the effect of IS system quality, information quality, and service quality on online stock traders' use (and intention to use) and user satisfaction with the system, as well as the net benefits introduced to them as a result of using this system.; The targeted population for this study consisted of online stock traders in the U.S. stock market. The study focused on active individual traders defined as those who place at least 30 trades per quarter. To be included in the study, private online stock traders must also have traded stock via traditional brokers or telephone systems to compare their performance before and after online trading. Forty investors (subjects) completed a detailed questionnaire (there were 50 questions) online. Each question response was coded and pattern matching was used for analysis to compare the data to theoretical propositions.; The findings and results of this study demonstrate that system quality, information quality and service quality of the online stock trading system have a positive effect on information system use and satisfaction of the online traders. It was also shown that the use of the online trading system and traders' satisfaction have a positive effect on introducing net benefits to online stock traders. These results are consistent with the study's propositions and the updated DeLone and McLean IS Success Model.
